Description

Phenol, 4,4-(1-methylethylidene)bis-, polymer with .alpha.-(2-aminomethylethyl)-.omega.-(2-aminomethoxy)polyoxy(methyl-1,2-ethanediyl) and (chloromethyl)oxirane CAS NO 68318-44-5 is a specialized epoxy-amine adduct polymer, engineered for high-performance applications. This advanced material is valued for its excellent adhesion, chemical resistance, and mechanical properties, making it a critical component in demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and advanced composite sectors for creating durable, protective layers and structural bonds.

Application

• High-Performance Coatings: Used as a curing agent or modifier in epoxy-based industrial, marine, and protective coatings for superior corrosion and chemical resistance.
• Structural Adhesives: Serves as a key component in epoxy adhesives for aerospace, automotive, and construction applications requiring high strength and durability.
• Composite Materials: Acts as a matrix resin or toughening agent in fiber-reinforced plastics (FRP) and other composite systems.
• Electrical Encapsulation: Employed in potting and encapsulation compounds for electronic components due to its good electrical insulation and adhesion properties.
• Flooring and Civil Engineering: Utilized in high-build, self-leveling, and grouting compounds for industrial floors and infrastructure repair.
• Tooling and Molding: Applied in the production of molds, models, and master patterns that require dimensional stability and release properties.

Quality Control

Our Phenol, 4,4-(1-methylethylidene)bis-, polymer with .alpha.-(2-aminomethylethyl)-.omega.-(2-aminomethylethoxy)polyoxy(methyl-1,2-ethanediyl) and (chloromethyl)oxirane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of amine value, epoxy equivalent weight, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and incompatible materials.
