Description

Soybean Oil, Glycerin, Phthalic Anhydride, Maleic Anhydride Resin is a specialized alkyd resin intermediate synthesized from key raw materials including soybean oil, glycerin, phthalic anhydride, and maleic anhydride. This product is engineered to offer a versatile and reactive backbone for the formulation of high-performance surface coatings and inks. It is primarily sought after by manufacturers in the paints, coatings, printing inks, and adhesive industries who require a resin with excellent film-forming properties, adhesion, and durability.

Application

• Primary raw material for alkyd resin production used in industrial and decorative paints.
• Binder component in high-gloss and fast-drying printing inks for packaging and publications.
• Modifying resin for air-drying and baking enamels to enhance hardness and chemical resistance.
• Key ingredient in corrosion-resistant primer formulations for metal substrates.
• Base for wood coating resins, providing good penetration and finish.
• Intermediate in the synthesis of specialty polymers for adhesives and sealants.

Quality Control

Our alkyd resin intermediates are produced under strict process controls to ensure batch-to-batch consistency and performance. Quality is verified through a series of analytical tests including acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting all key parameters 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 at room temperature (15-25°C). This material is easily oxidized (store under inert atmosphere) and should be kept away from heat sources and open flames. Keep container tightly sealed when not in use to prevent skinning and moisture absorption.
