Description

Tall Oil/Phthalic/Pentaerythritol/Trimethylolpropane Resin CAS NO 68092-33-1 is a specialized alkyd-type resin synthesized from tall oil fatty acids, phthalic anhydride, and polyols (pentaerythritol and trimethylolpropane). This formulation is engineered to deliver a balanced profile of excellent adhesion, flexibility, and chemical resistance, making it a critical component in high-performance coatings. It is primarily sought after by manufacturers in the industrial coatings, adhesives, and printing ink sectors who require durable, fast-drying, and versatile binder systems.

Application

• Industrial and Protective Coatings: Used as a primary binder in air-drying and force-dried coatings for machinery, agricultural equipment, and structural steel, offering good durability and weather resistance.
• Printing Inks: Serves as a key resin in formulations for overprint varnishes and specialty inks, providing gloss, rub resistance, and good pigment wetting.
• Adhesives and Sealants: Imparts tack, flexibility, and adhesion to substrates in certain adhesive and sealant formulations.
• Modifier for Other Resins: Used to modify the properties of other polymeric systems, enhancing flexibility or drying characteristics.
• Wood Finishes: Employed in varnishes and stains for furniture and flooring, contributing to film formation and substrate protection.

Quality Control

Our Tall Oil/Phthalic/Pentaerythritol/Trimethylolpropane Resin is manufactured under a stringent quality management system. Each batch is tested against key parameters such as acid value, viscosity, color, and solids content to ensure batch-to-batch consistency and performance reliability. 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 away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent skinning and moisture absorption.
