Soudal | Silicone Sealant
Soudal Silirub ® Pro N is an Airtight, Low Modulus Premium Grade Neutral Cure Silicone Sealant. It is virtually odourless with fast skinning time and final cure.
Soudal Silirub ® Pro N is a 100% Pure Silicone Sealant with no shrinkage. Extra thick-bodied. Excellent toolability and Primerless Adhesion on common construction materials (i.e Glass, Plastics, Masonry Substrates, Metals and Wood).
Soudal Silirub ® Pro N has high movement capability with resistance to weathering and many chemicals. High and low temperature resistance. It contains a strong Fungicide (XS1 Fungicide) to prevent unsightly Black Mould growth.
Soudal Silirub ® Pro N Can be used with all types of Glass (Except Self-Cleaning types).
This product should not be confused with 'Silirub® N' which is a much lower grade of Neutral Cure Silicone Sealant.

Tests carried out in Soudal Laboratories show that Silirub® Pro N is compatible with most edge seals of insulating double glazing and conventional PVB films.
External testing at TÜV Rheinland have shown no visual defects or no other inconsistencies that were found between the secondary seal or PVB film and Silirub® Pro N after exposure to high temperature and humidity (Report No. 12490R-a-89202273).
Due to the large number of edge sealing systems on the market, it is impossible to test the compatibility of all combinations with glazing sealants.
We recommend a compatibility test for both double glass systems and laminated glass systems.
Surfaces should be clean, dry, free of dust and grease.
Porous surfaces in water loaded applications should be primed with Soudal Primer 150. No primer needed for non-porous substrates.
There is no adhesion on PE, PP, PTFE (Teflon®) and bituminous substrates. We recommend a preliminary compatibility test.
Application Method: With a manual or pneumatic caulking gun.
Cleaning: Clean with a Surface Cleaner immediately after use.
Finishing: With a soapy solution or Soudal Finishing Solution before skinning.
Repair: With the same material
Minimum Width for Joints: 5 mm
Maximum Width for Joints: 30 mm
Minimum Depth for Joints: 5 mm
Recommendation Sealing Jobs: Joint Width = 2 x Joint Depth.
Do not use on natural stones like marble, granite etc... as it may cause staining.
Not recommended for use on Polycarbonate (Use Silirub® AL2T)
A total absence of UV can cause a colour change of the sealant.
