Description

Diallyl Hexahydrophthalate is a specialized diester monomer derived from hexahydrophthalic anhydride and allyl alcohol. This compound is valued for its role as a reactive diluent and crosslinking agent in the synthesis of high-performance thermosetting polymers. It is primarily sought after by manufacturers in the advanced materials sector for applications requiring enhanced thermal stability, chemical resistance, and low shrinkage. The product is supplied under the identifier CAS NO 13846-31-6.

Application

• As a reactive diluent and crosslinker in the formulation of unsaturated polyester resins (UPR).
• Key monomer for producing high-performance, low-profile additives in Sheet Molding Compounds (SMC) and Bulk Molding Compounds (BMC).
• Used in the synthesis of specialty coatings and adhesives requiring excellent weatherability and chemical resistance.
• Component in the manufacture of fiber-reinforced plastics for automotive and marine applications.
• Intermediate in the production of specialty plasticizers and modifiers for polymer systems.
• Used in electrical laminates and encapsulants due to its good dielectric properties.
