Description

Soybean Oil/ Rosin/ Maleic Anhydride/ Glycerol Resin CAS NO 68132-16-1 is a versatile modified alkyd resin synthesized from renewable and petrochemical feedstocks. This product matters for formulators seeking a cost-effective, bio-based component that enhances film formation, adhesion, and flexibility in coatings and adhesives. It is needed by manufacturers in the paints & coatings, printing inks, adhesive, and sealant industries.

Application

• Architectural and Industrial Coatings: As a film-forming resin in solvent-borne and high-solid alkyd paints, providing good gloss and durability.
• Printing Inks: Used in lithographic and letterpress inks to improve pigment wetting, gloss, and printability.
• Adhesives and Sealants: Acts as a tackifier and modifying resin to enhance bond strength and flexibility.
• Wood Finishes: Imparts good penetration and drying characteristics in varnishes and stains.
• Metal Primers: Contributes to corrosion resistance and substrate adhesion.
• Caulks and Putties: Provides body and flexibility in non-hardening sealant formulations.

Quality Control

Our production of Soybean Oil/ Rosin/ Maleic Anhydride/ Glycerol Resin follows stringent batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, color, and solids content to ensure performance in target applications. Certificates of Analysis (COA) documenting these specifications are available upon request for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat sources and open flames. Due to its oxidizable nature, minimize headspace in opened containers. For long-term storage, consider blanketing with an inert gas such as nitrogen.
