Description

Oxirane, Methyl-, Polymer With Oxirane, Ether With (Chloromethyl)Oxirane Polymer With 4,4'-(1-Methylethylidene)Bis[Phenol] is a specialized epoxy-functional polymer, commonly known as an epoxy resin or a polyglycidyl ether of bisphenol A. This high-performance material is valued for its excellent chemical resistance, strong adhesion, and outstanding mechanical properties upon curing. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, composites, and electronics industries, where durable, cross-linked polymer networks are required.

Application

• Protective & Industrial Coatings: Formulation of high-performance epoxy paints, primers, and floor coatings for marine, automotive, and industrial applications requiring corrosion and chemical resistance.
• Structural Adhesives & Sealants: Used as a base resin in high-strength, durable adhesives for aerospace, automotive, and construction bonding.
• Composite Materials: Acts as the matrix resin in fiber-reinforced plastics (FRP) for wind turbine blades, automotive parts, and sporting goods.
• Electrical & Electronic Encapsulation: Potting and encapsulation of electronic components, transformers, and insulators due to excellent electrical insulation properties.
• Civil Engineering & Construction: Key component in grouts, mortars, and repair compounds for concrete rehabilitation and flooring systems.
• Tooling & Molding: Used in the production of molds, patterns, and master models for casting and prototyping.

Quality Control

Our epoxy resins are manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and performance. Key parameters monitored include epoxide equivalent weight (EEW), viscosity, color, and hydrolyzable chloride content. Certificates of Analysis (COA) detailing these specifications are available for every shipment. We can supply products meeting various industry standards based on customer 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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and incompatible materials.
