Bisphenol A
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. The CAS Number is 80-05-7. It is a colorless solid which is soluble in most common organic solvents, but has very poor solubility in water. BPA is produced on an industrial scale by the condensation reaction of phenol and acetone.
The most common epoxy resins are based on reacting epichlorohydrin with Bisphenol A. This reaction transforms the basic building blocks into a different chemical substance called Bisphenol A diglycidyl ether, which is a low-molecular resin more commonly known as BADGE or DGEBA.
A synthesis of bisphenol A and epichlorohydrin creates a liquid epoxy resin. The epoxy resin is used in solvent-free coatings, adhesives, casting, electrical insulation materials and similar applications with good stability, chemical resistance and high mechanical strength.
