Description

Rosin, Polymer With Formaldehyde And Phenol CAS NO 67700-45-2 is a synthetic resin derived from the polymerization of rosin with formaldehyde and phenol, creating a modified phenolic resin with enhanced properties. This product is valued for its excellent tackifying, adhesive, and film-forming characteristics, making it a crucial component in industrial formulations. It is primarily used by manufacturers in the adhesives, coatings, printing inks, and rubber industries seeking to improve product performance and durability.

Application

• Adhesive Formulations: Acts as a key tackifier and modifier in hot-melt, pressure-sensitive, and structural adhesives.
• Industrial Coatings: Used in protective and decorative coatings to enhance gloss, hardness, and water resistance.
• Printing Inks: Serves as a resinous binder in gravure and flexographic inks, improving pigment wetting and print quality.
• Rubber Compounding: Functions as a processing aid and reinforcing agent to improve tack and tensile strength.
• Foundry Core Binders: Utilized in sand casting processes as a binding agent for mold and core sands.
• Paper Sizing: Enhances the water resistance and surface strength of paper and paperboard.
