The SCHERDEL Sur­face Fin­ish­ing Divi­sion regards itself as a prob­lem solver and spe­cial­ist in the field of cor­ro­sion pro­tec­tion by using zinc flake coatings.

DELTA-PROTEKT® KL100 resp. KL120 and DELTA® TONE 9000 are base coats which pro­vide an inor­gan­ic micro lay­er con­sist­ing of zinc and alu­mini­um flakes. Dur­ing the ther­mo­chem­i­cal trans­for­ma­tion process the com­po­nent is giv­en a coat­ing with a sil­very metal­lic sheen which pro­vides excel­lent cor­ro­sion resistance.

Due to the self-devel­oped machin­ery, the Sur­face Fin­ish­ing Divi­sion has many pos­si­bil­i­ties to com­ply with the require­ments of the com­po­nents with regard to cor­ro­sion pro­tec­tion and geometry.

Coat­ing characteristics:

  • cha­tod­ic pro­tec­tion effect
  • bar­ri­er effect pro­vid­ed by zinc and alu­mini­um flakes
  • bind­ing sys­tem reacts with the base
  • cemen­ta­tion of the coat­ing when sub­ject­ed to corrosion

Coat­ing Processes:

  • spin­ning process with bulk material
  • spin­ning process with heavy or com­plex parts in baskets
  • spin­ning process with parts in bas­kets sus­pend­ed on racks
  • spray­ing process
  • par­tial spray coat­ing process

The coat­ings with­stand tem­per­a­tures up to 150/180 degrees Cel­sius (short-term even high­er), are envi­ron­men­tal­ly friend­ly and con­tain no heavy metals.
