Pecora 890 NST

Pecora 890NST is a one-part, neutral-curing, ultra low-modulus silicone sealant that will not stain natural stone such as marble and granite and that reacts with atmospheric moisture to form a durable, flexible building sealant. Pecora 890NST performs exceptionally well under dynamic conditions due to its ultra-low modulus, high extension/ compression, recovery properties 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.
