When many people choose uv adhesives, they usually require that the uv adhesives have fast curing speed, do not turn white after use, leave no marks when bonding, and have a long service life. Many customers use uv glue on transparent materials like acrylic sheets, so they hope that there will be no marks after uv glue bonding, so as not to affect the appearance of the product. So, when using uv glue, what issues should be noted to ensure that the uv glue bonding leaves no marks? Dingxin engineers will answer for everyone.

uv glue can be used for bonding glass to metal, metal to metal, and glass to glass, and it can also be used for bonding electronic product components. When using UV glue to bond large areas or products with high appearance requirements, whether there are traces of glue bonding after bonding is also a concern for many factories that use UV glue. The solutions to this problem are as follows:

When choosing uv glue, we should select relatively thin uv glue. This way, the flow performance of the uv glue is better, which is convenient for leveling after dispensing to expel air.

Second, when we use uv glue for bonding, the surfaces of the two objects to be bonded should be relatively flat so that the gap between them should be uniform.

Thirdly, the operator using UV glue should be proficient, apply force evenly, and after pasting, do not shake it when shining the UV lamp. Finally, the UV glue used must ensure that the manufacturer has undergone degassing, stirring and mixing, etc. before leaving the factory.

When we use uv glue for bonding, as long as we pay attention to the problems mentioned above during the application of uv glue, the products bonded with uv glue will leave no marks.
