Weathersealing of aluminium glazing systems, curtain walling and facade panels.
Sealing of roofline and drainage systems.
Can be used in direct contact with all types of glass, except self cleaning types.
Bedding of double glazed sealed units in wet glazing applications.
Sealing of expansion and movement joints in construction.
Roofing seals including lead, roofing slates and fibre-cement.

HVAC Ducting, pipework and drainage joints.
General maintenance of sealing cars, caravans, mobile homes and boats.
Tests carried out in laboratories show that Silirub 2 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 2 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.
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.
