Polyester dispersant viscosity reduction for adhesives and sealant

This series of additives for two-component polyurethane adhesives are specifically developed for two-component polyurethane (2K PU) systems and are suitable for applications such as two-component polyurethane adhesives, sealants, elastomers, floor coatings, and high-performance industrial systems. The product range covers five major categories—dispersants, anti-sinking thixotropic agents, wetting and levelling agents, defoamers, and tackifiers—providing a comprehensive additive solution for 2K PU formulations. It addresses key challenges including filler and carbon black dispersion, viscosity reduction, anti-settling and sag control, surface wetting on oily substrates, levelling, foam control, and adhesion to metal and non-metal surfaces, without adversely affecting curing speed, activation period, storage stability, or final film properties.
