Types of Coating Service
The coating services provided by our company mainly include the following types:
Metal Film Coating
Metal film coating is a thin layer of metal applied to a surface to improve its properties. It can be used for a variety of purposes, including making mirrors, improving corrosion resistance, and enhancing optical properties.
Dielectric Film Coating
A dielectric film coating is a thin layer of insulating material that's applied to a surface. It can be used for electrical insulation, optical devices, and more.
Infrared Film Coating
An infrared film coating is a special layer applied to photographic film that makes it sensitive to infrared light, which is invisible to the human eye, allowing the film to capture images based on the infrared wavelengths reflected by objects in a scene, creating a unique visual effect often characterized by bright white foliage and dark skies when used with an infrared filter.
Functions of Coating Service
● Abrasion Resistant - The coating provides resistance to damage by abrasion.
● Adhesive - The coating provides adhesive properties.
● Antireflective - The coating has an anti-reflective property applied to the substrate to reduce glare.
● Anti-slip / Abrasive - Anti-slip coatings produce a textured, abrasive, sticky or roughened surface layer to prevent personnel from slipping and falling on floors, steps, and walkways.
● Chemical Resistant - The coating provides resistance to damage by acids, alkalis, general chemicals and oils.
● Conductive - The coating forms an electrically conductive layer on the substrate.
● Corrosion / Rust Preventive - A type of coating that prevents rust by preventing moisture from reaching the metal or underlying substrate or by providing a sacrificial layer.
● Dielectric - Optical coatings made from dielectric (nonconducting) materials.
● Friction Reducing / Low Friction - Specialty coatings applied to reduce friction between two materials.
● Heat Resistant / High Temperature - Coatings resistant to damage by heat or the coating is formulated for use in high temperature environments.
● Mold Release / Nonstick - Release and nonstick coatings are applied to a substrate to prevent materials from sticking.
● Oil & Grease Resistant - Coatings resistant to degradation when in contact with oils, lubricants, grease and other petroleum fluids. Oil repellent or oleophobic coatings are not wet by oils.
● Porosity / Surface Sealing - Coatings function as surface sealants or porosity sealers. The sealing material can be assisted using vacuum, pressure, and vacuum-pressure impregnation (VPI) techniques or the natural wicking action of the component.
● Protective - Coatings protect substrates from the outside environment, physically and/or chemically.
● Reflective - Reflective coatings consist of mirror like deposits for reflectance of light.
● Waterproof / Water Repellant - Exterior clear finishes that are specially formulated to cause water to bead up on the surface and minimize penetration of water into the substrate.
● Wear / Erosion Resistant - The coating is resistant to wear or erosion. Wear is usually defined as wear produced from a sliding action between two or more components. Erosion is damage or material removal as a result of particle or slurry impact against a surface.
Method of Application of Coating Service
Anodizing
Anodizing is an electrocoating process that involves the use of negatively charged particles to increase the thickness of a metal's natural oxide layer. In the process, the target metal is submerged in a charged electrolytic solution and acts as the negatively charged anode. This creates a buildup of metal-oxide particles on the metal's surface.
Cladding and Hardfacing
Cladding is a process where another type of material is metallurgically bonded to a base metal, usually through a rolling or high pressure process. Usually the base metal is less costly, but less corrosion or wear resistant. Stainless steel clad to carbon steel would be an example of a clad or bimetal material.
Plating
Plating is a process used to deposit a coating onto a metal or conductive surface using a metal salt solution of the metal coating to be deposited. Electroplating requires the application of an electric current, which turns the substrate into a cathode which attracts positive metal ions to its surface. Electroless plating uses a chemical deposition process instead of an electrical current to deposit the metallic layer, and provides a more even plate layer, even on complex geometries.
Sealing and Impregnation
Sealing and impregnation coating processes use vacuum, pressure, vacuum-pressure, and/or wicking action techniques to drive resins or coating materials into parts to seal open porosity.
Thin Film Coating
Thin film coatings play a prominent role in the manufacture of many electrical devices. They are used to apply dopants and sealants to chips and other microelectronic parts. Physical vapor deposition (PVD) and chemical vapor deposition (CVD) are two most common types of thin film coating methods.
