Description:
LESTAC-P Seires Light to Yellow Color C9 aromatic petroleum resin is a kind of internal plasticizing resin produced by C9 fraction, by- products of petroleum cracking, through pretreatment, catalysis or thermal polymerization and distillation, so named because they are generally polymers of nine-carbon aromatic monomers. Usually the colors of thermal polymerized C9 copolymerized resin are darker than cold-polymerization. Application: A. Paint Industries Paints mainly use C9 petroleum resin with high softening points, C9 petroleum resin can increase the gloss of paint and improve the adhesion and the hardness, anti-acid, alkaline- resistance, water-resistance. B. Adhesive C9 petroleum resins have very good adhesiveness, they can increase the adhesion of adhesives especially for hot-melt adhesive, pressure-sensitive adhesive, coating, etc. C. Rubber and Tyre Mainly use C9 petroleum resin with low softening point, these C9 resin has very good mutual solubilities with natural rubber particles, non-affect to the sulphurization of rubber. D. Printing Ink Usually use C9 petroleum resin with high softening point, they have color spreading, fast dry and brightening effects and will increase the printing properties. E. Other C9 Petroleum resin has certain unsaturation property and can be used as paper glutting agents, plastic modifiers etc. Characters: Yellow color to brown color, Distinguished initial adhesion, Water-resistance, Low volatility, Low acid value, Good adhesion, Good viscosity, Good solubilities with vaious polymers,
