Wacker HA Silicone Sealant is a high-temperature resistant, acetoxy-curing silicone sealant designed for sealing applications exposed to elevated temperatures. It is a one-component silicone sealant that cures at room temperature under the action of atmospheric moisture, forming a permanently flexible and heat-resistant silicone rubber.

This sealant is supplied in a 300 ml cartridge and is commonly available in red colour, making it easily identifiable for high-temperature applications. Wacker HA provides strong adhesion to metal, glass, ceramic tiles, and heat-exposed surfaces, ensuring reliable sealing performance where standard silicone sealants are not suitable. Its non-sag formulation allows clean application on both vertical and horizontal joints without slumping.

Wacker HA Silicone Sealant is engineered to maintain flexibility and sealing integrity even when exposed to continuous high temperatures. After curing, the sealant resists cracking, shrinkage, and ageing caused by heat exposure, making it suitable for industrial, automotive, and construction-related thermal sealing applications.
