About this product
890NST is a one part, neutral curing, ultra low modulus silicone sealant that reacts with atmospheric moisture to form a durable, flexible building sealant. 890NST 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. Pecora 890NST performs exceptionally well under dynamic conditions due to its ultra-low modulus, high extension/compression, recovery proper ties and strong adhesion to most building materials and accommodates long-term movement of +100/-50% in properly designed joints. Harsh weather conditions, rain, sleet, snow, sunlight and extreme temperatures, high ozone concentrations and/or exposure to intense ultra violet rays have very little effect on the ultimate performance of Pecora 890NST even after years of such exposure. Pecora 890NST is particularly well suited for use in Exterior Insulation Finish Systems (EIFS) because of its proven strong adhesion to all base and top coats and because its ultra-low modulus formulation places minimal stress on the bond line. Additionally, Pecora 890NST is avail able in many of the more popular EIFS colors.
