FulaFlex 650FC Hybrid Polymer Fast Cure Sealant & Adhesive

FulaFlex™ 650FC™ Sealant & Adhesive is a high performance, solvent free, moisture curing hybrid polymer construction and industrial adhesive/sealant that provides a non-hazardous alternative to traditional polyurethane adhesive/sealants. It cures to form a seal that is tough, elastic and weatherproof with good chemical resistance. FulaFlex™ 650FC™ Sealant & Adhesive is a high modulus product ideal in bonding applications where differential expansion and contraction are anticipated.
