Variety of coated fasteners

Specialists in multifunctional coatings and finishing systems

Good Coverage. As specialists in multifunctional micro-layer corrosion protection systems, Dörken develops and manufactures extremely effective surface protection coatings for the automotive and other industries. The company works with users, coaters and plant engineers worldwide on all matters concerning applications. Whether it?s a new part, a specification, application technology, parameter adaptation or equipment design, Dörken provides the right combination of sound professional expertise and experience from numerous worldwide projects to implement a sound, first-class solution to its customer?s problems. The company is also sensitive to the environment and has refrained from using harmful chromium VI since 1980. Our certified quality and environmental management system ensures consistent development and production according to current standards. Dörken generates a constantly growing pool of knowledge with the main focus on practical solutions to coating applications. Dörken micro layer corrosion protection system, trademarked under the name Delta® MKS, offers a complete line of engineered coatings developed to provide the fastener industry with the optimum performance in corrosion protection, consistent torque/tension values and resistance to chemical attack. Products include: Delta-Protekt® Series?Inorganic basecoat and topcoat systems, including the KL 100 Series?inorganic basecoat suitable for steel, steel with a suitable passivation, iron and steel castings. The VH 300 Series?specially designed as a topcoat for zinc-flake systems. The VH 350 Series?topcoat for electroplated zinc and zinc alloys with a suitable passivation, stainless steel, aluminum and its alloys with a passivation and magnesium with a passivation. Delta-Tone® Series?Inorganic zinc-flake basecoat system suitable for steel, steel with a suitable passivation, iron and steel castings. Delta-Coll® Series?Inorganic topcoat system for electroplated zinc and zinc alloys with suitable passivation, stainless steel, aluminum and its alloys with a passivation and magnesium with a passivation. Delta-Seal® Series?Organic topcoat systems engineered for compatibility with zinc-flake systems, electroplating systems, mechanical zinc, steel with a suitable passivation, aluminum and its alloys with a passivation, stainless steel and zinc die cast. Dörken products are not limited to fasteners and stampings, but are also used in a wide variety of special applications. Delta-Flex® S organic topcoat for electroplated zinc alloys enable the coated part a high degree of shaping and bending. Delta-Seal® FAN organic black topcoat for aluminum rivets enables deformation of the substrate, after coating, with no loss of topcoat. Dörken coatings are accepted by OEMs worldwide because they are environmentally compatible systems that are known not to contain carcinogenic, mutagenic, terratogenic, cadmium, lead or chrome VI products in the coatings. Dörken products may be applied utilizing dip-spin, dip drain or spray techniques depending on part geometry. Product is distributed globally via a network of licensed applicators. Product development and manufacturing are certified in accordance with DIN EN ISO 9001 standards.
