PU Hardener

The PU Hardener acts as a reactive component that boosts crosslinking efficiency within polyurethane matrices. It enhances polymer cohesion and film integrity, shortening drying times. Depending on formulation, it can be aromatic or aliphatic, each with distinct performance traits. It maintains transparency and prevents yellowing during aging. Suitable for PU coatings, sealants, and adhesives, it ensures uniform curing and superior durability.
