Hapsil 360™ is a high tear strength, tin-catalyzed RTV-2 silicone rubber, which was designed for casting Hapco's wide variety of rigid and flexible polyurethane resins.
Hapsil 360™ is not sensitive to inhibition, meaning it will cure at room temperature over virtually any surface. Hapsil 360™ works well with clear and colorless casting resins that typically exhibit a sticky, uncured surface when cast against most silicones. It is easy to mix and de-gas, and cures with minimal shrinkage.
Hapsil 360™ can be used with or without a release agent and is ideal for any application where a strong flexible rubber is required.
