ElastiSeal® R-900 is uniquely formulated one-part, ready-to-use butyl adhesive/sealant which has excellent resistance to environmental temperature extremes and acid/alkaline conditions. ElastiSeal® R-900 forms a permanent flexible bond to a wide variety of substrates including brick, concrete, metals and plastics. It skins over rapidly through solvent release and cures to a tape-like consistency. This adhesive/sealant should not be used with polycarbonates.
