Description

2-Propenoic acid, 2-methyl-, butyl ester, polymer with dodecyl 2-methyl-2-propenoate, eicosyl 2-methyl-2-propenoate, hexadecyl 2-methyl-2-propenoate, octadecyl 2-methyl-2-propenoate, pentadecyl 2-methyl-2-propenoate, tetradecyl 2-methyl-2-propenoate and tridecyl 2-methyl-2-propenoate is a high-performance, multi-component acrylic copolymer designed to deliver exceptional film-forming properties and durability. This specialized polymer is engineered to provide a unique balance of flexibility, water resistance, and adhesion to diverse substrates. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a key film-forming agent in metal primers, automotive underbody coatings, and corrosion-resistant finishes.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and cohesive strength in labels, tapes, and graphic films.
• Textile and Leather Finishes: Provides durable, flexible, and water-repellent coatings for fabrics and synthetic leather.
• Printing Inks: Enhances gloss, rub resistance, and adhesion for various ink systems, including overprint varnishes.
• Caulks and Sealants: Contributes to elasticity, adhesion, and long-term weatherability in construction and automotive sealants.
• Paper Coatings: Improves surface strength, printability, and moisture barrier properties of specialty papers.
