Description

Formaldehyde, Polymer With 4-(1,1-Dimethylethyl)Phenol, 4-(1,1-Dimethylpropyl)Phenol, 4-Nonylphenol And Oxirane is a specialized phenolic-modified epoxy novolac resin, a high-performance polymer synthesized from formaldehyde, alkylphenols, and epichlorohydrin (oxirane). This compound matters for its exceptional thermal stability, chemical resistance, and adhesive properties, making it a critical component in demanding industrial formulations. It is primarily needed by manufacturers in the coatings, adhesives, and advanced composite materials sectors seeking to enhance product durability and performance under harsh conditions. CAS No. 67905-90-2.

Application

• High-Temperature Resistant Coatings: As a binder in industrial and protective coatings for pipelines, chemical plants, and automotive underbody applications.
• Advanced Composite Materials: As a matrix resin or toughening agent in fiber-reinforced plastics (FRP) for aerospace and automotive components.
• Electronics Encapsulation: Used in potting compounds and encapsulants for semiconductors and electronic assemblies requiring thermal and chemical stability.
• Structural Adhesives: A key ingredient in high-strength, durable adhesives for metal-to-metal and composite bonding.
• Molding Compounds: For the production of heat-resistant and dimensionally stable thermoset parts via compression or transfer molding.
• Friction Materials: As a phenolic resin modifier in brake pads and clutch facings to improve performance and reduce wear.

Quality Control

Our production of Formaldehyde, Polymer With 4-(1,1-Dimethylethyl)Phenol, 4-(1,1-Dimethylpropyl)Phenol, 4-Nonylphenol And Oxirane adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including assessment of epoxy equivalent weight (EEW), viscosity, softening point, and residual monomer content. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen blanket) to preserve stability and prevent gelation. Keep away from heat sources, open flames, and incompatible materials such as strong acids and bases.
