Activation

Increasing the reactivity of a surface by removing or chemically converting inactive substance on the surface. Examples are the removal of metal surface oxides or the formation of polar groups on polyolefines. In many cases, an activation if the necessary precondition for a subsequent coating process to ensure sufficient wetting or adhesion of the coat. The most versatile method is plasma activation. In addition, methods such as flame treatment, corona, or chemical activation baths are available.

Applications
All substrates intended for gluing, coating, painting or printing.

Multi-component die casting, plastic/rubber composites and repainting of inserts
Establishes an adhesive bond in previously
non-combinable components.

Applications

• Multi-component plastic parts
• Rubber-plastic composites
• Foil lamination
• Joining plastic with other material
• Flock coating

“Non-gluable” materials

Plasma activation can make every material gluable, even PTFE.

A good activation can be achieved in the 3D surface in low pressure or partially in atmospheric pressure. You will find a large selection of suitable systems here: Low pressure plasma systems or atmospheric pressure plasma systems.
