Description

Pecora 890 Sausage NST One-Part High Performance Silicone Sealant. Contact us

Pecora 890NST 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. It adheres tenaciously to concrete, natural stones, masonry, steel, fluoropolymer painted and powder coated aluminum, wood, vinyl and many other plastics, generally without need for a primer, and performs equally well in new or remedial construction.

Pecora 890 is a one-part, neutral-cur- ing, 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 build- ing sealant. Pecora 890 performs exceptionally well under dynamic condi- tions 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.

Surface Preparation:                                                                                                                                                                       Clean all joints and glazing areas by removal of foreign matter and contaminants such as oil, dust, grease, frost, water,surface dirt, old sealants or glazing compounds and any protective coating. Porous substrates and precast concrete panels using form release agents other than polyethylene film should be cleaned by grinding,saw cutting, blast cleaning (water or sand), mechanical abrading or a combination of these methods which will provide a sound, clean and dry surface for sealant application. Dust, loose particles, etc.should be blown out of joints with oil-free compressed air or vacuum cleaned. Metal, glass and plastic surfaces should be cleaned by solvent procedure or by mechanical means. Soap or detergent and water cleaning  treatments are not recommended. Cleaning of all surfaces should be done on the same day on which the sealant is applied.
