The Northern Paint Industry Research and Design Institute recently developed a new type of aggregated isocyanate curing agent.
This product uses toluene diisocyanate (TDI) as the main raw material, divided into TDI trimer series, modified TDI trimer series and new universal curing agent series. TDI trimer series products have the characteristics of high hardness and good temperature resistance. The suitable solvent system is ester solvent. It can be used for wood decoration paint primers requiring rapid drying and industrial paints with high temperature resistance requirements.
The modified TDI trimer series products are quick drying, high film hardness, low raw material cost, good miscibility with benzene solvents, and can be directly compounded with some alkyd resins and hydroxyl acrylic resins. In addition, when the temperature is low in winter, it can directly replace the general-purpose curing agent. The new general-purpose curing agent series products are light in color, have good miscibility with benzene solvents, low raw material cost, and various properties of the paint film, and are mainly used for high gloss paints.
