Fraunhofer-tested: Improved adhesion on modern PP plastics

Modern vehicles use more polypropylene (PP) parts than ever – bumpers,trims, mirror housings and other exterior components.
PP is lightweight and durable, but it is also a demanding substrate. Staticcharge and dust attraction can interfere with surface preparation and affectcoating stability.

When adhesion issues occur on plastic parts, the coating material isoften questioned first. In practice, the cause frequently lies in surfaceconditions prior to application.

Used as the final preparation step before coating, IONSTAR neutralisesstatic charge directly on the surface. By reducing static-related dustattraction and stabilising paint lay-down, it helps support more consistentadhesion on PP components.

The effect is not a change in chemistry, but improved process stability.
Fewer avoidable defects, less rework, and greater confidence when coatingplastic parts – especially on visible components such as bumpers.

Fraunhofer testing confirms measurable improvements in adhesionperformance on PP substrates under controlled conditions. In daily workshoppractice, this translates into reduced risk during production.

Improved adhesion is ultimately about control: reducing one variable ina process where small influences can have visible consequences.
