A. paint: the paint mainly USES C9 petroleum resin, DCPD resin and C5/C9 copolymer resin with high softening point. The addition of petroleum resin into the paint can increase the gloss of the paint and improve the adhesion, hardness, acid resistance and alkali resistance of the paint film.
B. Rubber: rubber mainly USES C5 petroleum resin with low softening point, C5/C9 copolymer resin and DCPD resin.
This kind of resin and natural rubber colloidal particles have good mutual solubility, has no great influence on the vulcanization process of rubber, adding petroleum resin in rubber can play the role of increasing viscosity, strengthening and softening.
Especially the addition of C5/C9 copolymer resin, not only can increase the adhesive force between colloidal particles, but also can improve the adhesive force between colloidal particles and cord, suitable for radial tire and other high requirements of rubber products.
C. Adhesives industry: petroleum resin has good adhesion. Adding petroleum resin into adhesives and pressure-sensitive tapes can improve adhesion force, acid resistance, alkali resistance and water resistance of adhesives, and effectively reduce production costs.
D. Ink industry: petroleum resin for ink, mainly C9 petroleum resin with high softening point and DCPD resin.
The addition of petroleum resin in ink can play a role in color display, rapid drying, brightening effect, improve the printing performance.
E, others: resin has a certain unsaturated, can be used for paper adhesive, plastic modifier.
