        1. YK4501-Low temperature curing agent

          Description

          YK4501 low temperature curing agent is a kind of high acid value resin with relatively high molecular weight. It is mostly linear structure, but also extends through the quaternary carbon structure with a certain proportion of branch chain components. Through careful monomer selection, strict proportion control and precise parameter adjustment, YK4501 low temperature curing agent with unique quality was synthesized. It combines excellent resin stability with excellent coating flexibility and fluidity. A series of deep matte coatings with wide curing temperatures can be synthesized by selecting suitable resins and alkaline catalysts.
