Soudal Silirub PC Polycarbonate Sealant 300ml Clear

The Soudal Silirub PC Polycarbonate Sealant is a high-performance, neutral-curing silicone sealant engineered for durability and flawless sealing on polycarbonate and other construction materials. It is a low-modulus sealant, meaning it remains permanently elastic after curing, making it ideal for joints with high movement, such as those found in roofing, glazing, and conservatories.

Key features and benefits:

• Specifically for polycarbonate: Unlike other sealants that can cause stress cracking, Silirub PC is specially formulated not to damage non-stressed acrylic or polycarbonate sheeting.

• Highly durable: This sealant is colourfast and highly resistant to UV rays and weathering, ensuring a long-lasting, clear finish that won't yellow or degrade from sun exposure.

• Exceptional adhesion: Offers very good primerless adhesion to a wide variety of building materials, including glass, treated wood, and metal profiles.

• Flexible and resilient: As a low-modulus formula, it can accommodate significant expansion and contraction movements in building joints without cracking or losing its seal.

• Easy to work with: The sealant has a slow skinning time, which provides ample opportunity to tool and achieve a perfect finish before it begins to set. It is also low odour and very easy to apply with a standard caulking gun.

• EC1 PLUS R certified: Certified for very low emissions, contributing to better indoor air quality.

Applications:

• Glazing: Sealing and waterproofing between polycarbonate, glass, and metal or wood frames.

  Conservatory and roof systems:

• Excellent for sealing joints in conservatory roofs, skylights, and other glazing applications where polycarbonate is used.

• Construction joints: Sealing all usual building and expansion joints that are subject to high movement.

Important considerations:
Do not use on natural stone like marble or granite, as it may cause staining. For these applications, consult Soudal's product data sheet for a suitable alternative, such as Silirub MA.
