Description

  • Dowsil 791 weatherproofing silicone sealant 310ml is a high‑performance, one‑part, neutral‑curing silicone designed for long‑term weather sealing applications across commercial, industrial and residential environments. This dowsil 791 weatherproofing silicone sealant 310ml formulation is engineered as a low‑modulus product, allowing it to cure into a flexible rubber that accommodates significant joint movement without cracking or losing adhesion. Its neutral‑cure chemistry ensures compatibility with a wide range of sensitive substrates, including coated glass, galvanised steel, copper, masonry and other materials commonly found in façade and glazing systems.
  • Dowsil 791 offers excellent adhesion to glass, metal, concrete and other non‑porous surfaces, making it suitable for perimeter joints, expansion joints, connection joints and general weather sealing tasks. Once cured, it provides a durable, UV‑resistant and weather‑resistant seal that maintains elasticity even under extreme temperature variations and long‑term environmental exposure. The product is also paintable, allowing installers to achieve a seamless finish when integrating the sealant into architectural designs.
  • Product Benefits:
    • Ideal for expansion, connection, perimeter and other movement joints
    • Neutral cure – suitable for coated glass, galvanised steel, copper, masonry and more
    • Low modulus sealant according to ISO standards; medium modulus according to ASTM standards
    • Extension/compression movement capability of up to ±50% of the original joint width
  • Overall, this dowsil 791 weatherproofing silicone sealant 310ml provides a reliable, flexible and long‑lasting sealing solution for demanding weatherproofing applications where movement capability, substrate compatibility and durability are essential.
