Description

Formaldehyde, Polymer With 1,3-Benzenediol And Phenol, Sodium Salt is a synthetic phenolic resin derivative, specifically a sodium salt of a formaldehyde copolymer with resorcinol (1,3-benzenediol) and phenol. This compound is valued for its role as a reactive intermediate and cross-linking agent, offering enhanced water solubility and ionic character compared to its non-salt counterparts. It is primarily utilized by manufacturers in the adhesives, coatings, and specialty polymer industries seeking to modify resin properties for specific performance requirements.

Application

• Adhesive Formulations: Acts as a cross-linking agent or modifier in wood adhesives, particularly for moisture-resistant bonds.
• Foundry Resins: Used in binder systems for sand casting in metal foundries.
• Friction Materials: Serves as a resin component in brake linings and clutch facings.
• Abrasive Products: Employed as a binder in grinding wheels and coated abrasives.
• Industrial Coatings: Functions as a modifying resin to impart specific chemical resistance or curing properties.
• Rubber Reinforcement: Can be used as a tackifier or reinforcing resin in certain rubber compounds.
• Textile Treatment: Applied in finishes to improve fabric durability or water repellency.
• Ion-Exchange Materials: Potential use as a precursor or component in specialty ion-exchange resins.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We implement strict process controls for consistency in composition, solubility, and reactivity. Certificates of Analysis (COA) are available upon request, detailing key parameters such as solids content, viscosity, pH, and ionic character to meet your specific application 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). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product performance.
