Hernon® Silastomer 336 is a high performance, single component, acetoxy, ready-to-use silicone. It has a paste-like consistency and cures to a tough, resilient and durable silicone rubber on exposure to moisture in the air. Since it will not flow under its own weight, it can be applied to vertical, horizontal and overhead joints without sagging. It adheres to clean metals, glass, most woods, silicone resin, vulcanized silicone rubber, natural and synthetic fibre, ceramic, many plastics and painted surfaces. It offers excellent resistance to moisture, weathering, vibration, ozone and extreme temperatures; fully cured, it withstands extended periods at up to 204 °C.
