Description

2-Propenoic Acid, 2-Methyl-, Octadecyl Ester, Polymer With Butyl 2-Propenoate And Methyl 2-Propenoate is a high-performance, multi-component acrylic copolymer designed to deliver enhanced film-forming properties and durability. This specialized polymer is engineered to provide excellent water resistance, flexibility, and adhesion across a wide range of substrates. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to improve product performance and longevity. The compound, identified by CAS No. 67827-73-0, meets the stringent requirements for industrial and specialty chemical applications.

Application

• Industrial and Protective Coatings: Used as a key film-forming agent in metal primers, machinery enamels, and corrosion-resistant topcoats.
• Adhesive Formulations: Imparts strong bonding strength and flexibility in pressure-sensitive adhesives (PSAs) and structural adhesives.
• Textile and Leather Finishes: Serves as a durable binder and coating to provide water repellency and abrasion resistance.
• Printing Inks: Enhances gloss, adhesion, and rub resistance in overprint varnishes and specialty ink systems.
• Caulks and Sealants: Improves elasticity, weather resistance, and long-term performance in construction and automotive sealants.
• Paper Coatings: Used to create barrier coatings and improve surface properties like gloss and printability.
