(BITS)

Versatile, injectable & trowelable butyl caulk sealant.
Butyl Injectable Trowelable Sealant

MarMac ElastiSeal® R-900 is a uniquely formulated, one-part butyl adhesive/sealant designed to have excellent resistance to environmental temperature extremes, and acid or alkaline conditions. This creates an excellent moisture resistance barrier and will not attack polystyrene foam.

ElastiSeal® forms a permanent flexible bond to a wide variety of substrates including: brick, concrete, metal, and plastic. It skins over very rapidly through solvent release and cures to a tape-like consistency.

Features & Benefits
  • Extreme temperature range performance
  • Injectable, trowelable, and permanently flexible
  • Easy installation & quick curing
  • Adheres to a wide variety of substrates
  • Saves time & labor
