Soudal | Silicone Sealant
Soudal Silirub AL2T is a Premium Grade, Low Modulus, Alcoxy Neutral Cure, 100% Pure Silicone Sealant which is suitable for use on Polycarbonate and other 'difficult' plastic materials. Soudal Silirub AL2T does not cause stress cracking on Polycarbonate unlike many other Silicone Sealants.
Supplied in 300ml Cartridges, available in Clear only.
Soudal Silirub AL2T is a Premium Grade, Low Modulus Alcoxy Neutral Cure 100% Silicone Sealant which is suitable for use on Polycarbonate and other 'difficult' plastic materials.
Soudal Silirub AL2T does not cause stress cracking on Polycarbonate unlike many other Silicone Sealants.
Soudal Silirub AL2T maintains a permanent colour, it's UV Resistant and stays elastic after curing.
Soudal Silirub AL2T has very good adhesion on most traditional construction materials. It is virtually odourless and has primerless adhesion on most building surfaces.

Very good adhesion on many materials
Soudal Silirub AL2T is used for sealing between polycarbonate, treated wooden and metal profiles and glass.
Soudal Silirub AL2T is used for sealing all usual building joints with high movement, and for sealing expansion joints between many different construction materials.
Avoid direct contact between Silirub AL2T Neutral Alcoxy Silicone and the secondary sealant of IGU or the PVB foil in safety glass.
Preferably use Silirub 2 for these types of applications, in accordance with the processing requirements of the DTU39 for carpentry and glazing works, according to the standards and recommendations of the certifiers SNJF, CEKAL.
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
Coverage of any sealant product varies depending on Joint Width and Joint Depth.
Please refer to our Guide on How To Measure The Number of Tubes Required For the Job.
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 suitable for bonding mirrors. Use Soudaseal Mirror for this type of application.
Given the great diversity of possible surfaces it is recommended to do an adhesion test prior to application.
In an acid environment or in a dark room, white silicone can slightly turn yellow. Under the influence of sunlight it will turn back to its initial colour.
When finished with a finishing solution or soapy solution, make sure that the surfaces are not touched by this solution. This will cause the sealant not to adhere to that surface. Therefore we recommend to only dip the finishing tool in this solution.
We strongly recommend not to apply the product in full sunlight as it will dry very fast.
