Hylosil 302 Black RTV silicone sealant 300ml cartridge

Hylosil 302 Silicone Sealant is a Room Temperature Vulcanising (RTV) general purpose silicone sealant. Once applied the compound reacts with atmospheric moisture to form a tough and durable, rubber seal. It has excellent adhesion to metals, glass, ceramics and plastics. The compound has large gap filling properties which makes it ideal for application to non-machined surfaces and even as cast surfaces.
Hylosil 302 Silicone Sealant is resistant to oil, water and lubricants. It will remain flexible to withstand vibration.
