When many people consult about uv glue, they mostly ask such questions as: How long can uv glue cure? Under what conditions should uv glue cure or how can uv glue cure quickly, and so on. Today, in order to solve your problems, I have asked all the technicians in our company one by one. The following is the method for making uv glue cure quickly that I have sorted out.

1. The coating of uv glue should not be too thick

The thickness of the UV adhesive coating plays a crucial role in the curing of the UV adhesive. If the coating is too thick, the drying time will be relatively long under the illumination of a light source of the same power. On the one hand, this affects the drying of the UV adhesive; on the other hand, it will cause the surface temperature of the substrate to be too high, resulting in poor surface gloss of the product.

2. Uv lamp curing

When curing with ultraviolet lamps, an appropriate interval distance should be maintained. The optimal curing distance between the UV LED and the surface of the illuminated object is 1-2 cm. However, depending on the different curing substrates, the distance is generally around 25px.

3. Curing speed of uv glue

According to the differences in substrate, coating, curing interval, etc., adjust the curing speed of the equipment appropriately. If the curing speed is too fast, the UV adhesive on the surface of the substrate will become sticky or the surface will be dry but the inside will not. Slow operation speed will cause the surface of the base material to age.

The above is the method for rapid curing of uv glue that has been compiled and sorted out. I hope it can be of some help to you.
