Description

Rosin, Polymer With Diethylene Glycol, Maleicanhydride, Tall-Oil Rosin And Triethylene Glycol CAS NO 90091-77-3 is a complex, modified rosin ester polymer designed for high-performance industrial applications. This specialized resin offers enhanced thermal stability and compatibility, making it a critical component in formulations requiring durable adhesion and film formation. It is primarily utilized by manufacturers in the adhesives, coatings, and ink industries seeking reliable and consistent raw materials for demanding production environments.

Application

• Hot-Melt Adhesives (HMA): Acts as a key tackifier and modifier, improving adhesion, viscosity control, and thermal stability.
• Pressure-Sensitive Adhesives (PSA): Enhances tack, peel strength, and shear resistance in tapes and label formulations.
• Industrial and Protective Coatings: Used as a resin modifier to improve gloss, hardness, and water resistance in coating systems.
• Printing Inks: Serves as a resin component to promote pigment wetting, gloss, and rub resistance in various ink types.
• Polymer Modification: Functions as a compatibilizer and processing aid in rubber and plastic compounding.
• Sealants and Caulks: Imparts flexibility, adhesion, and durability to non-hardening sealant formulations.
