Soudal Silirub PC Neutral Silicone Sealant

(300ml EU3 Cartridge)

Stress-Free Polycarbonate & Glazing Sealant

Neutral-cure alkoxy silicone sealant developed specifically for polycarbonate, with excellent compatibility across double-glazing edge seals, PVB films, and acrylics such as Plexiglas. As it cures, it releases alcohol by-products that do not cause stress cracking in sensitive plastics – making it ideal for conservatory roofs, glazing, and high-movement construction joints. Good UV resistance and permanent elasticity provide a durable, weatherproof seal in demanding outdoor applications.

Conforming to ISO 11600 F25LM and G25LM, this low-modulus formula accommodates joint movement of up to ±25%. It provides very good adhesion to glass, metal, wood, concrete, PVC, and other common substrates. Its slow skinning time (approximately 10–20 minutes, depending on conditions) gives ample time for tooling, while EC1 Plus R certification ensures very low emissions and low odour during application.

Features & Benefits

  • Plastic-Safe - won’t cause stress cracking in polycarbonate or Plexiglas
  • Glazing-Friendly - compatible with most double-glazing edge seals and PVB films
  • Non-Corrosive - neutral cure won’t attack metal frames or fixings
  • Weather Resistant - colourfast and UV resistant for long-lasting outdoor sealing
  • Highly Flexible - low-modulus formulation allows movement up to ±25%
  • Easy Tooling - slow skinning gives you time to work the joint
  • Strong Adhesion - bonds securely to glass, metal, wood, concrete, PVC, and more
  • Low Emissions - certified for very low emissions and low odour

Did you know? Common oxime silicones release MEKO (Methyl Ethyl Ketoxime) as they cure, which can act as a plasticizer and contribute to stress cracking in plastics. Silirub PC utilizes an alkoxy curing system that releases alcohol as it reacts with air moisture, making it ideal for use with polycarbonate and acrylics.
