No, at low temperatures PVC becomes increasingly brittle and the tendency to crack (stress-cracking) under the influence of adhesive residues increases.
If it is absolutely necessary to bond at low temperatures then we advise you to warm the elements to be joint and the cement to a temperature above +5° C, preferably to a temperature between 20 and 25°C, before performing the bonding. This can be achieved, for example, by using warm air. Use suitable equipment for this (explosion proof).
With correct joining, the joint can withstand near enough the same temperatures as the PVC pipes and fittings.
For pressure systems, the temperature resistance is +60°C, depending on the pressure.
For drain systems, it is temporarily up to +95°C.
No, PP cannot be glued. PP connections need to be made with the help of sleeves or rubber ring seals.
The best thing to do is fit a new piece to the damaged pipe. If this is not immediately possible then Griffon UNI-100® can be used as a repair cement.
The rule in principal is: If the pipe is resistant then the joint is also resistant.
An exception to this is the chemical resistance of joints to a limited number of extremely aggressive chemicals such as concentrated inorganic acids, strong lye and very strong oxidising agents. In these cases, use Griffon HCR-36 PVC cement.
Not all PVC cements are suitable for applications containing flexible PVC hoses. For these, Griffon has a special cement in its assortment, Griffon WDF-05.
Use PVC cleaner. This contains solvents that dissolve PVC cements residues provided they have not yet fully cured.
For a slow drying PVC cement, UNI-100 GT is the most suitable. This has a longer assembly time and is therefore suitable for pipes with a diameter of up to 800 mm.
For connections that are 100% waterproof and tensile resistant, it is important that they are made in accordance with the instructions for use. Cleaning, chamfering the pipe ends, cleaning gluing surfaces, applying sufficient cement evenly to both surfaces are all essential aspects in this.
To be certain that each connection is perfect, Griffon Cleaner must be used. This not only degreases the glue surfaces but the solvents in the Cleaner penetrate the material as a result of which the adhesive adheres better.
No, the combination of Griffon PVC Rigid PVC Solvent cements and Cleaner guarantees the perfect connection, provided that the bonding instructions are followed. It is only useful to scour the bond surfaces if the PVC pieces are discoloured, perhaps because they have been kept outdoors.
When the pipe and fitting are slid into each other, the still wet cement layers must flow into each other. If you do not chamfer, the cement will be (partially) pushed inside, instead of into the connection. Result: a risk of leakages and less strong connections.
After forming the connection, you can still twist the pipe or fitting somewhat in order to finish it in the correct position. After this, you must not burden or twist the connection. This can damage the joint.
Consult the tables on labels and documentation sheets that indicade the drying times depending on the temperature, pipe diameter and pressure load.
For drain systems, a drying time of 1 hour (at temperatures above 10°C) is sufficient.
With connections made with WDF-05, pressure can be set on the PVC pipe system very quickly. For example, 10 bar after 30 minutes up to a diameter of 50 mm. Consult the label for the drying times depending on the temperature, pipe diameter and pressure.
We always cement to join on a clean and dry surfaces in accordance with the bonding instructions. If circumstances make this impossible then WDF-05 is the best choice. Generally, this will provide good connections in less than ideal damp conditions.
No, you can only use fluxes with the KIWA seal of approval for drinking water pipes. The non-approved fluxes can damage copper piping.
Flon-100 is adjustable because of the combination of PTFE sealant cord and lubricant. The lubricant can be found in the lubricant dispenser located at the bottom of the packaging. This can be seperated from the top part. This dispenser contains a lubricant that makes it possible to adjust the connection by 45° (1/8 turn).
There are no approval requirements for PTFE sealant tape with regard to drinking water applications. PTFE is inert and react near enough to nothing.
No, S-39 is not poisonous but the residues are too corrosive to be applied to copper pipes. If the pipe is not flushed out after soldering then the flux residues will corrode the copper. This can cause pitting corrosion.
Thus use a KIWA approved flux. If the residues remain in the system, they will not corrode the copper. These residues are 100% soluble in water and are flushed out during the filling and use of the installation.
The ingredients used are correct. It is however important that the connection is not heated too much. The lead-free solder has a melting point of 220°C. The flux loses its properties about 300°C. It is therefore best to remain under 300°C. You can check this by occasionally holding the solder against the warm pipe/fitting. As soon as it begins to melt and flow into the capillary, do not warm the pipe (too much) any more.
European Construction Products Regulation
This regulation (CPR) took effect on 1 July 2013 and lays down the minimum requirements for construction products in the areas of safety, fire resistance and mechanical strength, among others. If a harmonised European standard has been established for a specific product group, the manufacturer has an obligation to demonstrate compliance with the relevant CE requirements and to label the product with the CE logo. In addition, a Declaration of Performance (DoP) must be available, describing the way in which the products have been tested and indicating the level of performance achieved by the product. PVC Adhesives and Chemical Anchors are subject to this European Construction Products Regulation. Sealant are covered by the regulation as of 2014. The corresponding Declarations of Performance (DoPs) are available on the product information page of each product to which it applies.
