Pecora 890NST Classic Bronze is a one-part, neutral-curing, ultra-low-modulus silicone sealant that will not stain natural stone such as marble and granite. It reacts with atmospheric moisture to form a durable and flexible building sealant.
***12 Sausages per case. Individual sausages are available for purchase. This item is stocked only in Minnesota***
Performs exceptionally well under dynamic conditions due to its ultra-low modulus, high extension/compression, recovery properties and strong adhesion to most building materials. Accommodates long-term movement of +100-50% in properly designed joints. Harsh weather conditions such as rain, sleet, snow, sunlight and extreme temperatures, high ozone and concentrations and/or exposure to intense ultraviolet rays have very little effect on the ultimate performance of 890 NST, even after years of such exposure.
