Service Details

Description

SQ-720003 One-component UV light hardening liquid, mainly used for hardening the surface of PC, PET, PMMA, PC/PMMA composite sheet or film. It can be coated by spraying, drenching coating, 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 and excellent wear resistance. It can be used to make texture decoration and shell molding of mobile phones, notebook computers, home appliances and other products. The product has high hardness, good chemical resistance, high transparency and stain resistance, and steel wool resistance 1000-3000 times.

Construction technology

1. The commonly used coating methods for UV wear-resistant hardening fluid are spraying, shower coating, and roller coating. Please avoid exposure to sunlight;

2. The product does not require any pre-treatment (including dilution). It is recommended to shake before coating to make the dispersion more even;

3. When performing shower coating, the nozzles of the shower coating equipment should be sprayed from the same horizontal line from left to right. Please refer to the equipment manufacturer's instructions for the specific process;

4. After the shower coating is completed, keep the plate running vertically for about 2 minutes to allow the surface to evaporate and level, then enter the 60-70°C drying tunnel and keep it vertically heated for 5 minutes;

5. After heating, enter the UV curing lamp area for routine curing. The specific curing time is recommended to be adjusted according to the energy of the lamp. If conditions permit, the time can be extended appropriately, which will help improve the hardness of the film layer; (The energy of the UV curing lamp during the test experiment was 2000W. Lamp tube length 30cm)

6. After curing, cool the plate to room temperature and then measure its performance directly;

7. Please clean the equipment thoroughly with organic solvent after curtain coating.
