Description

Castor Oil Dehydrated is a chemically modified derivative of castor oil, produced by removing water molecules to introduce conjugated double bonds, which significantly alters its reactivity and drying properties. This modification makes it a highly valuable intermediate for producing high-performance resins, coatings, and polymers. It is essential for manufacturers in the paint, varnish, adhesive, and specialty chemical industries seeking to enhance product durability and drying speed.

Application

• Alkyd Resins: A key raw material for producing fast-drying, high-gloss alkyd resins used in industrial and decorative paints and coatings.
• Polyurethane Coatings: Used as a polyol component in the formulation of polyurethane coatings, contributing to flexibility and chemical resistance.
• Adhesives & Sealants: Imparts excellent adhesion and water resistance in the production of specialty adhesives and sealants.
• Printing Inks: Serves as a vehicle in quick-setting printing inks, improving gloss and rub resistance.
• Linoleum & Flooring: Acts as a plasticizer and binder in the manufacture of linoleum and other resilient floor coverings.
• Electrical Insulation: Used in varnishes and compounds for insulating wires and electrical components.
• Rust Preventive Coatings: Formulated into corrosion-inhibiting primers and coatings for metal protection.
• Chemical Intermediate: Further processed to manufacture other specialty chemicals, such as surfactants and lubricant additives.

Quality Control

Our Castor Oil Dehydrated is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency and meets specifications for key parameters such as acid value, hydroxyl value, iodine value, and color. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and 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/59-77°F). As this product is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term storage to maintain optimal quality. Keep away from heat, sparks, and open flame.
