It has good solubility, mutual solubility, water resistance, insulation, chemical stability to acid and base, but also has good bonding performance, low thermal conductivity characteristics.
1. Product application field
A, Tires and Rubber: Tires and Rubber are mainly the use of low softening point coumarone resin. It has a good   miscibility with natural rubber particles ,and The rubber vulcanization process is not a big impact, Tire and Rubber cused the resin can play a tackifying, reinforcement, softening effect.
B, Paint: Paint mainly using high softening point coumarone resin, this resin can increase the added paint gloss paint, paint film adhesion, hardness, acid and alkali resistance.
