Suitable coating technology for numerous applications
Different materials and locations place different demands on the coatings. Depending on the area of application, we support you with the right materials. Because only if the substrate is well protected will you benefit from your investment for a long time to come.
With their high dielectric strength, it is Lacquers, silanes, ceramics and composites that are particularly suitable as coating materials for insulating layers. Ceramics and composites impress with their good temperature stability and can be used in a broad portfolio of technical products. Their good thermal conductivity also makes them the first choice, especially for high-voltage applications. Lacquers, on the other hand, are used for complex component geometries, large surfaces or high insulation values.
There are basically two types of corrosion protection: active and passive corrosion protection. With active corrosion protection, the corrosion protection layer is "sacrificed" in the event of corrosion attack for the metal to be protected. For this reason, only base metals (e.g. zinc) are used as a coating for active corrosion protection. Passive corrosion protection refers to all measures that are used to specifically “shield” a metallic component from the influence of corrosive media by applying a barrier layer (e.g. painting, nickel plating, etc.). The performance of the corrosion protection layers can be determined by suitable tests (e.g. salt spray test DIN EN ISO 9227).
Electronic components are usually coated with noble metals such as silver, gold, tin and palladium. In individual cases, rhodium, ruthenium and platinum are also used. All layers have good to excellent contact resistance and have good tribo-electric properties, which is particularly important for contact connections. Silver, hard gold, palladium and palladium/nickel also have good hardness to ensure sufficient abrasion resistance for contacts. In the case of electrical components that are soldered, tin and its alloys are used in addition to the possible materials.
Coatings for wear protection can be produced by galvanic, thermal spray and plasma coatings, among others. Each type of coating brings with it specific properties. For example, they differ in hardness, temperature stability and wear protection efficiency. In order to provide you with the best possible protection for your products, we gather a comprehensive profile of requirements and advise you in detail on the most suitable options for you.
The metallization of non-conductors can be used to generate high-quality decorative elements from lightweight and inexpensive polymer or ceramic materials. Automotive manufacturers and suppliers in particular have great freedom in the construction and design of components through the metallization of non-conductors. In the technical field, too, there are applications for the refinement of plastic and ceramic parts, such as electromagnetic shielding or the adjustment of strength.
