Description

Castor Oil, Polymer With Dipropylene Glycol, Glycerol, Maleic Anhydride And Phthalic Anhydride CAS NO 71011-17-1 is a specialized polymeric resin derived from castor oil, a renewable resource, modified with key monomers. This product matters as it provides a versatile, bio-based platform for formulating high-performance coatings, adhesives, and inks with excellent adhesion, flexibility, and chemical resistance. It is primarily needed by manufacturers in the paints and coatings, printing inks, and adhesive industries seeking sustainable raw material solutions.

Application

• Alkyd Resins for Industrial & Decorative Paints: Serves as a key bio-based polyol component in the synthesis of alkyd resins, contributing to film formation, durability, and gloss in protective coatings.
• High-Performance Printing Inks: Used as a resin binder in flexographic and gravure inks, offering excellent pigment wetting, printability, and substrate adhesion.
• Adhesives and Sealants: Functions as a tackifying and flexibilizing agent in adhesive formulations, enhancing bond strength and elasticity.
• Polyurethane Dispersions (PUDs): Acts as a renewable polyol for water-based polyurethane systems used in coatings for textiles, leather, and plastics.
• Corrosion-Resistant Primers: Incorporated into primer formulations to improve adhesion to metal substrates and provide a barrier against corrosion.
• Wood Finishes and Varnishes: Imparts good penetration, drying properties, and water resistance to finishes for furniture and flooring.
