Soudal Silirub HT-N High Temperature Silicone Sealant 310ml | Black

Soudal Silirub HT-N is a premium engineering-grade neutral cure silicone sealant developed for applications requiring exceptional temperature resistance and long-term flexibility.

Its advanced silicone formulation remains permanently elastic after curing while providing excellent adhesion to metals, glass, ceramics, plastics and many common construction materials. Unlike acetoxy silicones, the neutral cure formula is virtually odourless and non-corrosive, making it suitable for sensitive materials and demanding industrial environments.

With temperature resistance up to 280°C, Silirub HT-N is ideal for sealing heating systems, boilers, pipework, ovens, furnaces, chimney flues, pumps and engines where conventional sealants may fail. It also offers excellent resistance to UV exposure, weathering and ageing for long-term performance indoors and outdoors.
