Bostik Findley Introduces New Bostik® GPS 1 Moisture Cure, General Purpose/Roof Sealant
MIDDLETON, Mass., June 4, 2004 - Bostik Findley, Inc., a worldwide manufacturer and supplier of adhesives and sealants, is introducing Bostik® GPS1: a new, construction-grade, one component moisture cure sealant that offers economical yet high performance sealing qualities.
Engineered for superior adhesion to various roofing substrates as well as for general purpose sealing of dissimilar substrates, GPS1 is an elastomeric urethane sealant specifically formulated with low solvent content and low odor for a wide variety of interior or exterior construction applications. Its tenacious adhesion to roofing substrates such as Kynar, anodized aluminum, copper and stainless steel make it a superior sealant for roof penetrations, soffit or fascia applications or sealing dissimilar building materials. Its high solids content and elastomeric quality provide long-lasting seals that will not shrink or become brittle with prolonged exposure to weather extremes or ultraviolet rays.
Compared to solvent based products, GPS1 is a highly economical, moisture reactive sealant that features less than 4-percent VOC content, CARB and SCAQMD compliance, lower odor and a PVC-free formulation to make it highly suitable for geographically unrestricted, multi-environment usage. Its non-sag formula provides excellent performance for critical vertical applications. Permanently elastic within a temperature range of -40° F to 150° F, Bostik GPS1 has an approximate 60-minute skin-time. After full cure, the sealant provides very good UV radiation resistance, as well as outstanding resistance to extreme and/or harsh weather conditions. Typical physical properties include: a tensile strength of 135 psi; an elongation rating of 550 percent; and a 35-40 Shore A hardness value. Additionally, GPS1 has a 12-month shelf life.
