Improving bonding and paint adhesion

Plasma process is Dry repeatable and environmentally friendly.

Product can be cleaned, etched and primed all in a single 3 step process.

Parts from powder to large auto parts can be handled.

What is needed for good bond strength?

  • Compatibility between the adhesive and the surface of the work piece.
  • Maximal area of intimate contact between the surfaces of the work piece and the adhesive or paint.
  • To achieve all this with minimal or no damage to the surface plasma bonding/painting preparation is an excellent option. It offers a one-step safe and environmentally friendly controlled process for complex parts or bulk goods.

What advantages can plasma processing offer?

Q and A about using Plasma to improve adhesion and bonding.

Small area footprint. One plasma system can complete the stages needed to prepare for painting or bonding. Saving floor space.

Efficiency. Multiple consecutive processes are possible without removing the product. One or thousands of items can be processed at the same time.

Low maintenance costs

No waste disposal costs.

Plasma system suitable for preparing products for painting or adhesion


  • The process is programmable and recorded.
  • The process is in an enclosed controlled environment.
  • The small amounts of process gas used are always fresh.


  • The process is both safe and environmentally friendly.
  • The process gas is used in very small amounts. Especially when compared to Atmospheric plasma.
  • No aggressive fluids or hazardous waste. It is a dry process.
  • No problems with Ozone.

Any combination of:

You only need to touch the parts once. The process can be programmed to clean, etch, and prime. With no interruptions, with each step of the process being recorded for quality assurance.

The different process gases are connected to the chamber and automatically selected as needed.

Cross cut test

Standard test for determining the adhesion of paint to a substrate as detailed in DIN EN ISO 2409 or ASTM D3359-02.

LABS test

A Germany term for paint repelling surface test. Often referred to as the orange peel effect.

English translation: Paint-Wetting Impairment Substances (PWIS)

Plasma etching before and after etching of POM

Tensile strength tester and Microscope

The load required to break the bond or peel paint can be measured.

After destructive testing the breakage pattern of the bond can be evaluated. To observe if the breakage was cohesive or adhesive for example.
