Product Description
4,5-Epoxytetrahydrophthalic acid diglycidyl ester, also known as diglycidyl 4,5-epoxycyclohexane-1,2-dicarboxylate or S-186, is a multifunctional epoxy compound. Its molecular formula is C₁₄H₁₈O₇, and its molecular weight is approximately 298.29 g/mol. Depending on the commercial grade, it may be supplied as a colorless to light-yellow liquid or another specified physical form.
This compound is primarily associated with epoxy resin and specialty polymer applications. Its epoxy functional groups can react with suitable curing agents to form crosslinked polymer networks. When properly formulated, it may contribute to the mechanical strength, thermal performance, adhesion, and chemical resistance of cured materials. Potential application areas include high-performance adhesives, protective coatings, electrical insulation materials, and fiber-reinforced composites. Actual performance depends on epoxy content, purity, curing agent selection, formulation ratio, and processing conditions. Product specifications and compatibility should be verified with the supplier before industrial use.
Product Manufacturing Process
The compound is generally manufactured through controlled chemical synthesis involving an epoxy-functional cyclohexane dicarboxylic acid structure and glycidyl ester functionality. The production process is designed to achieve the required epoxy functionality and product specifications.
Following synthesis, the material may undergo purification, filtration, and other finishing steps. Quality-control testing may include appearance, purity, epoxy value, epoxy equivalent weight, viscosity, and volatile content. Exact manufacturing routes and product specifications vary by manufacturer and grade.
Safety and Storage
Store in a tightly closed container in a cool, dry, and well-ventilated area.
Avoid direct contact with skin and eyes.
Epoxy compounds may cause skin sensitization; wear suitable chemical-resistant gloves, eye protection, and protective clothing.
