Description

2-Propenoic Acid,2-Methyl-,Polymer With Ethyenylbenzene,2-Ethylhexyl 2-Propenoate,2-Hydroxyethyl 2-Methyl-2-Propenoate And Methyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent adhesion, chemical resistance, and film-forming characteristics. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product durability and performance. The compound is supplied under CAS No. 32216-84-5.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, automotive underbody coatings, and corrosion-resistant finishes.
• Adhesives and Sealants: Serves as a primary polymer in pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents.
• Textile and Leather Finishes: Provides durable, flexible coatings and binders for fabric backings and leather finishing.
• Printing Inks: Acts as a resin component in overprint varnishes and specialty inks requiring good gloss and rub resistance.
• Plastic Modifiers: Employed as an impact modifier or processing aid to enhance the properties of rigid plastic compounds.
• Caulks and Putties: Imparts flexibility, adhesion, and water resistance to automotive and industrial caulking compounds.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as solid content, viscosity, acid value, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with each shipment. We support compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity.
