Description

Castor Oil, Dehydrated, Polymer With Oleic Acid, Phthalic Anhydride, Soybean Oil, Trimethylolpropane And Vinyltoluene CAS NO 68917-97-5 is a specialized, high-performance alkyd resin intermediate designed for demanding industrial applications. This modified polymer offers a unique balance of flexibility, adhesion, and chemical resistance derived from its multi-component formulation. It is a critical raw material for manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product durability and performance. The compound's tailored structure provides excellent compatibility and reactivity for formulating advanced polymeric systems.

Application

• Industrial Coatings Binder: Serves as a key resin component in high-quality alkyd paints, varnishes, and enamels for metal, wood, and concrete substrates.
• Adhesive & Sealant Formulation: Used as a tackifying and flexibilizing agent in structural adhesives, pressure-sensitive adhesives (PSAs), and elastomeric sealants.
• Printing Ink Resin: Imparts gloss, adhesion, and drying properties in specialty printing inks, including overprint varnishes and packaging inks.
• Corrosion-Resistant Primers: Formulated into primers and undercoats that provide excellent substrate wetting and barrier protection against corrosion.
• Plasticizer & Modifier: Acts as a polymeric plasticizer and compatibility enhancer in PVC and other polymer blends to improve flexibility and processing.
• Marine & Protective Coatings: A vital ingredient in coatings requiring enhanced water resistance, weatherability, and durability for marine and industrial environments.

Quality Control

Our production of this alkyd resin intermediate adheres to strict batch-to-batch consistency protocols to ensure reliable performance in your formulations. Quality is monitored through key parameters including acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting these specifications are available for every shipment. While produced under a quality management system, this industrial-grade product is typically supplied to meet agreed-upon technical specifications rather than pharmacopeial standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This material is light-sensitive and should be stored away from direct light sources. As it can be easily oxidized, it is recommended to store under an inert atmosphere or with a nitrogen blanket for long-term storage, and to keep containers tightly sealed when not in use to minimize contact with air.
