Spray Chrome Plating Activator – technical basis for stable metallization
The WT-DIRECT Spray Chrome Plating Activator is one of the most critical steps in the entire spray chrome plating process. It creates the reactive surface on which the metallization with A1/A2/B can proceed evenly, in a controlled manner, and without yellowing . Thanks to its specially formulated composition, the activator ensures defined surface energy, wetting, and reactivity – the prerequisite for mirror-like, professional-quality chrome finishes.
Technical advantages of the WT-DIRECT activator
- Defined surface activation – sets the required surface energy for metallization.
- Stable redox conditions – ensures a controlled reaction window of A1/A2/B.
- Minimizes yellowing and incorrect reactions – reduces typical defects such as grey haze, spots or yellowing .
- Designed for WT-DIRECT systems – optimized for WT-DIRECT basecoat, A1/A2/B, deionized water & preservative lacquer .
- Process-reliable and documentable – reproducible activation quality for series production & industry .
In practice, the activator determines whether the metallization process is uniform, complete, and clear – or whether matte patches, islanding, and color shifts occur. The WT-DIRECT activator creates a defined, reactive surface that is precisely matched to the subsequent A1/A2/B components .
In combination with deionized water with very low conductivity , the appropriate WT-DIRECT basecoat system and the correct process parameters (temperature, spray distance, application quantity, dwell time) a stable, technically controllable metallization system for mirror-clear chrome finishes is created.
Especially in professional applications – automotive, interior, design parts, industrial components – the activator secures the basis on which the quality of the entire coating is determined.
Frequently asked questions about the WT-DIRECT Spray Chrome Plating Activator
How can I tell that the activation is correct?
A correctly activated surface exhibits uniform wetting behavior , with no "fish eyes" or dry patches. The metal builds up evenly, without grey or yellowish areas.
Can incorrect activation cause yellowing or stains?
Yes. Under- or over-activation can lead to a yellow tint, a gray haze, or an uneven surface. The WT-DIRECT activator is formulated to provide a stable process window – when used correctly.
Is the activator suitable for plastic, metal and GRP?
Yes. In conjunction with the appropriate WT-DIRECT primer system, the activator can be used on plastic, metal, GRP, wood and painted surfaces .
How important is demineralized water in combination with the activator?
Very important. We recommend using demineralized water with very low conductivity (< 2 µS) to avoid distorting the reaction between the activator and metallization.
Can I also use the activator in third-party systems?
In many cases, yes. Correct spraying technique, contact time, and process control are crucial. The best results are achieved with WT-DIRECT system technology .
Is there technical support available for process optimization?
Yes. WT-DIRECT offers manufacturer support, process analysis and practical recommendations to optimally coordinate activation and metallization.
Conclusion: Professional chrome plating is impossible without the right activator.
The WT-DIRECT Spray Chrome Plating Activator is more than just an intermediate step – it's the technical foundation for clear, mirror-like chrome finishes without any yellowing. Those who cut corners or improvise here risk rejects, customer complaints, and unstable processes.
Rely on the WT-DIRECT activator – for reproducible metallization, stable processes and visible premium quality in every component.
