Description

Fatty acids, tall-oil, polymers with ethylene glycol, glycerol, isophthalic acid, pentaerythritol and propylene glycol Tall oil fatty acid, pentaerythritol, glycerin, ethylene glycol, propylene glycol, isophthalic acid resin is a specialized alkyd resin derived from renewable tall oil fatty acids and polyols, designed to offer a versatile and sustainable polymeric backbone. This product matters for its excellent film-forming properties, adhesion, and flexibility, making it a high-performance component in demanding industrial formulations. It is primarily needed by manufacturers in the coatings, adhesives, and ink industries seeking bio-based alternatives with robust chemical and physical characteristics.

Application

• Industrial Coatings Binder: Used as a primary resin in air-drying and baking enamels for machinery, agricultural equipment, and metal substrates, providing durability and corrosion resistance.
• Adhesive Formulations: Serves as a tackifying and flexibilizing agent in structural and pressure-sensitive adhesives (PSAs).
• Printing Inks: Acts as a resinous vehicle in solvent-based and overprint varnishes, enhancing gloss, rub resistance, and pigment wetting.
• Caulks and Sealants: Imparts flexibility and adhesion in elastomeric sealants for construction and automotive applications.
• Primer Coatings: Functions as a key ingredient in metal primers, offering excellent substrate wetting and intercoat adhesion.
• Wood Finishes: Utilized in varnishes and stains for furniture and flooring, contributing to a hard, protective film.

Quality Control

Our alkyd resins undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as acid value, viscosity, solids content, and color are strictly monitored. Certificates of Analysis (COA) detailing these specifications are available upon request, supporting your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from strong alkalis and incompatible organic solvents. Under these conditions, the product has a typical shelf life of 12 months from the date of manufacture.
