Rosin Modified Phenolic Resin

Rosin Modified Phenolic Resin is the vacuum treated product of esterification of glycerol (or pentaerythritol) with the polycondensate of rosin, phenol (or bisphenol A) and formaldehyde. It is soluble in tar, ester, turpentine oil and similar solvents. Insoluble in alcoholic solvents, partially soluble in petroleum products, mix well with vegetable oils, high softening point, fast drying. Rosin Modified Phenolic Resin can be used for phenolic resin paints (through polymerization with vegetable oils under heat), texture printing inks, the low-cost enhancer in bonding capability for pressure-sensitive adhesive, hot-melt adhesive and other bonding agents.
