Various surface treatments for your fasteners.
Surface treatment is important for the durability, sustainability and quality of products. Surface treatments are often necessary in order to deliver an optimal product. Surface treatments are mainly done for corrosion resistance. Below are a number of frequently used surface treatments that we offer.
Hot-dip galvanizing ensures that a powerful alloy is created between steel and zinc, surrounded by a layer of pure zinc. The galvanized surface then shows the zinc crystals.
Hot-dip galvanising gives a layer that is highly resistant to corrosion.
Electro-galvanizing is a way of coating steel with a thin layer of zinc. Using electrolysis, zinc ions are deposited on the product. The resulting coating is shiny, hard and corrosion-resistant.
Nickel plating provides a harder, more wear-resistant and corrosion-resistant surface. It is also easy to solder and chemically resistant. Nickel-plating ensures an even coating over the entire product.
Anodizing is a surface treatment to coat aluminum with an oxide layer. This is done by means of an electrolytic treatment. The oxide layer is hard, porous and wear-resistant. The corrosion resistance can then be improved by sealing the pores.
Chromium plating is often used when anodizing is not possible. Chromium plating is also used when a product needs protection against corrosion, but at the same time needs to be electrically conductive.
A zinc-flake coating protects your products against corrosion for a long time. The combination of zinc and aluminum in a polymerized cross-linked organic matrix ensures corrosion protection that is many times higher than that of a pure zinc layer of equal thickness.
GEOMET is a non-electrolytic waterborne zinc flake coating system, which provides very high corrosion protection in thin film thicknesses in an environmentally friendly manner.
PTFE stands for polytetrafluoroethylene and is the best known NON-stick coating among all coatings. It is a very thin layer that can withstand very high and low temperatures. In addition, it is also resistant to chemicals.
Xylan, also a PTFE coating, is based on an organic solvent and was developed in the early 1970s primarily for coating fasteners and provides great protection against corrosion.
Our specialists will be happy to help you with any surface treatment required for the materials of your project. If another surface treatment is required, we can also supply it. Please contact our product specialists for the possibilities and advice.
