Vulkem 45SSL is a high-performance, durable, semi-self-leveling polyurethane sealant designed for expansion joints in horizontal applications. Its advanced polymer technology allows for exceptional adhesion to damp or green concrete without outgassing, making it ideal for use on fresh concrete surfaces, offering superior UV resistance and wear protection, making it suitable for high-traffic areas. It can withstand continuous immersion in non-chlorinated water and is resistant to jet fuel, ensuring reliability in challenging environments. With its low modulus and easy application using conventional caulking equipment, Vulkem 45SSL provides a long-lasting, flexible seal for horizontal surfaces with slopes up to 6%.
