GENERAL DESCRIPTION & APPLICATIONS

Rosin Modified Phenolic Resin, a transparent irregular solid, is the vacuum treated product of esterification of glycerol (or pentaerythrite) with the polycondensate of rosin, phenol (or bisphenol A) and formaldehyde. It 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); the resultant paint is fast drying, high in hardness, and shiny; as the low cost enhancer in bonding capability for pressure-sensitive adhesive, hot-melt adhesive, and other bonding agents; as the enhancer in reflectiveness and texture of printing ink.
