Description

Castor Oil/ Phthalic Anhydride/ Trimethylolpropane CAS NO 103819-15-4 is a specialized chemical intermediate, representing a pre-reacted or formulated system based on key raw materials for polymer synthesis. This product is engineered to offer consistent performance and simplified processing for manufacturers, reducing handling complexity and ensuring batch-to-batch uniformity. It is primarily needed by industrial producers in the coatings, adhesives, sealants, and elastomers (CASE) sectors, as well as by resin and plasticizer manufacturers seeking efficient polyol or polyester components.

Application

As a key polyol component in the formulation of alkyd resins for industrial and decorative coatings.
In the production of urethane polymers for flexible foams, adhesives, and elastomers.
As a reactive intermediate for saturated polyester resins used in plasticizers and coil coatings.
For manufacturing plasticizers with enhanced compatibility and performance characteristics.
In the synthesis of specialty lubricants and functional fluids.
As a building block for radiation-curable oligomers in UV-curing inks and coatings.

Quality Control

Our Castor Oil/ Phthalic Anhydride/ Trimethylolpropane undergoes rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. Production is monitored against key parameters including acid value, hydroxyl value, viscosity, and color to guarantee batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and strong oxidizing agents. The container should be kept tightly sealed when not in use to minimize moisture absorption and contamination.
