Other applications: hot melt pressure sensitive adhesive, solvent pressure sensitive adhesive.
The performance and function of petroleum resin in different industries:
The paint mainly uses high softening point C9 petroleum resin, DCPD resin, and C5/C9 copolymer resin. The addition of petroleum resin to the paint can increase the gloss of the paint and improve the adhesion, hardness, acid resistance and alkali resistance of the paint film.
Rubber mainly uses low softening point C5 petroleum resin, C5/C9 copolymer resin and DCPD resin. This kind of resin has good mutual solubility with natural rubber particles and has no major influence on the rubber vulcanization process. The addition of petroleum resin to the rubber can increase viscosity, strengthen and soften the rubber. In particular, the addition of C5/C9 copolymer resin can not only increase the adhesion between the rubber particles, but also improve the adhesion between the rubber particles and the cord, which is suitable for high-demand rubber products such as radial tires.
C. Adhesive industry
Petroleum resin has good adhesion. Adding petroleum resin to adhesives and pressure-sensitive tapes can improve the adhesive's adhesion, acid resistance, alkali resistance and water resistance, and can effectively reduce production costs.
D. Ink industry
Petroleum resins for printing inks are mainly high softening point C9 petroleum resins and DCPD resins. The addition of petroleum resin to the ink can achieve the effects of color development, quick drying, brightening, and improving printing performance.
E. Paint industry
Coatings for road signs and road markings. Petroleum resin has good adhesion to concrete or asphalt pavements, and has good abrasion resistance and water resistance. It has good affinity with inorganic substances. It is easy to coat and has good weather resistance. Fast drying, high firmness, and can improve the physical and chemical properties of the layer, and improve the UV resistance and weather resistance. Petroleum resin road marking paint has gradually become mainstream, and the demand has been increasing year by year.
The resin has a certain degree of unsaturation and can be used as a paper sizing agent, plastic modifier, etc.
Petroleum resin should be stored in a ventilated, cool and dry environment. The storage period is generally one year, and it can still be used after one year if the inspection is qualified.
