ICO Caulk™ is a two-part, 100% solids semi-rigid epoxy caulk. It has excellent adhesion to concrete, metal, wood, brick and tile, on both damp and dry surfaces. It is USDA-approved, has virtually no odor and no toxic by products. ICO Caulk™has good chemical resistance to most common cleaners, battery acids, fuel oils, and some solvents. As a semi-rigid epoxy, with a Shore A Hardness of 85 and a tensile elongation of 36%, ICO Caulk™ will better withstand heavy traffic, compared to a flexible urethane or silicone caulk. It dries to a glossy easy-to-clean finish. ICO Caulk™ is available in a pourable or gun grade in either a regular cure or fast cure (“FC”) grade in one gallon or 4 gallon kits in all our standard colors.
ICO Caulk™is a durable expansion or control joint material for inside applications where limited movement is expected. It possesses significantly higher tensile strength and bond strengths than elastomerics and thus, is a far better joint material under heavier wear conditions. ICO Caulk™ is particularly effective in damp environments, such as food process plants. For new concrete and for moving joints, our ICO Lastic Gun Grade is recommended. For outside applications, use ICO Caulk X.
