UV curing range: the effective absorption peak is 390 and 460nm, and the absorption is up to 500nm
Packing: 1kg / bag, 1 bag / box, 5 boxes / box
Usage: This product is a kind of UV curing agent, which is mainly used for UV curing of alkyd resin, acrylic resin, silicone resin, epoxy resin and so on
Because the product decomposed in the curing process is colorless or white, it can be used in both light color system and dark color system, and has photobleaching effect
The specific applications are as follows

1 UV paint
It is widely used in the production of plastics, vacuum electroplating, PVC floors, shadow mask boards, automobile headlights, wood floors, cabinet panels, etc
curable resins include epoxy acrylate, polyurethane acrylate, polyester acrylate, polyether acrylate, acrylate polyacrylic acid resin and unsaturated polyester, as well as monofunctional or multi-functional monomers of various acrylate, Addition amount: used alone with other photoinitiators, the recommended addition amount is 0
3-3% (wt / wt)

2 UV ink
The ink has the advantages of less than 100% volatile solvent and no damage to human health due to less volatile solvent content in the ink before and after printing; 2) Ink does not block the screen, which is conducive to the printing of fine products; 3) In printing, do not worry about the damage of solvent to the substrate, the ink quality is stable, the gloss of dry ink film is good, and the ink film has good wear resistance, water resistance, oil resistance and solvent resistance; 4) Instantaneous drying of ink can organize rapid printing production line and greatly improve printing efficiency; 5) Ink saving during printing
Solvent based ink can print about 50 ㎡ per kilogram, while UV ink can print 70 ㎡ under the same conditions
3
UV ink will enter the field of body advertising and banner printing
UV ink has been in the process of development and change, and more and more printing plants begin to use new UV digital printing ink
When in use, the product is mixed with the ink prepolymer to prepare UV ink
The addition amount is about 0
3% ~ 3%
It can be used with other curing agents
The advantage of using this product is deep curing and give full play to the bright color of the ink

3 UV adhesive
UV glue is mainly used in industry, glass crafts, crystal crafts, electronic components (LCD, LCD seal, optical fiber connector, touch panel, SMD, led, electronic cable reinforcement sealing glue, EMI, VCD, optical disc, laser head, touch screen, camera, optical lens, buzzer, horn), watch industry, glass furniture, glass stainless steel, glass aluminum, Bonding of plastic products (PVC, PS, ABS) and other products
The light curing agent of this product has the advantages of fast curing speed and high light transmittance

4 photoresist
This product is used for negative photoresist and is suitable for the production of devices with low integration

5 photopolymerization printing plate, composite material, tooth filler, etc
