Description

Hydroxyethyl Methacrylate-Ethyl Methacrylate is a high-purity, reactive monomer mixture designed for advanced polymer synthesis. This product is valued for its ability to impart a balance of hydrophilicity, flexibility, and durability to final polymer matrices, enhancing performance in demanding applications. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to fine-tune material properties.

Application

• UV-Curable Coatings & Inks: A key component in formulations requiring fast curing, high gloss, and excellent adhesion to various substrates.
• Acrylic Resin Modification: Used to copolymerize with other acrylates to improve flexibility, impact resistance, and weatherability of acrylic resins.
• Pressure-Sensitive Adhesives (PSAs): Enhances tack, peel strength, and cohesion in adhesive tapes and labels.
• Dental & Biomedical Polymers: Employed in the synthesis of biocompatible materials for dental composites, bone cements, and contact lenses.
• Fiber Optic Coatings: Provides protective, flexible cladding with stable optical properties for communication fibers.
• Industrial Sealants: Contributes to the elasticity and chemical resistance of sealants used in construction and automotive applications.

Quality Control

Our Hydroxyethyl Methacrylate-Ethyl Methacrylate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for composition and purity, to ensure consistency and performance. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources, sparks, and open flame. Due to the presence of polymerizable monomers, storage with an appropriate inhibitor is standard, and containers should be kept tightly sealed when not in use to prevent moisture absorption and premature polymerization.
