Description

Fatty acids, C16-18 and C18-unsatd., polymers with benzoic acid, 2-(dimethylamino)ethyl methacrylate, isophthalic acid, Me methacrylate, 2-mercaptoethanol, pentarythritol, styrene is a specialized polymeric resin designed for high-performance industrial applications. This multi-component copolymer offers a unique balance of properties derived from its fatty acid backbone and functional monomers, making it a valuable additive and modifier. It is primarily utilized in the formulation of advanced coatings, adhesives, and inks where enhanced flow, adhesion, and durability are required. The product is supplied under CAS No. 129893-04-5.

Application

• Industrial Coatings: As a rheology modifier and adhesion promoter in solvent-based and high-solids coatings for metal, plastic, and wood substrates.
• Printing Inks: To improve pigment wetting, gloss, and printability in flexographic and gravure inks.
• Adhesives & Sealants: As a tackifier and flexibilizing agent in structural and pressure-sensitive adhesive formulations.
• Polymer Modification: As an additive to enhance the impact resistance, flexibility, and compatibility of various thermoplastic and thermoset resins.
• Overprint Varnishes: To provide scratch resistance and a high-gloss finish in protective coatings for packaging.
• Marine & Protective Coatings: Contributing to corrosion resistance and long-term durability in harsh environmental conditions.
