Description

2-Propenoic acid, 2-methyl-, 2-(diethylamino)ethyl ester, polymer with dodecyl 2-methyl-2-propenoate, ethenylbenzene, hexadecyl 2-methyl-2-propenoate and tetradecyl 2-methyl-2-propenoate CAS NO 64399-38-8 is a high-performance, multi-component acrylic copolymer designed to deliver specific rheological and film-forming properties. This specialized polymer is engineered to provide excellent thickening, stabilization, and adhesion in complex formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance and durability.

Application

• Industrial and Architectural Coatings: Acts as a key binder and rheology modifier in water-based paints, providing improved film integrity, scrub resistance, and pigment stabilization.
• Pressure-Sensitive Adhesives (PSAs): Used in the formulation of tapes and labels to balance tack, peel adhesion, and cohesive strength.
• Textile and Leather Finishes: Imparts durable hand feel, water repellency, and fiber binding properties to treated fabrics and leather goods.
• Paper Coatings and Sizing: Enhances surface strength, printability, and water resistance of paper and cardboard products.
• Specialty Additives: Serves as a dispersing agent or stabilizer in pigment concentrates, ceramic binders, and other advanced material systems.
• Construction Chemicals: Incorporated into cement modifiers and tile adhesives to improve workability, adhesion, and flexibility.
