Designed for use on sprayed-in-place polyurethane foam, HSS 535 and HSS 540 R2R(TM) one-component coatings are tack-free within 1-2 hr and cure at normal temperatures in 2-6 hr by reacting with moisture in air, forming flexible moisture-free seal. Because coatings are solvent-free, they are environmentally friendly while providing same functionality as petroleum-based roofing materials. Both passed ASTM E108 flame spread test and obtained UL Class A fire rating.
Two New Solvent-Free Silicone Roof Coatings Available from West Development Group
LaGrange, Ohio, (April 29, 2008) - West Development Group (WDG), a leader in sustainable roofing products and practices, recently introduced two new solvent-free silicone roof coatings. HSS 535 and HSS 540 R2R(TM) are both one-component, moisture-curing silicone rubber roof coatings designed for use on sprayed-in-place polyurethane foam.
These coatings can be rolled or spray-applied and touch-up work can be done with a brush or a roller. Ready to use on commercial or industrial roofs, these WDG silicone roof coatings should be applied to a dry, frost-free surface. They are tack-free within one to two hours and cure at normal temperatures in two to six hours by reacting with moisture in the air, forming a durable and flexible moisture-free seal.
HSS 535 and HSS 540 R2R are both a dispersion of silicone rubber. Because they are solvent free, which prevents the release of solvents into the air during application, they are environmentally friendly while providing the same functionality as traditional petroleum-based roofing materials. In addition, HSS 540 contains 20% recycled EPDM material that strengthens the silicone coating's physical properties and keeps tons of old roofing material out of landfills.
Before commercial introduction, the silicone coatings were weather tested in a machine for approximately 10,000 hours to simulate nearly 20 years of exposure to ultraviolet sunlight, moisture, and temperature fluctuation. Following the accelerated weather testing, WDG's silicone coatings continued to provide UV protection and displayed no evidence of degradation such as cracking, hazing, checking, chalking, or loss of film integrity.
HSS 535 and HSS 540 R2R also passed the ASTM E108 flame spread test and obtained Underwriters Laboratories Class A fire rating. Class A roofing systems are effective against severe fire exposures. Other ASTM testing provided ratings for tensile strength, elongation, permeability, and durometer properties. When applied properly, both of these WDG silicone coatings form a seamless, self-flashing seal; resist oxidation, wind-driven rain and snow, as well as ozone; and offer resistance to cracking, peeling, shrinking, or becoming brittle and stiff.
These WDG silicone coatings are a part of WDG's System 14(TM) Total Silicone Roof System, which includes a complete range of products from silicone sheet goods and skylight glazing to silicone sealants and coatings and Spray Polyurethane Foam (SPF) insulation.
