Description

Tall Oil/Phthalic Anhydride/Glycerol/Benzoic Acid Resin CAS NO 68015-50-9 is a synthetic resin produced by the condensation polymerization of tall oil fatty acids, phthalic anhydride, glycerol, and benzoic acid. This versatile alkyd-type resin is engineered to provide excellent adhesion, flexibility, and chemical resistance in formulated coatings and adhesives. It is a critical raw material for industrial manufacturers seeking durable and high-performance binder systems.

Application

• Industrial Coatings: Used as a primary binder or modifying resin in air-drying and baking enamels for machinery, agricultural equipment, and metal substrates.
• Protective & Marine Coatings: Imparts good water resistance and durability in primers and topcoats for structural steel and marine applications.
• Adhesive Formulations: Serves as a tackifying and reinforcing agent in solvent-based and hot-melt adhesives.
• Printing Inks: Employed in resin vehicles for specialty printing inks, contributing to gloss and pigment wetting.
• Can & Coil Coatings: Acts as a component in coatings for food containers and pre-coated metal coils, offering formability and resistance.
• Wood Finishes: Used in varnishes and stains to enhance grain filling, drying time, and film hardness.

Quality Control

Our Tall Oil/Phthalic Anhydride/Glycerol/Benzoic Acid Resin is manufactured under a strict quality management system. Each batch is tested against key parameters including acid value, viscosity, color, and solids content to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product has a typical shelf life of 24 months from the date of manufacture.
