Description

Rosin, Polymer With Acrylic Acid And Pentaerythritol is a synthetic resin derived from the polymerization of rosin with acrylic acid and pentaerythritol, creating a versatile and modified resin with enhanced properties. This product is engineered to offer superior adhesion, film-forming characteristics, and chemical resistance compared to unmodified rosin. It serves as a critical raw material for formulators in the coatings, adhesives, and ink industries seeking to improve product performance and durability.

Application

• Industrial Coatings: Used as a resinous component in protective and decorative coatings for metal, wood, and plastic, providing excellent gloss, hardness, and water resistance.
• Adhesives & Sealants: Acts as a key tackifier and binder in hot-melt, pressure-sensitive, and structural adhesive formulations, enhancing bond strength and cohesion.
• Printing Inks: Serves as a vital resin in solvent-based and publication gravure inks, contributing to good pigment wetting, print gloss, and rub resistance.
• Polymer Modification: Employed as a modifying agent to improve the compatibility, toughness, and adhesion properties of other polymer systems.
• Paper Sizing: Utilized in internal and surface sizing applications to improve paper's resistance to water and ink penetration.
