Neutral Cure Construction Sealant
Polymeric Systems, Inc.
has introduced PSI-641
, a silicone sealant for construction and industrial applications. It is said to offer excellent unprimed adhesion to vinyl, acrylic and most building products without the damaging effects of corrosive by-products . Its lack of annoying odor also makes it suitable for use in enclosed areas.
PSI-641 is a one-part, neutral cure silicone. Its low modulus formulation (high elongation/compression recovery) enables it to compensate for joint movement of +50% with a lasting, flexible seal. The product has all-temperature gunnability. Upon curing, it forms a durable, watertight bond to concrete, masonry, glass, most metals, wood, ceramics and most plastics.
