FulaFlex™ 625 is a high performance, solvent free, moisture curing hybrid polymer construction sealant that provides a non-hazardous alternative to traditional polyurethane construction sealants. It cures to form a seal that is tough, elastic and weatherproof with good chemical resistance. FulaFlex™ 625 is a low modulus product ideal for sealing joints where high joint movement is anticipated.
