Petroleum resin 2 Petroleum resin is a kind of thermal plasticizing resin produced by c5,c9 fraction, by-products of petroleum cracking, through pretreatment, polymerization and distillation. It isn't a high polymer bat a low polymer with the molecular weight between 300-3000. Featured by acid value, easy mutual solubilities, resistant to water, resistant to ethanol and chemicals. It has the chemical stabilizing property to acid and alkaline, viscosity adjusting and thermal stabilizing. Generally, the petroleum resins are not used independently, but have to be used together with other kinds of resins as promoters, adjusting agents and modifiers. Application Rubber:Tackifier, reinforcing resistance, cut resistance, tensile resistance, abrasion resistance, increased toughness, increased hardness Paint:Enhance the luster, improved adhesion, increased hardness and drying rate, resistant to water, acid and alkali Ink: Control viscosity, increase gloss, hardness and pigment connectivity, enhance the release rate of solvent Coating:Increase gloss, improved adhesion and drying rate, resistant to water, acid, alkali and electricity Others: Signs paint, paper glue, concrete additives, plastics modification agent
