Paint common problems and solutions

1, curing equipment (lights) use a long time, lack of illumination or speed too fast.
Long product storage time or initiator failure. Excessive solvent addition or solvent boiling. Replace the UV lamp or a moderate amount of slowdown to allow the unit to operate under rated conditions.
Products should be used within the warranty period. If they exceed the shelf life, they should be delivered to the manufacturer for processing.
The product should not be added with solvents. If necessary, it should be conducted under the guidance of the manufacturer's technician.

2. The product has improper storage of gel points. The production environment has insufficient UV protection.
Products should be stored away from light, exposed under UV light, and exposed to sunlight.

3, coated product surface rolling marks (orange peel)
The temperature of the production environment is too low or the viscosity of the product is too large. The equipment roll gap is too large. Improve the process. Heat up the product or contact the manufacturer to change the product to a suitable viscosity.
Adjust the roller distance so that it reaches the proper distance.

4. There is a bubble system on the surface of the product that is unstable. There is a leakage phenomenon. Add too many low-boiling solvents. Check the system before production to ensure the tightness of the feeding system.
The product should not be added with solvents. If necessary, it should be conducted under the guidance of the manufacturer's technician.

5, dust on the surface of the product production equipment dust is not good.
The product is contaminated.
During the production, the feeding system, coating roller and drying equipment should be kept clean.
Mixing is strictly forbidden between products.

6, paint film surface decoating substrate surface is contaminated.
The selected product is not appropriate.
The substrate for production should be kept clean and dry, and degreasing and dust removal should be performed when necessary.
UV curing products have a strong specificity, and they are used correctly according to the needs of production.

7. Poor adhesion of the film The insufficient irradiation intensity of the UV lamp results in insufficient curing.
The substrate surface is contaminated.
Diluent was improperly selected.
The selected product is incorrect.
The illuminance of the UV lamp is checked, and if the ratio is significantly reduced or seriously unstable, the lamp should be replaced in time.
The substrate for production should be kept clean and dry, and degreasing and dust removal should be performed when necessary.
The product should not be added with solvents. If necessary, it should be conducted under the guidance of the manufacturer's technician.
UV curing products have a strong specificity, and they are used correctly according to the needs of production.

8, the gloss of the paint film deviation UV light intensity and speed deviation.
Diluent is not properly selected.
Adjust the speed and luminaires to allow the equipment to operate under rated conditions to ensure product quality.
The product should not be added with solvents. If necessary, it should be conducted under the guidance of the manufacturer's technician.

9, the surface of the product is sticky or oily precipitation UV lamp irradiation intensity is not enough to lead to insufficient curing.
Diluent was improperly selected.
The illuminance of the UV lamp is checked, and if the ratio is significantly reduced or seriously unstable, the lamp should be replaced in time.
The product should not be added with solvents. If necessary, it should be conducted under the guidance of the manufacturer's technician.

10, poor adhesion of paint or wrinkle phenomenon Equipment (lights) use a long time, lack of illumination or speed too fast.
The product has been stored for a long time or the initiator has failed.
The amount of solvent added is too large or the boiling point of the solvent is high.
Replace the UV lamp, or moderately slow down the speed so that the equipment operates under rated conditions.
Products should be used within the warranty period. If they exceed the shelf life, they should be delivered to the manufacturer for processing.
The product should not be added with solvents. If necessary, it should be conducted under the guidance of the manufacturer's technician.
