UV glue curing why the white do? This phenomenon, often appear in the glass industry whitening phenomenon is actually tiny bubbles, UV adhesive layer itself will produce the contraction because the UV glue landline process in uneven layer thickness or hardness is too high, the contraction of the internal stress can not be released, a long time there will be tiny bubbles, that is, we see the whitish phenomenon until the bonding material off.
The way to solve this problem:
First to choose flexible recipe UV glue;
Second bonding layer control uniform;
Third, the initial solid is used when the low-power UV lamps, so that the slower the speed of curing of the glue, after positioning in the use of high-power UV device depth curing, because the the glue curing speed is too fast, will increase the shrinkage of the glue.
