Description

Castor Oil, Dehydrated, Polymer With Phthalic Anhydride, Soybean Oil, Trimethylolpropane And Vinyltoluene CAS NO 68927-41-3 is a specialized alkyd resin polymer derived from renewable vegetable oils. This compound is engineered to provide a unique balance of flexibility, adhesion, and chemical resistance in formulated coatings. It is primarily sought after by manufacturers in the paints, coatings, and industrial ink sectors seeking high-performance, bio-based resin components.

Application

• Industrial and Protective Coatings: As a key resin binder in air-drying and baking enamels for metal substrates, machinery, and agricultural equipment.
• Printing Inks: Used in the formulation of specialty inks, including overprint varnishes and packaging inks, for improved gloss and rub resistance.
• Adhesives and Sealants: Imparts flexibility and adhesion in certain adhesive formulations and mastic products.
• Primers: Serves as a component in corrosion-inhibiting primers due to its good wetting properties and adhesion to metals.
• Wood Finishes: Incorporated into varnishes and stains to enhance durability and water resistance.
• Modifying Resin: Used to modify the properties of other synthetic resins, improving flexibility and impact resistance.

Quality Control

Our production of this alkyd resin adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, color, and solids content. Certificates of Analysis (COA) detailing these specifications are available for every shipment to ensure compliance with your formulation requirements.

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. Ideal 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 oxidation.
