Description

Methacrylic Acid, 2-Hydroxyethyl Ester Polymer With Ethyl Acrylate, Ethyl Methacrylate And Methyl Methacrylate is a specialized acrylic copolymer designed to deliver a unique balance of properties for advanced coating and adhesive formulations. This multi-monomer polymer is engineered to provide enhanced adhesion, flexibility, and durability, making it a critical component for high-performance industrial applications. It is primarily sought after by manufacturers in the coatings, pressure-sensitive adhesives, and specialty resin industries for its ability to improve product performance and longevity.

Application

• Primary binder or co-binder in high-performance industrial and architectural coatings.
• Key component in the formulation of pressure-sensitive adhesives (PSAs) for tapes and labels.
• Used in overprint varnishes and printing inks to enhance gloss, adhesion, and rub resistance.
• Modifier for thermoplastic resins to improve impact resistance and surface characteristics.
• Base polymer for specialty sealants and caulks requiring excellent weatherability and flexibility.
• Raw material for the production of cross-linked polymer networks in advanced composite materials.

Quality Control

Our acrylic copolymer products are manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against critical parameters including monomer content, molecular weight distribution, viscosity, and glass transition temperature (Tg). A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

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, an inert atmosphere (e.g., nitrogen) is recommended to prevent potential oxidation or skin formation.
