Description

Fatty Acids, Tall-Oil, Polymers With Benzoic Acid, Maleic Anhydride, Pentaerythritol, Phthalic Anhydride And Trimethylolethane (CAS No. 68139-38-8) is a complex, high-performance polymeric resin derived from renewable tall oil fatty acids and key synthetic monomers. This specialized alkyd-type polymer is engineered to deliver exceptional film-forming properties, chemical resistance, and durability in demanding industrial applications. It is a critical raw material for formulators in the coatings, adhesives, and ink industries seeking to enhance product performance with a versatile polymeric backbone.

Application

• Industrial and Protective Coatings: As a primary resin or modifier in high-performance alkyd paints, marine coatings, and corrosion-resistant primers.
• Printing Inks: Used in the formulation of overprint varnishes and specialty inks requiring excellent gloss, adhesion, and rub resistance.
• Adhesives and Sealants: Acts as a tackifying agent and polymeric backbone to improve adhesion, flexibility, and cohesive strength.
• Resin Modification: Employed to modify the properties of other polymers, enhancing flexibility, drying time, or chemical resistance.
• Wood Finishes: A key component in varnishes and wood stains, providing durable, protective films with good penetration.

Quality Control

Our production of this polymeric resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to support your quality assurance processes.

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 product is easily oxidized; prolonged storage should be under an inert atmosphere (e.g., nitrogen blanket) for optimal stability. Keep away from heat sources and open flames.
