Petroleum resins different from that of General resins, cannot be used alone, usually mixed with other materials as a blend to improve product performance.
Petroleum resins are mainly used in the following aspects:
(1) application of coatings industry. In the paint industry, petroleum resin can be combined with other resins, wholly or partly replace high resin, in order to reduce costs, improve product gloss, hardness, water resistance, stability, and chemical resistance and other performance objectives. For formulations such as phenolic varnishes, C9 petroleum resin by replacing calcium Rosin modified phenolic resin and rosin resin, the product continues to meet the standards of novolac phenolic aldehyde enamel, while C9 petroleum resin, Rosin modified phenolic resins cost less than the cost of 1/4, thus greatly reducing costs. Added to the epoxy resin, polyurethane Matt alicyclic petroleum resin, can improve the hardness of the product, a tortuous trial, water temperature, weather and so on.
(2) application of adhesives. Adhesives, petroleum resin plays mainly to provide bonding function. Viscosity and the main component for natural rubber, synthetic rubber, polyolefin, polypropylene acid vinegar, ethylene vinyl acetate copolymer and other kind of basic polymers, addition of petroleum resin, adhesion of the polymer can improve stability, creep resistance, heat resistance and other properties. Petroleum resin with Thermoplastic Elastomer SBS block copolymer in toluene in mixed solvent of hexane to mix it up, made sticky mixtures can be used to make pressure-sensitive adhesive tape pressure sensitive adhesive.
