Pecora 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.
