Original Press Release:
Bostik Introduces Chem-Calk 1250 Series
Middleton, Mass. - Bostik Inc.'s Construction & Industrial (C&I) Business Unit is proud to introduce its Chem-Calk® 1250 Series - high-performance, oxime/neutral cure silicone sealants that retain elastomeric properties from -52º C to 176º C. Chem-Calk 1250 indoor/outdoor silicone sealants deliver superior adhesion to most construction and industrial materials. The non-corrosive formulations have excellent UV resistance and low odor, and feature fast green-strength build and rapid cure.
"Unlike most commodity silicones in the marketplace, our Chem-Calk 1250 Series are not highly extended," says James Downing, Bostik C&I Market Manager - Construction Products. "Because they're not diluted, Chem-Calk 1250 silicone sealants can couple unmatched elastomeric properties with great grab. They routinely outperform the competition - inside and outside - across a wide range of temperatures and over an array of substrates."
Chem-Calk 1250 sealants meet: ASTM C920; TT-S-00230C; TT-S-001543A;
AAMA 808, 803 and 802; and MIL-A-46106 standards. They also are CARB and SCAQMD compliant.
Bostik's Chem-Calk 1250 sealants come in 10.3-ounce cartridges. The sealants are available immediately in clear, white, aluminum, black, bronze and gray color formulations.
Kurt Zintner, Bostik Technical Service Manager - Construction Sealants & Adhesives, says the innovative silicone sealants feature extended service life and help reduce installation fatigue.
"Chem-Calk 1250 silicone sealants are ready to use, easy to gun, and quick to clean up," Zintner adds. "These sealants demonstrate superb hydrolytic stability and, unlike acetoxy-cure silicones, their curing mechanism is not corrosive - so they typically will not compromise the substrate - be it concrete, masonry, metal, plastic or wood."
