HYLOSIL INSTANT GASKET
Acetoxy curing RTV silicone sealant
Hylosil Instant Gasket is a Room Temperature Vulcanising (RTV) general purpose silicone sealant. Once applied the compound reacts with atmospheric moisture, to form a tough, 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 Instant Gasket is resistant to oil, water and lubricants. It will remain flexible to withstand vibration

Instructions for use
Surface should be clean, dry and free from contamination such as oil or grease. Once applied in Gasket applications, the joint should be assembled without delay.
Care should be taken when applying the compound to ensure any excess product will not foul any internal channels and cause blockages. Any excess uncured product extruded externally can be wiped away with a damp cloth.
When stripping assemblies sealed with, Hylosil Instant Gasket carefully scrape away as much as of the cured product as possible. The remaining compound can be softened and removed using Silicone Sealant Remover.
