Product description: C9 Aromatic Petroleum Resin for hot melt Wide compatiblity with different polymersand resins light color They a clear yellowwish resins, soluble in most industrial solvents, and particularly in aromatic and aliphatic ones. The major application are including paitns, adhesive, printing ink, rubber and asphalt, etc. 1.Product Introduction C9 Hydrocarbon Resin is a kind of Aromatic Hydrocarbon resin produced by C9 fraction,by products of petroleum cracking,through pretreatment, polymerization and distillation.It isn't a high polymer but a low polymer with the molecular weight between 300-3000.Featared 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 resins are not used independently,but have to be used together with other kinds of resins as promoters, adjusting agents and modifiers. 2.Application A.Paints Paints mainly use C9 Hydrocarbon Resin with high softening points,C9 Hydrocarbon Resin added to paints can increase the final finishes of paints,the adhesiveness of paint films and the hardness.Resistance to acid and alkaline. B.Rubbers Mainly use C9 Hydrocarbon Resin with low softening points,the resin has very good mutual solubilities with natural rubber particles,No affect to the sulphurization of rubber. C.Adhesives The resins have very good adhesiveness,they can increase the adhesiveness of adhesives, resistance to acid,alkaline and water.Subsequently they will reduce the production cost. D.printing inks Usually,C9 Hydrocarbon Resin which have high softening point are used for printing inks,they have color spreading,fast dry and brightening effects and will increase the printing property. E.Others C9 Hydrocarbon Resin has certain unsaturation property and can be used as paper glutting agents,plastic modifiers etc. 3.The testing method of hydrocarbon resins Softening point:GB2294 coal asphalt softening point determination method Color method:GB12007,Ga.(toluene/resin=1/1) Acid value:GB2895 unsaturated polyester resin determination method Br.value(iodine value) indicator titration method Ash content GB2295 coal asphalt ash content determination method
