Bisphenol A epoxy acrylate is prepared by the reaction of bisphenol A epoxy resin and acrylic acid. Bisphenol A epoxy resin is produced by the reaction of bisphenol A and epichlorohydrin under alkaline conditions. By controlling the ratio of the two raw materials and the reaction conditions, bisphenol A epoxy resins with different polymerization degrees can be obtained. The higher the polymerization degree, the larger the molecular weight and the smaller the epoxy value.

PCB, the Chinese name is called printed circuit board, is an important electronic component, the support of electronic components, and also the carrier for the electrical connection of electronic components, so it is called the ‘mother of electronic products’. Don't underestimate this seemingly ordinary board, it is a kaleidoscope in the electronics industry, turning our technological dreams into reality.

Epoxy acrylate is made by esterification of epoxy resin and acrylic acid or methacrylic acid. According to the structure, it can be divided into bisphenol A epoxy acrylate, modified epoxy acrylate, phenolic epoxy acrylate, and epoxidized oil acrylate. Among them, bisphenol A epoxy acrylate is the most commonly used and has the largest usage.

UV curing technology is a high-efficiency, energy- saving and environmentally friendly high-tech curing technology developed since the 1960s. It refers to the process in which the photoinitiator in the system absorbs ultraviolet light to generate free radicals under the irradiation of high-energy ultraviolet light as the curing energy, triggering a chain polymerization reaction between UV resin and monomer, causing the liquid phase system to polymerize, cross-link and cure instantly.
