Description

Formaldehyde, Polymer With Dimethylbenzene And (1,1-Dimethylethyl)Phenol CAS NO 57979-14-3 is a specialized phenolic resin, a co-polymer of formaldehyde, xylene (dimethylbenzene), and tert-butylphenol. This engineered polymer is valued for its enhanced thermal stability, chemical resistance, and tailored rheological properties compared to standard phenolic resins. It serves as a critical performance additive and binder in advanced industrial applications where durability under harsh conditions is paramount. Key industries that rely on this material include high-performance coatings, specialty adhesives, and composite materials manufacturing.

Application

• High-Temperature Resistant Coatings: Used as a binder in industrial and automotive coatings that must withstand elevated temperatures and chemical exposure.
• Specialty Adhesives and Sealants: Acts as a key resin component in formulations requiring superior bonding strength, water resistance, and durability.
• Friction Materials: Employed as a binder in brake linings and clutch facings due to its thermal stability and binding properties.
• Composite Materials: Serves as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other engineered composites.
• Foundry Resins: Used in shell molding and core-making processes in metal casting for its good flow and cure characteristics.
• Electrical Laminates: Incorporated as a resin in the production of printed circuit board (PCB) substrates and other electrical insulating materials.

Quality Control

Our production of Formaldehyde, Polymer With Dimethylbenzene And (1,1-Dimethylethyl)Phenol adheres to stringent quality management protocols. Each batch is tested against key parameters including viscosity, solids content, gel time, and thermal properties to ensure consistency and performance for your application. Certificates of Analysis (COA) documenting these results are provided and available upon request, ensuring full traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. As with many resinous materials, prolonged exposure to elevated temperatures or direct light may affect product stability.
