Quick links

GlasSil is a one-component, ketoxime-cure silicone sealant that cures at room temperature to form a durable, high-modulus silicone rubber seal.

GlasSil is designed for applications requiring long-term flexibility, weather resistance, and compatibility with a variety of building materials. It adheres to substrates such as glass, metal, concrete, ceramic, and painted surfaces when proper surface preparation and priming practices are followed.

Its non-sag paste consistency allows smooth application and tooling across a broad temperature range. Once cured, the sealant maintains elasticity and resistance to water, temperature variation, and exterior exposure.

Its neutral cure chemistry minimizes the odor commonly associated with acetoxy silicones and is suitable for a wide range of glazing and construction sealing applications.

Recommended for:

  • Glass-to-glass and glass-to-metal sealing
  • Prefabricated housing and modular construction
  • Freight containers and cold storage room sealing
  • Interior perimeter joints and general glazing work
Performance
