Description:
LESTAC-CR Series Coumarone resin is a brown to dark brown granule or flake thermoplastic resin, produced by ethylene and carbon fraction of C9 fractions, coal tar and ethylene re-tar distillates as raw materials.
Applications:
A, Tyre 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 and Ink
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.
Characters:
Good solubility,
Water resistance, Chemical stability of pH,
Mutual solubility, Insulation,
Good adhesion properties, Low thermal conductivity,
