DELTA TONE surface treatment from company SVUM-CZ, MKS, SEAL, PROTEKT, the Czech Republic

Surface treatment of metals is highly required field not only in automotive industry. However, not every company is able to meet strict requirements placed on this field. But our SVUM - CZ company is. Since we use, as the only company in the Czech Republic, an unique method of metal surface treatment DELTA - MKS. Surface treatment of metals using the DELTA MKS method has many advantages. Primarily it complies with new environmental regulations prohibiting use of toxic substances such as hexavalent chromium. Our metal treatment method is therefore absolutely harmless, yet effective. Pluses of this method further include excellent thermal and chemical resistance and also high corrosion protection. Moreover, surface treatment of metals is offered in several variants. So, you can choose treatment exactly according to your needs. And what possibilities of metal surface treatment we offer? - DELTA-TONE - inorganic basic system - DELTA-SEAL - organic finish (it serves for colour marking of surfaces, slows down the white rust growth) - DELTA PROTEKT KL 100 - treatment ensures greater resistance to red and white rust, resistance in salt mist up to 600 hours - DELTA PROTEKT VH 300 - coating based on lithium-silicon-oxide polymer, resistance in salt mist up to 1000 hours - DELTA PROTEKT VH 301 - contrary to VH 300, it contains a sliding agent reducing friction. It is mainly used for threads. This surface finish is possible even for small and precise threads. - DELTA PROTEKT VH 300 and VH 301 GZ - water dilutable, hardening from 80°C. At prolonged exposure to temperature of 200°C, the effect of protection is even better. DELTA – MKS method required not only in the automotive industry. It is also suitable for treatment of furniture fittings, plumbing materials, floatable materials or other small metal parts.

Delta Seal - SVUM-CZ surface treatment of metals, the Czech Republic

Coating materials of Delta Seal line Delta Seal coatings are organic epoxy-phenolic highly crosslinked resins which are used, in thicknesses of 4-10 µm, as Top-Coats on underlayers of Zinc-lamella Delta Tone 9000, Delta Protekt KL 100 coatings, on bases made of galvanic Zn or Zn/Ni, they are used as sealing coatings on stainless steel parts, as well as on parts made of zinc and aluminium or their alloys, also coating of magnesium alloy components is possible. Main functions of Delta Seal coatings: - increase in corrosion resistance in salt fog tests, they slow down white corrosion of zinc - increase in corrosion resistance in sulfur dioxide test according to ISO 6988 (Kesternich test) up to 15 cycles - prevention of contact corrosion - the coating is nonconductive - increase in resistance to automotive operating fluids, further to alkalis and acids - long-term thermal resistance of 150-180°C in combination with Zinc-lamella coatings - constant friction coefficient for threaded parts - color differentiation - basic colours are silver and black, others are available on request, e.g. blue, green, red, etc. Silver and black Delta Seal coatings (GZ version with PTFE lubricant addition) are approved for contact with foodstuffs and drinking water.
