Description

Poly(n-Amyl Methacrylate) is a high molecular weight polymer derived from the esterification of methacrylic acid. This compound is valued for its excellent film-forming properties, chemical resistance, and ability to modify the rheological characteristics of various formulations. It serves as a crucial performance additive in industries such as coatings, adhesives, and specialty plastics, where it enhances durability, gloss, and processing behavior. The material is supplied under the identifier CAS NO 28551-45-3.

Application

• Coatings and Paints: Acts as a film-forming agent and rheology modifier in high-performance industrial and automotive coatings to improve flow, leveling, and final gloss.
• Adhesives and Sealants: Used as a tackifier and strength enhancer in pressure-sensitive and structural adhesive formulations.
• Plastic Additives: Functions as a processing aid and impact modifier in engineering plastics and PVC blends to improve melt flow and mechanical properties.
• Printing Inks: Incorporated to adjust viscosity, enhance pigment dispersion, and improve the adhesion and rub resistance of inks.
• Oil & Gas Industry: Employed as a viscosity index improver and pour point depressant in lubricants and drilling fluid formulations.
• Personal Care: Used in nail polishes and hair styling products as a film-forming polymer to provide hold and water resistance.
