Description

Oxirane, (Chloromethyl)-, Polymer With α-Hydro-ω-Hydroxypoly[ Oxy(Methyl-1,2-Ethanediyl)], 2-Propenoate CAS NO 68130-31-4 is a specialized reactive polymer, also known as an epoxy acrylate or glycidyl methacrylate (GMA) functionalized polyether. This compound is engineered to deliver a unique combination of flexibility, adhesion, and crosslinking reactivity, making it a critical performance additive. It is primarily sought after by formulators in the coatings, adhesives, and advanced composites industries who require enhanced mechanical properties and chemical resistance in their final products.

Application

• UV-Curable Coatings & Inks: Acts as a key oligomer to improve film flexibility, adhesion to difficult substrates, and cure speed.
• Structural Adhesives & Sealants: Enhances toughness, peel strength, and environmental durability in epoxy and acrylic-based adhesive systems.
• Fiber-Reinforced Composites: Used as a matrix resin modifier to increase interlaminar shear strength and impact resistance.
• Electronic Encapsulants & Potting Compounds: Provides excellent electrical insulation properties along with low shrinkage and thermal stress relief.
• Industrial & Protective Coatings: Imparts superior corrosion resistance, chemical stability, and weatherability to metal and concrete coatings.
• 3D Printing Resins: Serves as a functional prepolymer in stereolithography (SLA) and digital light processing (DLP) resins for high-performance prototypes and parts.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Every batch is characterized for critical parameters including epoxy equivalent weight (EEW), acrylate functionality, viscosity, and color to ensure batch-to-batch consistency and performance reliability. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment.

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 and incompatible materials such as strong acids, bases, and peroxides. Under these conditions, the product is typically stable for 12 months from the date of receipt.
