UV treatment for surface treatment of plastic injection parts
UV plastic injection molded parts is a kind of surface treatment technology, the surface of the general plastic injection molded parts, after UV treatment can make the product surface effect more bright, and it is not easy to be scratched, main technological sprayed on the surface of a layer of transparent oil, need to dry after UV light, explain to everybody below the plastic injection molded parts, UV what should pay attention to:
1. Due to the fast curing speed and high production efficiency, UV curing can take 30 minutes;
2. Excellent coating performance, coating in hardness, wear resistance, acid and alkali resistance, salt spray resistance, gasoline and other solvent indicators are very high; Especially its film fullness, luster is particularly prominent;
3 UV paint is the use of light curing process, no pollution in the processing.
4 UV coating is more sensitive to dust, so the processing environment requirements are more strict.
5. Not sun-proof, easy to crack under the sunlight.
6 UV coating time will be long yellow, therefore, in the product appearance requirements of pure white, generally do not recommend the use of UV surface treatment.
