Prospects of photocuring and 4-Benzoylphenyl Methacrylate

Photocuring refers to the curing process of monomer, oligomer or polymeric matrix under light induction, which is generally used in film forming. The technology has the characteristics of high efficiency, wide adaptability, economy, energy saving and environmental protection.

Free-radical UV curing advantages

Fast curing

East-to-adjust performance

Cationic UV curing advantages

High hardness

Small volumetric shrinkage

High bond strength

Abrasion resistant

Cationic curing system has the disadvantages of slow curing speed, few types of oligomers and reactive diluents, high price of photoinitiators, and difficult adjustment of cured product performance. If the free radical and cationic hybrid UV curing system are properly combined, it is expected to learn from each other's strengths, and obtain a UV-curable adhesive with fast curing speed, small volume shrinkage, low internal stress of the adhesive layer and high bonding strength.

Dual curing technology combines UV curing with other curing methods. UV curing has its own shortcomings: it can be cured only where UV light can be irradiated, and it is difficult to cure completely where UV light is not irradiated. The dual curing method combines the advantages of various polymerization reactions and shows a good synergistic effect. The application of dual curing technology to the development of adhesives will definitely give UV curing adhesives more powerful competitiveness. With the help of dark reaction, dual-curing adhesives can overcome many limitations of UV-curing adhesives. They make the UV curing system applicable to opaque materials and complex-shaped substrates, as well as ultra-thick coatings and colored coatings.
