Properties

"Soft" topography

This term is to be understood in a figurative sense, as it is still a TOPOCROM® surface. However, the particularity of the Topocrom® surface structure is that it behaves so gently towards fibres, filaments, non-wovens materials and foils, that it is possible to talk of a "soft" surface.

Forming air cushions

Air cushions form in the void areas of the hemispherically-shaped surface structure. Fibres, filaments, nonwovens and foils glide, as if on air cushions, over the guiding parts (e.g., thread guides in high-speed operation). Thus splicing and sticking effects are avoided.
The formation of air cushions avoids sticking of fast moving fibres.

Fluid guiding and wetting properties

This special property allows a film of fluid (water, paint or a lubricant) to be evenly applied to rotating rollers and rolls.

Embossing properties in the rolling process

In the steel industry, Topocrom® coated skin pass rolls are used for the rolling of thin sheets. In this way the structure on the surface is transferred to the sheet metal. These sheet surfaces improve the metal forming results and form an ideal basis for modern paint technology (no filler, no Moiré formation).

Influencing gliding and friction properties

The better gliding properties of TOPOCROM® coated forming tools considerably extend life times. Conversely, feed rolls for sheet metal processing can be coated in such a way that the feeding behaviour is drastically improved (grip effect).

Better ejection of plastic parts from injection tools

TOPOCROM® coated injection tools show much easier ejection of the plastic parts and longer service life.
