A sealant is an elastic material designed to fill and protect gaps, joints, and cracks in a wide range of construction and industrial applications. Its primary function is to prevent the entry of water, air, dust, insects, and moisture that can cause structural damage over time. Sealants are commonly used in glass installation, window and door frames, wall panels, flooring, roofing, piping systems, and wet areas such as bathrooms and kitchens. With excellent flexibility to accommodate movement caused by temperature changes or vibrations, sealants help maintain airtight and watertight surfaces while reducing the risk of leaks and failures in building joints.
