Description

Formaldehyde-1-Naphthalenolcopolymer CAS NO 25359-91-5 is a synthetic phenolic resin polymer formed by the condensation of formaldehyde with 1-naphthalenol (1-naphthol). This specialized copolymer is valued for its thermal stability and chemical resistance, making it a critical component in high-performance industrial applications. It is primarily sought by manufacturers in the coatings, adhesives, and advanced material sectors for its role as a modifying resin or cross-linking agent.

Application

• As a modifying resin in high-temperature and chemical-resistant industrial coatings and paints.
• As a cross-linking agent or hardener in specialty adhesives and sealants requiring enhanced durability.
• As a reinforcing component in composite materials and molded plastics to improve mechanical properties.
• In the formulation of foundry resins for sand casting in metalworking industries.
• As a precursor or intermediate in the synthesis of more complex polymeric materials and ion-exchange resins.
• Potential use in encapsulation materials and electronic potting compounds for its insulating properties.

Quality Control

Our Formaldehyde-1-Naphthalenolcopolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in properties such as molecular weight distribution, softening point, and residual monomer content. Certificates of Analysis (COA) documenting these parameters 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). Keep away from strong oxidizing agents, strong acids, and strong bases. The product may be hygroscopic; ensure containers are sealed after use to minimize moisture absorption.
