A Brief Discussion on the Possible Problems Encountered in Glass Adhesive UV Adhesive
2021-07-12 2274
Despite the continuous development and maturity of UV adhesive technology, the application fields and applicable materials are also increasing. Glass bonding UV adhesive is still an unshakable and important presence in the UV adhesive system. In the use of UV adhesive for glass bonding, we sometimes encounter some problems.
1. Spot, which means that after two pieces of glass are bonded, there is no adhesive at some of the bonding points. The following two reasons may lead to the formation of spots: firstly, due to the formula of UV glue itself, its leveling performance is not good; The second is to allow air to enter between the glass during the operation.
2. Water seepage occurs during the polishing of the bonding surface. After the glass is bonded to the glass, the bonding side must be polished to make the product smoother and more aesthetically pleasing. The reason for water leakage during polishing may be that the staff did not apply UV glue to the glass edge during operation, or it may be due to poor water resistance of UV glue.
3. When using UV glue, there is a burning sensation on the hands. When operating UV glue, some workers may experience itching, redness, and swelling of their hand skin, which may be caused by excessive amounts of acrylic acid in the glue. This situation often occurs in some low-priced UV adhesives, which may be due to manufacturers using excessive amounts of acrylic acid to minimize costs.
4. UV glue has a strong reaction odor. The main source of UV glue flavor is acrylic acid; Correspondingly, if a UV glue with a stronger reaction odor occurs, it will also have a higher degree of burning on the surface.
5. There are whitening marks on the side of the adhesive. This is also a problem with UV glue itself, which is common in cheap glue on the market.
