Description

Phenol, 4,4-(1-Methylethylidene)Bis-, Polymer With (Chloromethyl)Oxirane, Reaction Products With 1,2-Cyclohexanediamine CAS NO 87041-44-9 is a specialized, high-performance epoxy resin hardener derived from bisphenol A, epichlorohydrin, and 1,2-cyclohexanediamine. This advanced formulation is engineered to provide superior chemical resistance, thermal stability, and excellent mechanical properties in cured epoxy systems. It is a critical component for industrial manufacturers requiring durable, high-performance coatings, adhesives, and composite materials.

Application

• High-Performance Industrial Coatings: Used as a curing agent for epoxy-based protective coatings in marine, oil & gas, and chemical processing environments due to its excellent resistance to strong alkalis and organic solvents.
• Structural Adhesives & Laminates: Serves as a key hardener in adhesives for aerospace, automotive, and construction applications, offering strong bonds and durability.
• Composite Materials: Essential for formulating epoxy matrices in fiber-reinforced plastics (FRP) used in wind turbine blades, automotive parts, and sporting goods.
• Electrical Encapsulation & Potting: Provides reliable insulation and protection for electronic components, transformers, and sensors.
• Flooring & Civil Engineering: Used in high-traffic industrial flooring, repair mortars, and grouts where chemical and abrasion resistance are paramount.
• Tooling & Molding: Employed in the production of molds, fixtures, and patterns that require dimensional stability and thermal resistance.

Quality Control

Our production of this advanced epoxy hardener adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Key parameters such as amine value, viscosity, color, and epoxy equivalent weight are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Due to its reactivity, keep containers tightly sealed when not in use to prevent moisture absorption and contamination.
