GNEE's anti-fingerprint treatment is to use a roller coater to apply an organic coating with anti-fingerprint effect on the surface of the galvanized layer. It is mainly used in high-end home appliances, especially computers, video products, OA, IT and other aspects.
The production process has been improved from the traditional two-step method of first passivation (electrolytic passivation or reactive passivation) and then roller coating to a one-step roller coating method or a two-step roller coating process of secondary roller coating; the chromium-containing anti-fingerprint treatment has been changed to a chromium-free environmentally friendly anti-fingerprint treatment.
Our products have high requirements for the conductivity, corrosion resistance, scratch resistance, alkaline washing resistance, baking yellowing resistance, solvent resistance, blackening resistance, etc. of the fingerprint-resistant film. Self-lubricating steel plates have high requirements for the lubricity and mechanical properties of the strip steel. The requirements for the plate shape and surface quality of the substrate are very high. Contact us to get the latest price of the product.

Advantages of electrogalvanized products
1. The coating has good uniformity, the control accuracy of the zinc layer thickness is high, the surface is delicate, and it is very suitable for the requirements of high-quality coating; there are various post-processing methods.
2. The thickness control range of the coating covers a wide range from thin to thick 3~90g/m2, meeting the anti-corrosion requirements of various products from home appliances to automobiles; saving zinc resources.
3. Good processing and welding performance (spot welding, laser welding).
4. It can easily produce single-sided plated products to meet special application requirements.
