FAQ

What are the key advantages of Propylene glycol monobutyl ether in water-based coating formulations?

Propylene glycol monobutyl ether has excellent coalescing performance and moderate volatility in water-based coatings. It can effectively reduce the minimum film-forming temperature of the coating system, ensure the uniform film-forming of the coating on different substrates, and improve the adhesion, water resistance and scratch resistance of the coating film. At the same time, its good miscibility with water can ensure the long-term stability of the coating formulation without phase separation.
