Description

Fatty acids, tall-oil, polymers with ethylene glycol, glycerol, pentaerythritol, phthalic anhydride and tall oil is a complex polymeric resin derived from renewable tall oil fatty acids, polyols, and phthalic anhydride. This versatile alkyd-type polymer is engineered to deliver excellent film-forming properties, adhesion, and flexibility, making it a crucial intermediate for high-performance coatings and adhesives. It is primarily needed by formulators in the paints & coatings, printing inks, and industrial adhesive sectors seeking sustainable, high-quality resin solutions. The product is identified by CAS No. 68513-41-7.

Application

• Industrial and Protective Coatings: As a primary resin binder in air-drying and baking enamels for machinery, agricultural equipment, and metal substrates.
• Printing Inks: Used in the formulation of offset, gravure, and flexographic inks to provide gloss, rub resistance, and pigment wetting.
• Adhesives and Sealants: Acts as a tackifying and film-forming agent in pressure-sensitive and assembly adhesives.
• Wood Finishes: Imparts durability, water resistance, and clarity in varnishes and stains for furniture and flooring.
• Corrosion Inhibitive Primers: Serves as a resin component in primers designed for rust prevention on steel and other ferrous metals.
• Architectural Paints: Modifier for alkyd paints to enhance brushing properties, dry time, and final film integrity.

Quality Control

Our tall oil alkyd polymers are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested against internal specifications. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, consider blanketing with an inert gas (e.g., nitrogen) to preserve quality. Keep away from heat sources and open flames.
