Description:

Pecora 890NST Ultra-Low Modulus Silicone Sealant, #890-046, is a one-part, neutral-curing, ultra low-modulus silicone sealant that will not stain natural stone such as marble and granite and reacts with atmospheric moisture to form a durable, flexible building sealant. Pecora 890NST Silicone Sealant 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.

Applications:

• Pecora 890NST Silicone Sealant is designed primarily for sealing expansion and control joints in precast concrete panels, architechtural and natural stone, metal curtainwalls, perimeter sealing of doors and windows, Exterior Insulation Finish Systems (EIFS) and numerous other areas requiring a high-performance sealant.
• Pecora 890NST adheres tenaciously to concrete, natural stones, masonry, steel, fluoropolymer painted and powder coated aluminum, wood, vinyl and many other plastics.
