1 Application in coatings: C9 petroleum resin can replace “rosin modified phenolic resin” and “rosin calcium ester” in equal amounts to make C9 petroleum resin varnish and various enamel paints, and its performance can reach “F01-1” Standards for "novolak" and "F04-1 phenolic enamel". The cost of C9 petroleum resin is only 24.8% of “rosin modified phenolic resin”, and its application in the coating industry has broad development prospects.
2 Application in rubber products: C9 petroleum resin can replace Gumalon resin (as reinforcing softener to reduce product cost), oil, softening heavy oil and other rubber additives, and can be applied to oil seal rubber and water tank elbow rubber compound. Heat resistant, acid resistant, alkali resistant and other rubber compounds. Tests show that C9 petroleum resin has better viscosity than coumarone resin, and can increase the amount of reclaimed rubber and filler in the rubber compound formulation, reduce the amount of natural rubber, and reduce the rubber product under the premise of ensuring product performance. cost.
3 Application in the binder: C9 petroleum resin and an equal amount of natural rubber are mixed in a solvent to obtain a pressure-sensitive adhesive, which is applied to a substrate such as kraft paper, cloth or cellophane. Can be used as a bond. Natural rubber and C9 petroleum resin do not have cohesive properties when used alone, and if they are mixed, the adhesion of rubber is clearly exhibited.
Therefore: C9 petroleum resin can be used as a functional additive for natural rubber. It is excellent for use in hot melt adhesives and EVA: it can be used in inks to make high-middle and low-grade inks. It has good toughening effect in PVC enamel: it can be used in paint to improve the fullness of paint film. Degree is gloss, and can also be applied to oilfield additives.
