Hernon
Silicone Rubber Adhesives/Sealants
Sealing & Bonding

Hernon Silastomer (TM) sealants are high performance, single component, moisture curing RTV (room temperature vulcanizing) silicone gasketing materials that cure into a strong, sihcone rubber that maintains long term durability and flexibility. They have a non--slumping, paste-like consistency which cures when exposed to moisture in the air. Gap filling is excellent with these systems.

Silastorner (TM) adhesives are 100% silicone compounds and are excellent fo weatherproofing. They offer excellent resistance to moisture, temperature extremes, vibration, weathering effects, ozone, ultraviolet radiation, freeze-thaw cycles, and most air borne chemicals. The adhesives can be applied in sub-zero weather with no loss in performance. Fully cured Silastomer (TM) can be used for extended periods at temperatures up to 500*F and for shorter periods, as high as 600*F

The high viscosity of Silastomer (TM) sealants allows application to vertical, horizontal and overhead joints without sagging or running off. The Silastomer (TM) adhesives will adhere to clean metals, glass, most types of wood, silicone resin, vulcanized silicone rubber, natural and synthetic fibers, ceramics, many plastics and other non-porous surfaces.

Silastomer (TM) adhesives begin curing immediately upon contact with air.

Higher humidity accelerates the cure of the Silastomer (TM) adhesives. Parts should be mated and the sealants worked (tooled) before the adhesive surface "skins over," or becomes tack free, normally within 30 minutes at 50% relative humidity and 75*F

Part surfaces should be clean and dry. Best bonding results are obtained by wiping surfaces with solvents. Hernon EF Cleaner (TM) 62 is recommended

When working with plastic substrates verify the suitability of prep solvents prior to application.
