Description

Formaldehyde, Polymer With 3-Methylphenol is a synthetic phenolic resin, specifically a cresol-formaldehyde polymer, with the CAS registry number 25086-36-6. This thermosetting polymer is valued for its excellent thermal stability, chemical resistance, and adhesive properties, making it a critical intermediate in advanced material synthesis. It is primarily needed by manufacturers in the coatings, adhesives, electronics, and composite materials industries seeking high-performance binders and modifiers.

Application

• High-Temperature Resins & Molding Compounds: As a binder for friction materials (brake pads, clutch facings) and abrasive products requiring thermal stability.
• Industrial Adhesives & Laminates: Used in the formulation of phenolic adhesives for wood products, plywood, and laminated beams.
• Protective Coatings & Linings: A key component in corrosion-resistant coatings for chemical processing equipment, pipes, and tank linings.
• Electronics Encapsulation: Employed in potting compounds and encapsulants for electronic components due to its good electrical insulation properties.
• Foundry Binders: Acts as a core binder in shell molding and no-bake foundry processes for metal casting.
• Composite Materials: Serves as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems.
• Rubber Reinforcement: Used as a tackifying and reinforcing resin in certain specialty rubber compounds.
• Ion-Exchange Resin Precursor: Functions as a starting material in the synthesis of certain ion-exchange resins.
