Features and main uses：
|
|
GC-230 is a solution of isophthalic acid / neopentyl glycol unsaturated polyester in styrene: thixotropic agent has been added, which has good heat resistance, water resistance and cracking resistance. It is suitable for spray forming, and can be used to make waterproof board, heat-resistant bathtub, mould, etc.
