Description

Tall Oil/ Phthalic Anhydride/ Pentaerythritol/ Pg Resin CAS NO 68459-26-7 is a specialized alkyd resin intermediate synthesized from tall oil fatty acids, phthalic anhydride, and pentaerythritol. This compound is engineered to provide a versatile backbone for high-performance surface coatings, offering an excellent balance of hardness, flexibility, and chemical resistance. It is a critical raw material for formulators in the paints, varnishes, and industrial coatings industries seeking to enhance product durability and application properties.

Application

• Primary binder for industrial and architectural alkyd paints and enamels.
• Key component in the formulation of high-solids and solvent-borne coatings for metal substrates.
• Resin intermediate for corrosion-resistant primers and maintenance coatings.
• Used in manufacturing air-drying and baking finishes for automotive and machinery.
• Base for wood varnishes and furniture coatings, providing good gloss and drying characteristics.
• Modifier resin in printing inks to improve adhesion and film formation.

Quality Control

Our alkyd resin intermediates are manufactured under strict process controls to ensure batch-to-batch consistency for your formulations. Quality is verified through parameters including acid value, viscosity, color, and solids content. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your technical 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 material is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided to maintain product integrity. Keep away from heat sources and open flame.
