UV is the abbreviation of the English Ultraviolet Rays, that is, ultraviolet light. UV glue is the UV curing adhesive. Ultraviolet (UV) is invisible to the naked eye. It is a section of electromagnetic radiation outside the visible ultraviolet light, with the wavelength in the range of 10~400nm. Therefore, it can be called UV glue or shadowless glue or UV curable glue; After curing, there is no blocking of light and light transmittance; For bonding glass, transparent material; UV adhesive is in the form of a single component. The surface can be cured in a few seconds under ultraviolet light, and the internal curing time takes several hours. Transparent UV glue for mobile phone keys, UV glass shadowless glue, transparent plastic UV glue, UV shadowless glue for clocks and watches, UV shadowless glue for glass furniture (UV light fixing glue), UV shadowless glue for crystal images, UV shadowless glue for crystal crafts, UV shadowless glue for LED, UV shadowless glue for laminated glass panels, UV shadowless glue for surface coating, and UV shadowless glue for optical lenses.
Main applications: touch panel, LED, solar panel packaging, electronic wiring reinforcement sealant, silicone rubber keys, dispensing needles, medical needles, infusion tubes, optical lenses. It can be used for bonding between glass and metal, glass and plastic, and between glass. It is quite similar to instant glue. After dispensing, it can reach a certain strength within a few seconds after being exposed to UV light, but it can have a relatively long operation time. Even if it is wrong, it can still be corrected before light hardening.
2、 Main performance characteristics
● Advantages:
1. Fast curing and controllable reaction; Solvent free;
2. It is suitable for automatic operation. It is quite similar to instant glue. After dispensing, it can reach a certain strength within a few seconds after being exposed to UV light, but it can relatively have
Long operation time, even if the point is wrong, it can still be corrected before light hardening;
3. Wide range of bonding materials, high bonding strength, structural bonding and wide application;
4. Excellent optical performance; The glue is colorless and transparent, and the light transmittance after curing is>90%. It is called shadowless glue;
5. Rapid hardening, no heating, hardening, no operation time limit, easy storage;
6. Excellent weather resistance, no yellowing;
● Disadvantages:
One side of the adherend is transparent, and equipment is required for complete curing.
3、 Product specification
Various specifications, multiple choices (viscosity from 30cps to 20000cps, etc.), according to different applications, the corresponding viscosity and other performance characteristics can be used
Preparation.
An adhesive composed of chloroprene rubber, which has good electrical properties and thermal resistance. It is cured by solvent volatilization at room temperature, and has the function of bonding and fixation. As long as a small amount of pressing is applied, it will show a strong bonding force.
Main features:
● High thixotropy, with filling and sealing effects
● Less wire drawing, no sagging, and can be used for various bonding
● Flame retardant grade shall conform to UL94 V-0 [E351581]
● Temperature resistance range: - 30~130 ℃
● Comply with EU RoHS environmental regulations
