Description
SQ-720002 One-component UV light hardening liquid is mainly used for hardening the surface of PC, PET, PMMA, PC/PMMA composite sheet or film. It can be coated by spraying, drenching, roller coating, etc. After the coating is formed into a film, it has good adhesion to the substrate and can protect the surface of the coated material for a long time. The coating process is simple and the production efficiency is high. The coating has good optical properties, no rainbow pattern, high cross-linking density, low curing shrinkage, extremely high hardness, excellent wear resistance, and good anti-graffiti performance. It can be used to make texture decoration and shell molding of mobile phones, notebook computers, home appliances and other products. Good chemical resistance, high transparency, steel wool resistance 50-200 times.

Construction technology
1. The common coating methods of UV wear-resistant hardening fluid are spraying, drenching and roller coating. Please avoid exposure to sunlight;
2. The product does not need any pretreatment (including dilution). Shaking is recommended before coating.
3. When spraying, the nozzle of spraying equipment shall spray from left to right from the same horizontal line,Refer to the instructions of the equipment manufacturer for the specific process.
4. After coating, keep the plate running vertically for about 2min to make it volatilize and level freely,
Then enter the 60-70 ºC oven and keep heating vertically for 5min.
5.After heating, enter the UV curing lamp area for conventional curing, and the specific curing time shall be determined.It is suggested to adjust according to the energy of the lamp. If conditions permit, the time can be extended appropriately.
6. After curing, the properties of the material can be measured directly after cooling to room temperature.
7. After coating, please clean the equipment thoroughly with organic solvent.
Notes
1. This product has been diluted to the solid content and viscosity suitable for coating. It does not need to be diluted before use,
If customers need products with high solid content and can be opened and diluted, our company can provide them according to customers' specific requirements
Corresponding products with high diluent and solid content;
2.This product contains inflammable components. Pay attention to fire prevention during transportation, storage and use.
