In principle, the rule applies: If the pipe can withstand it, then the adhesive joint can also withstand it.
An exception to this is the chemical resistance of adhesive compounds to a limited number of highly aggressive chemicals, such as concentrated inorganic acids, strong alkalis and very strong oxidizing agents. In these cases, use the Griffon HCR-36 PVC glue.
Yes! Due to the high research costs and/or the high risks, there is a chance that substances will be withdrawn from the market. This could have an impact on the availability of our products.
When the connection is made, the pipe or fitting can be twisted slightly to bring it into the correct position. After that, you don't have to strain or twist the connection anymore. This may damage the adhesive joint.
Only with the relatively slow-drying adhesive GR-95 for drainage systems you have more time to adjust the connection.
No, unfortunately this is not possible. The Griffon PU Foam is a moisture-curing product and will only harden on the outside of the foam when applied in an enclosed space. This cured exterior prevents the foam from hardening on the inside.
As a result, proper foaming of the foam is not obtained.
No, only the fluxes with the KIWA quality mark may be used for drinking water pipes. The non-approved fluxes can cause damage to the copper pipe.
No, at low temperatures, PVC becomes more and more brittle and the tendency to form cracks (stress-cracking) under the influence of adhesive residues will increase.
If it is necessary to glue at low temperatures, we recommend that the parts to be glued and the glue are heated to above +5°C, preferably to approx. 20 to 25 °C, before carrying out the bonding. This can be done, for example, by means of warm air. Use suitable equipment (explosion-proof) for this purpose.
No, you can't use the Hydra for this. After curing, the hydra "stone" is hard and will tear loose due to the action of the materials.
The central heating water treatment products are harmless to all components (copper, aluminum exchangers, radiators, pipes, various components, 3-way valve, O rings) of the system. The products are acid-free and pH neutral.
When the pipe and fitting are pushed together, the adhesive layers that are still wet must flow into each other. If you don't chamfer, you slide the glue (partially) inwards instead of into the joint. As a result, there is a risk of leaks and weaker connections.
No, the products work at both low and high temperatures. It is important that the products can circulate throughout the system.
The central heating water treatment products are super concentrates. 1 cartridge per 100 litres of system capacity gives an ideal concentration and effect of the product. Underdosing can lead to inadequate efficacy. Overdosing does not affect improved operation or adversely affect the installation components.
No, CV-Leaksealer will only seal holes with a maximum diameter of 1 millimetre. Furthermore, it does not affect the content of the installation.
Pick up the tables on labels and documentation sheets, where drying times are indicated depending on temperature, pipe diameter and pressure load.
For drainage systems, a drying time of 1 hour (at temperatures higher than 10 °C) is sufficient.
For 100% watertight and tensile connections, it is important that connections are made according to the instructions for use. Cleaning, chamfering the end of the pipe, cleaning the adhesive surfaces, applying sufficient glue evenly on both surfaces are essential.
The means used are correct. However, it is important not to overheat the connection. The lead-free solder has a melting point of 220°C. The flux will lose its effect above 300°C. It is therefore important to stay below 300°C. This can be checked by holding the solder against the hot tube/fitting from time to time. As soon as it melts and flows into the capillary, the tube no longer heats (too much).
As a handy tool, the S-39 copper (Cu) KIWA can be used as a flux. This one has a handy color indicator. If the red color disappears, the solder can be added.
It is best to remove wet polyurethane foam that has not yet hardened with Griffon Cleaner or PU Foam Cleaner . Cured polyurethane foam residues on the skin can be removed with Griffon hand cleaner scrub. Cured polyurethane foam on other surfaces can only be removed mechanically.
To do this, use PVC cleaner. It contains solvents in which PVC adhesive residues dissolve, provided that they have not yet fully hardened.
With WDF-05 made connections, pressure can be put on the PVC piping system very quickly. e.g. 10 bar after 30 minutes up to diameter 50 mm. Pick up the label for drying times depending on temperature, tube diameter and pressure.
There is no guarantee that the quality will never change. Changes can be made if the regulations (KIWA-ATA) change. If there is actually a change in quality, this will in any case be announced in advance.
No, these types of plastic cannot be glued. They are usually fused together industrially by high heating.
PP = Polypropylene
PE = Polyethylene
PA = Polyamide=Nylon
PTFE= Polytetrafluoroethylene
Follow the text on the packaging and absolutely do not process below 5 degrees.
Poly Max® hardens under the influence of moisture. This is a chemical reaction. At low temperatures, absolute humidity is low and reactions are very slow.
It is possible that the bus has been moored. By lying down, the valve can stick to the outflow opening and nothing will come out of the canister.
To ensure that every connection is perfect, one should use Griffon Cleaner. Not only does it degrease the adhesive surfaces, but the solvents of the Cleaner penetrate the material, so that the glue will adhere better.
No adverse effects are known and to be expected.
The products are buffered and pH neutral. The water will be brought to the ideal pH of 7.2 – 7.6, and kept there.
No, S-39 is not toxic, but its residues are too corrosive to be used in copper pipes. If the pipe is not flushed after soldering, the flux residue will act on the copper. This can cause pitting corrosion.
Therefore, use a KIWA-approved flux. If these residues remain in the system, they will not affect the copper. These residues are 100% water-soluble and are rinsed out during filling and use of the system.
On Pur foam canisters there is a notation about the fire class that the foam meets. This runs from B1 to B3. B1 foam is fire resistant. B2 foam is fire retardant and B3 foam is flammable.
This B2 standard includes the following:
According to the DIN 4102-1 standard, standard test pieces of polyurethane foam are prepared with a width of 90 mm, a length of 190 mm and a height of approx. 60 mm.
The test pieces are flamed for 15 seconds, after which they start to burn themselves. These flames must be extinguished within 20 seconds and the flames must not exceed 150 mm in height.
PUR foams with a B1 standard must also meet these requirements and also an additional requirement whereby the PUR foam is exposed to hot air of up to 200°C in a special construction. The PUR foam must not burn, smoulder or melt.
When using B1 foams, the foam should always be covered with a mineral material during use. B3 foams do not comply with both B1 and B2.
For a slower drying PVC adhesive, the UNI-100 GT is the most suitable. It is equipped with a large open time and is therefore even suitable for pipes up to 800 mm in diameter.
With correct bonding, the adhesive connection can withstand almost the same temperatures as the PVC pipes and fittings.
For pressure systems, the temperature resistance, depending on the pressure, is up to +60 0C.
For drainage systems, this is temporary up to +95 0C.
Manufacturers, distributors and importers have the obligation to register substances with a comprehensive set of data on safety for humans and the environment. There are different deadlines and different requirements for the depth of the data. This depends, among other things, on the volume and harmful properties of the substance. Information about and the manageability of risks must be passed on between companies in the chain. In preparation for the Registration, users of substances (including those contained in adhesives, sealants, coatings, soldering fluids, lubricants, etc.) must pass on information about the use to their suppliers. A ban is introduced for the chemicals of the highest concern, with the EU being able to grant Authorisation for production and use under strict conditions.
The system will function optimally when all sludge and corrosion products have been removed, and then protected with Protector. Possibly. Leftover residues can still cause problems (thermostatic valves, etc.).
Not all PVC adhesives are suitable for plasticizer-containing flexible PVC hoses. Griffon has a special adhesive for this in its range, the Griffon WDF-05.
In the future, you will get products of which all health and environmental risks are more clearly documented for your application. Because many applications are the same, our industry will draw up a number of so-called "generic exposure scenarios" and pass them on to the raw material suppliers. As soon as these have been drawn up, we will ask whether such a scenario also applies to you. Griffon will ask its raw material suppliers to register the substances used and, if necessary, to test them for the way in which our products are used in your premises. The end result of the overall process will be better protection of the environment and a healthier working and living environment.
This Regulation (CPR) is in force from 1 July 2013 and lays down the minimum requirements for construction products in terms of safety, fire resistance and mechanical strength, among other things. If a harmonized European standard is available for a product group, it is mandatory to demonstrate that the specific CE requirements are met and to provide the product with the CE logo. In addition, a Declaration of Performance (DoP) must be available, which describes how products have been tested and what performance is achieved with the product. PVC adhesives, chemical anchor and sealants from 2014 onwards are covered by this European Construction Products Directive. The corresponding Declarations of Performance (DoPs) are available with the relevant product.
A DoP is a Declaration of Performance. This describes how a product has been tested and what performance is achieved with the product.
Griffon has started making a risk analysis. Based on the science we have now, we look at:
- The hazard class of the substance.
- The uniqueness of the fabric for our products.
- The chance that it may not be registered or will be withdrawn from the market.
We will use this analysis to be able to offer you an alternative in time.
REACH is a new European regulation that covers the production, import and use of chemical substances on their own or present in preparations. The abbreviation stands for Registration, Evaluation, Authorisation and Restriction of Chemicals. The essence of REACH is that, in principle, a company must know the risks of all the substances it supplies and must identify measures to control those risks. With the introduction of REACH, the responsibility for adequate risk management of chemicals shifts from the government to the private sector.
The products are all acid-free and pH neutral. Limescale will therefore not be dissolved by the products. Limescale deposits can be prevented by using the CV-Protector.
The aim of REACH is to ensure a high level of safety for humans and the environment in the production and use of chemicals. REACH will make more information available on substances used. As a result, communication about these substances will be improved in the chain from producer to end user and vice versa.
The Flon-100 is adjustable by a combination of PTFE sealing cord and lubricant. The lubricant is in the lubricant dispenser attached to the bottom of the package. This can be removed from the top. This dispenser contains a lubricant that makes it possible to adjust the connection by 45° (1/8 turn).
The REACH legislation came into force on 1 July 2007. Before 1 December 2008, all substances had to be notified to the REACH registration office in Finland. As of 1 December 2010, the risks of the most dangerous substances are known. By 1 June 2018, REACH must be implemented for all substances.
The Hydra must be dried before use. After drying, at least 24 hours, the sealant should be fired slowly. The heat will cause the sealant to harden and reach its final heat resistance.
The CPR on PVC adhesives and chemical anchors has been in force since 1 July 2013. As of 1 July 2014, sealants are covered by this CPR.
A DoP can be found in the product information on the products on which CRP is in effect. If you have any questions, you can ask them via the contact form.

We hope to have informed you sufficiently for this moment.
In order to be able to answer all your questions adequately and to be able to advise you properly, Griffon has set up a REACH project group. If you have any questions, don't hesitate to contact Griffon! We will do our utmost to provide you with the correct information.
We always recommend bonding on clean and dry surfaces according to the adhesive instructions. If this is not possible due to circumstances, the WDF-05 is the best choice. This will generally give good connections even under less than ideal, humid conditions.
A neutral, acid-free silicone sealant should be applied to plastic surfaces such as acrylic baths and acrylic shower trays. This is the Griffon S-200.
For this application, you can use Poly Max® High Tack Express. This adhesive does not affect any surface and is water resistant.
Make sure that the glue is applied in vertical stripes. Poly Max® needs moisture to harden. This moisture must come from the ambient air. By applying vertical stripes, ventilation is always obtained.
PVC adhesives and chemical anchors fall under this European Construction Products Directive. As of 1 July 2014, sealants are also covered by this CPR.
It is important that an acid-free sealant is used with these materials.
S-200 is an acid-free silicone sealant, which does not affect fragile materials.
