Chrome-Free Etch



evolve™ is the first production-proven chromium-free etching process for plating on plastics. Successfully used in mass production across the Americas, Asia, and Europe, evolve delivers high quality chrome parts to customers, while bringing production efficiency, safety, and regulatory compliance to facilities.

Operational advantage

evolve is compatible with most current plating lines. With its wide working window, the evolve process is suitable for plating a wide range of complex geometry parts.

Exceptional adhesion

evolve demonstrates higher peel strengths when compared to standard chrome etch, surpassing even the most stringent adhesion performance specifications.


evolve chrome-free etching process is well suited for ABS, ABS/PC, and selective plating (used in automotive, sanitary, and building hardware applications), as well as PP (commonly employed in the cosmetic industry).

We are committed to delivering safe and sustainable pre-treatment solutions for plating on plastics applications. Our innovative evolve™ and evolve BOND™ technologies offer safe, reliable, and future-focused Cr(VI)-free etching solutions that meet today's regulatory requirements while preparing you for the future. 

Process Steps

evolve™ Cleaner (Optional)Removes general dirt, soils, and fingerprints leaving a clean plastic surface
evolve™ Pre-etchPrepares the plastic surface and ensures uniform pre-etching
evolve™ EtchPatented etching solution that ensures maximum adhesion of the subsequent metallic layers
evolve™ NeutralizerRemoves any trace of etching solution from the fully water-wetted surface of the plastic substrate
evolve™ ActivatorA stable colloidal palladium activator catalyzing rapid coverage by an electroless nickel deposit
evolve™ AcceleratorExposes the activator core, ensuring rapid initiation in the electroless process
evolve™ Electroless NickelHighly stable system depositing a conductive nickel layer in preparation for electroplating
evolve™ InhibitorIncorporated into the stripping line to prevent rack metallization, used after each plating cycle

Sustainability has never looked so bright

evolve™ and evolve BOND™ processes successfully replace conventional etching chemistry and meet current and pending environmental regulations. These processes improve worker safety and deliver high-quality finishes, all while reducing worries about supply chain sustainability.
