Petroleum resin is a general term for resinous substances synthesized by polymerization of olefins or cycloolefin, by-products of cracked petroleum, or copolymerization with aldehydes, aromatics, terpenes, etc.
It is characterized by low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance.
Soluble in aliphatic hydrocarbons and chlorinated hydrocarbons, insoluble in lower alcohols and ketones.
Mainly used in the paint industry, light-colored petroleum resins are used in the manufacture of oil varnishes to improve gloss and adhesion.
Petroleum resin can also be generally used in the rubber industry, with a low softening point of resin as plasticizer, with a high softening point of resin to improve the hardness of synthetic rubber.
Also used to prepare hot melt adhesive, traffic sign paint, printing ink and paper hydrophobic agent.
Today to introduce the application of petroleum resin in the ink industry
Petroleum resin is widely used in the field of printing ink. Petroleum resin is a product refined from petrochemical industry. Its main function is to serve various functions such as high-temperature lubrication.
The application of petroleum resin in the field of ink has a long history, the first has more than 20 years of history, mainly to increase the elasticity of ink, viscosity, increase and decrease the durability of ink, is an indispensable part of the ink industry.
