Petroleum Resin(hydrocarbon resin) is a kind of low molecular weight amorphous polymers. The main applications are adhesives(hot melt adhesives, solvent base adhesives, emulsion adhesives), inks(mainly offset printing inks), paints and varnishes(road marking paints, Aluminum Paints, anticorrosion paints), rubbers and tyres. In adhesives, resins are used to generate tack and specific adhesion. Mostly they are used together with larger polymers, like EVA and rubbers, which form the backbone of the adhesive and thus generate cohesion. Formulators use resins to create the best balance between adhesion and cohesion.
