With the advancement of productiontechnology, thermosetting resins are gradually replaced by photocurable resins.
Photocrosslinkable polymers, initiators, andadditives. The most essential difference between them and thermosetting resins
is that the curing process relies on the absorption of the corresponding
wavelength. The chemical reaction caused by the radiation of light causes the
photocurable resin to change from a liquid to a solid. This curing method is
often used in
super thin 115mm cutting disc.
It changes from liquid to solid as aresult of molecular weight increase, rather than solvent evaporation, so it has
the advantages of rapid curing, no pollution, andenergy saving, but the limiting factor is the high price of raw materials. In
terms of thin cutting sheets, China has successfully developed
super-thin 115mm cutting disc with a thickness of 0.15mm using photocurable resin as a bonding agent, and
successfully completed the cutting test of single crystal silicon wafers. With
the development of technology, this method will It is being used more and more
widely.
