Pecora 890FTS and 890FTSTXTR are a one part, neutral curing, ultra low modulus silicone sealants that react with atmospheric moisture to form a durable, flexible building sealant. 890FTS and 890FTS-TXTR will not stain natural stone such as marble and granite and will not contribute to residue run down on non-porous surfaces such as metal and glass curtain wall facades. 890FTS and 890FTSTXTR both perform exceptionally well under dynamic conditions with 890FTS accommodating long-term movement of +100/-50% and 890FTS-TXTR accommodating long-term movement of +50/-50% in properly designed joints. Harsh weather conditions and extreme temperatures have very little effect on the performance of 890FTS and 890FTS-TXTR even after years of exposure. They are also particularly well suited for use in Exterior Insulation Finish Systems (EIFS) because of their proven strong adhesion to all base and top coats and because the ultra-low modulus formulation places minimal stress on the bond line.
