Hot melt adhesive
Other applications: hot melt pressure sensitive adhesives, solvent pressure sensitive adhesives.
Performance and function of petroleum resin in different industries:
A, paint
C9 petroleum resin, DCPD resin and C5/C9 copolymer resin with high softening point are mainly used in paint. Adding petroleum resin to paint can increase gloss, adhesion, hardness, acid resistance and alkali resistance of 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 particles have good mutual solubility, and have no great influence on the vulcanization process of rubber. The addition of petroleum resin in rubber can play the role of tackifying, reinforcing and softening. Especially the addition of C5/C9 copolymer resin can not only increase the adhesion between rubber particles, but also improve the adhesion between rubber particles and cord. It 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 adhesiveness, acid resistance, alkali resistance and water resistance of adhesives, and can effectively reduce production costs.
D. Ink Industry
Petroleum resins for inks are mainly high softening point C9 petroleum resins and DCPD resins. The addition of petroleum resin in ink can play the role of color development, fast drying, brightening and improving printing performance.
E. Coatings Industry
Coatings for road signs and road marking, petroleum resin has good adhesion to concrete or asphalt pavement, good wear resistance and water resistance, good affinity with inorganic substances, easy coating, good weather resistance, fast drying, high firmness, and can improve the physical and chemical properties of the layer, improve the ultraviolet and weather resistance. At present, petroleum resin road marking paint is gradually becoming the mainstream, and the demand is increasing year by year.
F, others
The resin has certain unsaturation and can be used as paper sizing agent and plastic modifier.
5. Petroleum resins are non-dangerous goods. During transportation, they should be protected from sunshine and rain. They should not be transported with spontaneous combustion, strong oxidant and strong acid.
Petroleum resin should be stored in a ventilated, cool and dry environment. The storage period is usually one year, and it can still be used after one year if it is qualified.
