Isophthalic acid resin

Isophthalic acid resin is a liquid polyester resin. The properties of liquid polyester resin, including the cured product, are primarily determined by the types and quantities of raw materials used to make polyester. Those raw materials are glycols and acids. In the case of isophthalic acid resins, the type of acid used is isophthalic acid. These resins have higher chemical resistance and better mechanical properties and are more resistant to heat compared to orthophthalic acid resins. In addition, these resins are especially resistant to water and ammonia.
