1Kpolyuretaanitiivisteet
1K polyuretaanitiivisteet refer to a category of sealants that are based on polyurethane chemistry and require only one component for curing. Unlike two-component systems, these sealants do not need to be mixed before application, simplifying the process for the end-user. The curing mechanism is typically initiated by moisture present in the air or on the substrate. As moisture interacts with the polyurethane prepolymer, it triggers a chemical reaction that causes the sealant to cross-link and harden, forming a durable and flexible seal.
These types of sealants are known for their excellent adhesion to a wide range of building materials,
1K polyuretaanitiivisteet generally offer good resistance to weathering, UV radiation, and chemicals, contributing to their longevity
