It is suitable for waterborne resin systems, such as waterborne acrylic and waterborne polyurethane, to improve the adhesion, strength and hardness of coatings.
It can be made into a single-component system with resin, and the performance of the coating depends on the treatment process, the amount of crosslinking agent and Hydroxyl value of the system.
DB-W can be used in acidic, alkaline and neutral aqueous systems, and the addition amount is usually 3-5% of the system
The treatment temperature should be higher than 110℃. The higher the temperature, the shorter the treatment time and the faster the curing speed.
