Description

Rosin, Polymd., Polymer With Maleic Anhydride, Phthalic Anhydride, Tall Oil, Tetrahydroabietyl Alc. And Trimethylolethane CAS NO 154862-02-9 is a high-performance, multi-component synthetic resin derived from modified rosin and other key monomers. This engineered polymer is valued for its excellent adhesion, film-forming properties, and chemical resistance, making it a critical component in advanced coating and adhesive formulations. It is primarily sought by manufacturers in the paints & coatings, printing inks, and industrial adhesive sectors seeking to enhance product durability and performance.

Application

• Industrial Paints & Protective Coatings: Acts as a key resin binder to improve gloss, hardness, and weather resistance in alkyd and epoxy-based coatings.
• Printing Inks (Gravure & Flexographic): Provides excellent pigment wetting, printability, and fast setting times for high-quality packaging and publication inks.
• Hot-Melt and Pressure-Sensitive Adhesives: Enhances tack, peel strength, and thermal stability in adhesive tapes and labels.
• Polymer Modification & Tackifiers: Used to modify the properties of elastomers and other polymers, improving adhesion and cohesion.
• Sealants and Caulks: Contributes to flexibility, adhesion, and longevity in construction and automotive sealant formulations.
• Paper Sizing and Surface Treatment: Improves water resistance and surface strength of paper and paperboard.
