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
