Powder coating is a type of coating that is applied as a free-flowing, dry powder. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, and automobile and bicycle parts.
Galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanization, in which parts are submerged in a bath of molten zinc. Electro galvanizing is another method for this type of coating. Galvanizing protects in two ways:
1. It forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal.
2. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
Gold/Silver Plating is a method of depositing a thin layer of gold/Silver onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating. This method of coating is ideal for jewellery, electronics, decorative items etc.
Xylan Coatings are a family of fluoropolymer coatings designed for use on various types of OEM components and fasteners, including xylan coated bolts to prevent corrosion. Most xylan coatings contain PTFE or other types of lubricants and are applied in thin films. Xylan coating is a dry film lubricant. It provides:
1. Lubrication and controlled friction 2. Wear resistance 3. Heat resistance 4. Nonstick and release properties 5. Can also protect from corrosion
