Petroleum resin in different industries in the use of performance and role:
A.paint
Paint is mainly used high softening point OF C9 petroleum resin, DCPD resin, C5/C9 copolymer resin, paint added petroleum resin can increase paint gloss, improve paint film adhesion, hardness, acid resistance, alkali resistance.
B.rubber
Rubber mainly uses low softening point C5 petroleum resin, C5/C9 copolymer resin and DCPD resin. This kind of resin and natural rubber rubber particles have good mutual solubility, rubber vulcanization process does not have a big impact, adding petroleum
resin in rubber can play the role of stickiness, reinforcement, softening. In particular, the addition of C5/C9 copolymer resin can not only increase the adhesive force between colloidal particles, but also improve the adhesive force between colloidal particles and cord, which is suitable for high requirements of rubber products such as radial tires.
C. Adhesive industry
Petroleum resin has good adhesion, adding petroleum resin in adhesive and pressure sensitive adhesive tape can improve adhesive adhesion, acid resistance, alkali resistance and water resistance, and can effectively reduce the production cost.
D. ink industry
Printing ink with petroleum resin, mainly high softening point C9 petroleum resin, DCPD resin. The addition of petroleum resin in the ink can play a color, fast drying, brightening effect, improve the printing performance.
E. Coating industry
Road signs and road marking paint with petroleum resin on the concrete or asphalt pavement has good adhesion, and wear resistance and good resistance to water, has a good affinity with the inorganic compound, easy coating, good weather resistance, quick
drying, strong degree is high, and can improve the physical and chemical properties of the layer, improve the uv resistance and weatherability. Petroleum resin road sign paint gradually tends to mainstream, demand increased year by year.
F. other
Resin has a certain unsaturated, can be used for paper adhesive, plastic modification agent.
