How to Improve Adhesion to Helmet Visors Using Corona Treatment
Case Summary
Maas Coating experienced inconsistent adhesion and quality issues with mechanical pretreatment, resulting inwaste and production losses.
With Tantec’s plasma and corona solution, they achieved a stable process and significantly better adhesion.
Result:
✓ High and consistent quality
✓ Less waste
✓ More efficient production
Conclusion:
A solution that works, stable and reliable.
A global manufacturer of helmet visors needed a faster, more consistent, and more sustainable way to prepare surfaces before coating. Their existing process relied on a primer step to secure adhesion — but it was time-consuming, labor-intensive, and involved costly chemicals.
To optimize production, the company integrated Tantec’s RotoTEC-X corona treatment system, specifically designed for the uniform surface activation of curved plastic components. The system ensures even energy distribution and stable surface activation across the entire visor — creating optimal conditions for coating adhesion.
After implementation, the improvements were significant:
- Process time reduced by 92%
- Process cost reduced by 96%
- Remarkable improvement in surface wettability
- Stable and repeatable activation across multiple measurement points
The enhanced hydrophilicity after corona treatment allowed the company to completely eliminate the primer step, cutting out a costly and environmentally challenging part of the process.
Surface stability was confirmed by only a slow increase in water contact angle after 24 hours, demonstrating the robustness of the treatment.
“The RotoTEC-X has become the workhorse of our surface preparation,” the customer notes. “It helped us reduce process time, cut costs, and achieve reliable adhesion without the need for primer.”
Result: Faster cycle times, lower cost, and a cleaner, more efficient surface preparation process.
