Trowelable or caulk tube skinning butyl sealant
Butyl Injectable Trowelable Sealant
MarMac BITS is an uniquely formulated one-part butyl adhesive/sealant that is designed to have excellent resistance to environmental temperature extremes, and acid or alkaline conditions. This creates excellent moisture resistance and will not attack polystyrene foam.
MarMac BITS forms a permanent flexible bond to a wide variety of substrates including brick, concrete, metals, and plastics. It skins over very rapidly through solvent release and cures to a tape-like consistency.
