1. Non-Chrome Passivation Solution
Non-Chrome Passivation (Chrome-free Passivation) is a technology that creates a chemical conversion layer on metal surfaces without using any chromium compounds . This protective layer increases corrosion resistance, reduces white rust, and improves surface quality before machining or painting . The product contains absolutely no hexavalent chromium (Cr6+) or any other form of chromium, fully complying with international environmental standards such as RoHS and REACH.
2. Passivation of Chrome III (Cr3+)
PrimeCoat® Z80x Series is a line of chemicals developed using Phosphate/Silane technology to provide high corrosion protection while meeting the trend of environmentally friendly production. PrimeCoat® Z80x is designed to replace passivation systems using Chromium VI (Cr⁶⁺), helping businesses transition to chrome-free technology while maintaining effective surface protection and corrosion resistance in a wide range of industrial applications. The product meets RoHS and REACH standards , supporting businesses in reducing the use of hazardous chemicals and aligning with sustainable production practices.
3. Solvent-Replacing Cleaning Agents
MM31® was developed to optimize the entire surface treatment process before and after mechanical machining. After treatment with MM31®, the metal surface is not only completely clean but also forms a conversion coating that offers many benefits such as: increased paint adhesion, resulting in better paint bonding to the metal substrate; reduced peeling during use; improved corrosion resistance, providing better protection against moisture and harsh environments; and reduced rust.
