Rapid-cure, two-component silicone
Bondaflex Technologies, the leading brand of May National Associates Inc., Lakewood, N.J., now includes Bondaflex Silfast 402 and 502: rapid-cure, non-sag, neutral-cure, high-performance silicone sealants/adhesives for structural glazing applications. The versatile, two-component sealants reduce material waste and cost by offering fast-assembly solutions that combine structural glazing and weatherseal applications in one product. Construction applications include structural, impact and conventional glazing; perimeter sealing of windows, doors and skylights; unitized curtain-wall assembly; field replacement glazing; and solar panel installations. Silfast 502 bonds to most substrates without priming, including vinyl, glass, aluminum, tile, fiberglass, plastic, painted surfaces and stone. It is available in cartridges and sausage packs for mockups, field repair and installation of solar panels. Silfast 402 is best suited for those customers who already have 10:1 ratio pumping equipment for in-shop assembly.
