Description

Tannins, Polymers With Formaldehyde And Phenol is a synthetic phenolic resin derived from the condensation polymerization of tannin extracts with formaldehyde and phenol. This compound is valued for its excellent binding, cross-linking, and adhesive properties, making it a crucial component in industrial manufacturing. It is primarily needed by producers in the wood composite, foundry, and friction materials industries seeking high-performance, thermosetting resin systems.

Application

• Wood Adhesives: As a binder in the production of plywood, particleboard, and oriented strand board (OSB), offering an alternative to pure phenol-formaldehyde resins.
• Foundry Sand Binders: Used as a core and mold binder in metal casting for its good thermal stability and breakdown properties.
• Friction Materials: Serves as a resin binder in brake linings and clutch facings, providing necessary heat resistance and structural integrity.
• Industrial Abrasives: Acts as a bonding agent in grinding wheels and abrasive products.
• Thermoset Molding Compounds: Utilized in composite materials for electrical components and automotive parts.
• Leather Tanning Auxiliaries: Employed as a retanning agent or syntan to modify leather properties.
• Oilfield Chemicals: Potential use as a fluid loss control additive or cross-linker in drilling mud formulations.
