Description

Coconut Oil, Polymer With Phthalic Anhydride And Trimethylolpropane CAS NO 68647-88-1 is a specialized alkyd resin intermediate derived from natural coconut oil, phthalic anhydride, and trimethylolpropane. This unique polymer offers a sustainable and versatile building block for formulating high-performance coatings and resins with excellent flexibility and adhesion. It is primarily needed by manufacturers in the paints & coatings, adhesives, and polymer modification industries seeking bio-based components.

Application

• As a reactive modifier and plasticizer in alkyd resin formulations for industrial and decorative paints.
• Key intermediate for manufacturing flexible, air-drying coatings with good weathering resistance.
• Bio-based component in adhesive and sealant systems to enhance tack and elasticity.
• Raw material for producing specialty polymers requiring a combination of hardness and impact resistance.
• Modifier for printing ink vehicles to improve gloss and flow properties.
• Used in the formulation of corrosion-resistant primers and metal coatings.
