Application fields of UV glue (shadowless glue)

1、 UV glue -- Application in medical supplies

One of the driving forces of the increasing use of UV curable glue is the use of disposable products. UV glue can be used to bond hypodermic needles with syringes and intravenous tubes, and in the use of catheters and medical filters. (medical grade UV glue 3311)

2、 UV shadowless adhesive - Application in glass, handicraft and jewelry industry. UV shadowless adhesive is widely used in glass industry, especially in safety glass due to its excellent optical and chemical properties. Different from the traditional safety glass production time of about 20h, UV shadowless adhesive can complete the bonding process in seconds or minutes, greatly improving the production efficiency and shortening the production cycle. In addition, glass furniture is also an important application field.

UV shadowless glue, in the jewelry, decoration industry, can quickly complete the gem, crystal and other inlay, positioning and so on.

3、 UV glue - the application of UV glue in the electrical and electronic industry has the fastest development speed in the electrical and electronic applications. Its main uses include:

1. Bonding and sealing of smart card and conductive polymer display;

2. Coating and sealing of terminals, relays, capacitors and microswitches;

3. Printed circuit board (PCB) bonding surface components;

4. Bonding of integrated circuit block on printed circuit board;

5. Fixing of coil wire terminal and bonding of parts.

In the same way, the bonding of automobile industry parts usually belongs to this field, and its application covers the assembly of automobile lamp, the bonding of reversing mirror and airbag parts, and the fuel injection system.

4、 UV shadowless adhesive - Application in optoelectronics and information industry. With the continuous development of science and technology, UV shadowless adhesive has great potential in this field, which mainly includes three consumption fields: digital optical disc manufacturing, optical fiber bonding and liquid crystal and polymer display.

1. UV curable adhesive is used in digital disc manufacturing industry, mainly including: coating of reflective film and protective film; sealing cover of DVD packaging, etc;

2. Optical fiber and conductive pumping compound display is also one of the application fields;

3. Liquid crystal and polymer displays are the continuation of LCD technology. Liquid crystal display (LCD) is widely used in electronic devices, such as: watch, calculator; computer monitor; TV screen; camera / clock; tester Reading Panel; automotive electronic instrument panel; personal digital assistant (PDA) display, etc.

The use of UV glue in LCD manufacturing is as follows:

① The photoelectric module is temporarily fixed in position;

② Main board seal;

③ Port seal;

④ Bonding of metal lead terminals;

⑤ Flexible sealing end;

⑥ Bare chip mounting;

⑦ Co directional heterotopic and film bonding, as well as fcog cover coating.

In the manufacture of computer hard disk, the bonding procedure of magnetic head and folding piece is: a small amount of glue is added to the tongue piece at the front end of folding piece, and then the magnetic head is clamped on the tongue piece by the central tool. The adhesive is initially cured by irradiating a certain intensity of ultraviolet light for a few seconds, then taken out from the automatic bonding machine, processed and put into the oven, and then heated and cured at the set temperature, which belongs to the dual curing of ultraviolet and thermal curing.
