Description

Fatty Acids, Tall-Oil, Polymers With Ethylene Glycol, Pentaerythritol, Phthalic Anhydride, Styrene And Vinyltoluene CAS NO 124751-13-9 is a specialized polymeric resin derived from tall oil fatty acids, a renewable resource, and key monomers including styrene and vinyltoluene. This product matters for formulators seeking high-performance, versatile alkyd-type resins that offer excellent adhesion, flexibility, and durability in demanding coatings applications. It is primarily needed by manufacturers in the paints, coatings, inks, and adhesives industries for producing air-drying or baking finishes.

Application

• Industrial and Protective Coatings: As a primary resin binder for metal primers, machinery enamels, and corrosion-resistant finishes.
• Architectural Paints: Formulation of high-quality exterior house paints and trim paints requiring good weathering and gloss retention.
• Printing Inks: Used in overprint varnishes and specialty inks where rapid drying and film hardness are critical.
• Adhesives and Sealants: As a tackifying or modifying resin to enhance adhesion and cohesive strength.
• Wood Finishes: For varnishes and stains that provide a durable, protective film with good penetration.
• Automotive Refinish: In repair primers and topcoats that require excellent sanding properties and intercoat adhesion.

Quality Control

Our alkyd resins undergo rigorous quality testing to ensure batch-to-batch consistency and performance in your formulations. Key parameters such as acid value, viscosity, solids content, and color are strictly monitored. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Under these conditions, the product has a typical shelf life of 12 months from the date of manufacture.
