SINOMER ® UVU6229 PCD-UA is a difunctional PUA resin synthesized from premium polycarbonate diol, featuring 100% reactive content and high viscosity. It demonstrates excellent weatherability and flexibility. When used in UV plastic spray coatings, it effectively adjusts the hardness and flexibility of the formulation, balancing properties such as resistance to boiling water, salt spray, high and low temperatures, and thermal cycling. In UV printing varnishes and inks, it serves as the main PUA component, providing comprehensive solvent resistance, flexibility, non-yellowing properties, and fast UV curing activity.
