Architectural weatherproofing supplier Pecora has added AVB Silicone, a one-part silicone sealant, to its commercial construction line.

AVB Silicone is formulated for primerless use on transition seals, according to Pecora.

The product offers "exceptional adhesion" between dissimilar materials in air and vapor barrier systems, such as high-density polyethylene peel-and-stick laminates, liquid-applied weather barriers, building wraps and termination/transition seals, and other typical building materials, the company says.

Features and Availability

Pecora AVB Silicone is durable in all weather conditions and is compatible with natural stones and other porous surfaces susceptible to staining or silicone fluid migration, according to the manufacturer.

The company says the 100% silicone sealant provides primerless adhesion to most common building materials.

With a +/-25 percent movement capability, AVB Silicone provides the "dynamic joint movement" required for highly efficient and innovative structures, the company says.

The professional system is available in 20 oz. (592ml) sausages.

Founded in 1862, Harleysville, PA-based Pecora produces silicone, urethane and latex sealants for the commercial construction market.
