Description
Chem-Calk 1250 is an oxime/neutral-cure, high-performance silicone sealant featuring an optimized modulus. It is a low-odor formulation that offers superior adhesion to a wide variety of construction and industrial substrates, including concrete and masonry, most metals, plastics, and wood.
Chem-Calk 1250 is tough yet flexible, and offers fast green strength build and a fast cure. This tear-resistant sealant retains elastomeric properties from -62°F to 350°F, (-52°C to 176°C). Chem-Calk 1250 demonstrates superb hydrolytic stability. Unlike acetoxy-cure silicones, its curing mechanism is non-corrosive and therefore does not compromise most substrates.
