Profile: Wuzhou Zhongchang Resin Co., Ltd. specializes in the research, development and production of modified rosin resin. Modified rosin pentaerythritol ester provides storage stability and heat oxidation resistance. They dissolve in ester, ketone and aromatic hydrocarbon. Because of good mutual-dissolvability with EVA, SIS, SBS, SBR, NC they increase initial adhesive strength of various kinds of adhesive. These resin series are adhesion resins. Rosin modified phenolic resins are soluble in oil hydrocarbon, aroma, ester, ketone, benzine, benzene, ethyl benzine, spirit and turpentine. These are used in paints, printing inks and adhesives.
