Although Imprimantes UV can print patterns on the surface of hundreds or thousands of materials, however, due to the characteristics of different material surfaces, differences in performance such as adhesion and flexibility of UV ink can cause skin peeling and peeling off on some materials, which requires the use of UV coating to solve this problem.
There are currently 6 types of common Imprimante UV coatings on the market:
1、Imprimante UV glass coating:
It is suitable for plexiglass, tempered glass, glazed ceramic tiles, crystal and other glass materials that require special treatment. Currently, there are two types: quick-drying coating and baking. The former can be wiped and left for about 10s to print the pattern, and the latter It needs to be baked in the oven before printing the pattern.
2、PC coating for uv printer
Some hard PC materials usually have poor adhesion! Some PC materials can be printed directly without coating! Generally, imported PVC acrylic panels need to be wiped with PC coating.
3、Imprimante UV metal coating
Metal coating: suitable for aluminum, copper plate, tinplate, aluminum alloy and other materials. There are two types: transparent and white. It needs to be used on the finished product and cannot be used before stamping or injection molding, otherwise the effect will be greatly reduced.
4、Imprimante UV leather coating
Suitable for genuine, leather, PVC leather, PU leather, etc. After spraying on the surface of the leather material, wait for it to dry naturally.
5、Imprimante UV ABS coating
Suitable for wood, PVC, ABS, gypsum, thickened kraft paper, acrylic, PS PVC and other material surfaces. After wiping the coating, let it dry naturally and you can print.
6、Imprimante UV silicone coating
Suitable for silicone and rubber materials. The surface activity is poor and requires flame treatment, otherwise the adhesion will be insufficient. Flame treatment is based on experience. The surface should not be sprayed too thickly, otherwise it will not be easy to dry.
Instructions:
1、The ingredients required for coating include fixed ratio and mixing techniques, which need to be carried out according to the instructions.
2、Once it is found that the coating has chemical reactions such as dissolution and foaming with the UV ink, it is necessary to replace the coating with a more compatible coating.
3、The irritating smell of the coating is generally relatively large, so masks and disposable gloves can be used during the operation.
The types of coatings corresponding to different materials are also different. Do not adapt one coating to other materials.
Coating preservation matters:
1、Place it in a cool, backlit and ventilated place；
2、After use, the bottle cap needs to be tightened in time；
3、Do not press other materials on it；
4、Do not put the coating liquid on the ground.
Usually when users purchase Imprimantes UV, manufacturers will provide matching coatings, molds or varnish and other process solutions based on the user’s product characteristics.
