The electroplating degreasing process has always been a crucial part of the PVD coating prelude, which has a significant impact on the surface quality and operational efficiency of the electroplated workpiece, as well as the cleaning of the release agent generated during injection molding. Oil stains in the UV vacuum coating process can lead to poor adhesion of the coating, resulting in peeling or foaming, oil spots, and other adverse phenomena. The application of electroplating degreasing agents is to disperse and cover oil stains to solve adverse problems.
1. What is an electroplating degreaser?
The electroplating degreasing agent is mainly composed of modified linear acrylic acid copolymer as the main component, and is a base coating type treatment agent with hydrophilic groups. It contains special functional groups and has high surface activity. It undergoes hydrolysis reaction with the grease (release agent, guide oil, etc.) on the surface of the substrate, which can remove oil stains, shrinkage holes formed by the primer of the treatment agent, and oil spots, oil pits, and other phenomena caused by oil stains.
What is the function of electroplating degreaser?
The function of electroplating degreaser is to hydrolyze and cover the oil stains on the surface of the electroplating substrate. Good surface activity can also increase the adhesion between primers. Wet spraying can be used to solve problems such as oil spots and oil spots. In addition, it can also effectively cover defects such as injection molding material bonding lines, improving the yield and production efficiency of electroplating.
3. What fields are electroplating degreasers suitable for?
The application of electroplating degreasing agents in the industrial electroplating field is very extensive, mainly focusing on UV vacuum coating for electrical decoration, UV vacuum coating for tools, UV vacuum plating for daily beauty, UV coating for decoration, and UV vacuum coating for wine packaging, etc.
4. How to use electroplating degreasing agents?
The process of using electroplating degreasing is in the pre-treatment process of the entire electroplating process, where the substrate workpiece - electroplating degreasing agent - UV primer - UV topcoat. The spraying of oil stain treatment agents is generally 3-5 μ Bake at 60 ℃ -70 ℃ for about 1-5 minutes for adhesion.
Based on the above understanding of the working principle, application fields, and precautions of electroplating degreasing agents, it is added that their main application substrates in the actual vacuum electroplating industry are ABS, PC, ABS+PC, TPU, etc. So a good solution for oil removal should be easy to use and efficient. Compared to white electric oil and oil removal powder, it has high operability, strong safety, and fast oil removal efficiency.
