UV glue, also called shadowless glue, is a type of adhesive that needs to be cured by ultraviolet light. The conditions required in the curing process of UV glue are the UV glue curing energy and the UV wavelength required by the photoinitiator.

UV glue curing energy is one of the conditions required in the UV glue curing process. It is a parameter used to represent the intensity of UV light. The unit is mJ/cm2, which can also be expressed by multiplying mW/cm2 by the irradiation time. mJ/cm2 is read as 1 millijoule/square centimeter, and mW/cm2 is read as 1 milliwatt/1 square centimeter. Generally speaking, the main sources of ultraviolet light used in UV curing are UV mercury lamps and UVLED curing lamps. Before selecting UV curing equipment, you need to make a reasonable selection based on the wavelength required for the UV glue, curing speed, glue thickness, glue area and other factors.

During the curing process of UV glue, if the UV energy of the cured UV glue is too large or too small, it will lead to a decline in the application function after curing. The most direct negative effect of excessive curing is the occurrence of explosions, wrinkles, dry cracks, etc. If the curing energy is too small, it will lead to incomplete curing and affect the bonding effect. Therefore, before using UV glue, you need to screen it according to the actual situation and choose the appropriate curing equipment.

UV glue has many advantages. It cures quickly and can be cured in a few seconds or even dozens of seconds. Shenzhen Yongcheng has many successful cases in UV glue curing.
