Hot melt adhesive
Other applications: hot melt pressure sensitive adhesive, solvent pressure sensitive adhesive.
Performance and functions of petroleum resin in different industries:
Paint mainly USES high softening point of C9 petroleum resin, DCPD resin, C5/C9 copolymer resin, adding petroleum resin paint can increase the gloss of paint, improve the adhesion, hardness, acid resistance, alkali resistance.
Rubber mainly USES low softening point C5 petroleum resin, C5/C9 copolymer resin and DCPD resin.
This kind of resin and natural rubber colloidal particles have a good mutual solubility, does not have a great impact on the rubber vulcanization process, adding petroleum resin to the rubber can play the role of viscosification, strengthening, softening.
In particular, the addition of C5/C9 copolymer resin can not only increase the adhesive force between the colloidal particles, but also can improve the adhesive force between the colloidal particles and cord, suitable for radial tire and other high requirements of rubber products.
C. Adhesive industry
Petroleum resin has good adhesion, adding petroleum resin in adhesive and pressure sensitive tape can improve the adhesive adhesion force, acid resistance, alkali resistance and water resistance, and can effectively reduce the production cost.
D. ink industry
Ink with petroleum resin, mainly high softening point C9 petroleum resin, DCPD resin.
Adding petroleum resin in the ink can play a color, drying, brightening effect, improve the performance of printing.
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.
At present the petroleum resin road sign paint gradually tends to mainstream, the demand year by year rises.
Resin has a certain unsaturated, can be used for paper glue, plastic modifier.
