As a material widely used in construction, industry, automobiles, home appliances and other fields, coatings have many types and different functions.
What is Coatings and Paints?
The main difference between coating and paint is that coating emphasizes the thin layer covering the surface of the object. What we usually call varnish and paint are both called coating, while paint emphasizes the ability of the thin layer coated on the surface to impart surface color. So, generally speaking, coatings is a general term that covers paints.
The following is a detailed introduction to classifying coatings:
1. Classification by coating form
Water-based paint: Paint that uses water as a diluent, such as latex paint.
Solvent-based coatings: Coatings that use organic solvents as diluents, such as paint.
Powder coating: Coating that exists in the form of solid powder and needs to be heated, melted or solidified during construction.
High-solids coating: A coating with a higher solids content that will form a thicker film after application.
2. Classification according to construction methods
Brush coating: suitable for construction on small areas or complex surfaces.
Spray coating: suitable for large-area, high-efficiency construction, such as building exterior walls, automobiles, etc.
Roller coating: suitable for construction on flat surfaces, such as floors, walls, etc.
Dip coating: Dip the workpiece into the paint, suitable for small workpieces or situations that require full coating.
Electrophoretic coating: The electrophoretic phenomenon is used to deposit coating on the surface of the workpiece, which is suitable for coating metal surfaces.
3. Classification by function
Decorative coatings: used to beautify the surface of objects, such as latex paint, wallpaper, etc.
Anti-corrosion paint: used to prevent objects from being corroded, such as metal anti-corrosion paint, ship anti-fouling paint, etc. VC Copolymer MP resins can be a good choice for improving anti-corrosion of paints.
Conductive paint: Paint with conductive function, such as conductive paint, electromagnetic shielding paint, etc.
Anti-rust coating: Coating used to prevent metal from rusting, such as anti-rust paint, primer, etc.
High-temperature-resistant coating: Coating that can maintain stable performance in high-temperature environments, such as fire-resistant paint, high-temperature insulating paint, etc.
Thermal insulation coating: coating that can reduce the surface temperature of an object, such as reflective insulation coating, radiation insulation coating, etc.
Fire retardant coating: coating with flame retardant or fire-resistant functions, such as fire retardant paint, fire retardant coating, etc. iSuoChem can supply Fire retardant additives--Flame retartant
Waterproof coating: Coating that can prevent moisture penetration, such as waterproof paint, waterproof mortar, etc. iSuoChem can supply some waterproof resins or additves to improve the waterproof of coatings.
4. Classification by use
Architectural coatings: used for coating internal and external walls, floors, ceilings, etc. of buildings, such as 1-latex paint, interior wall coatings, exterior wall coatings, floor coatings, etc.
Automotive coatings: used for automotive surface coating, such as automotive paint, primer, etc.
Home appliance coating: used for coating the surface of home appliances, such as refrigerators, washing machines, etc.
Wood coating: used for coating wood surfaces, such as wood paint, wood oil, etc.
Bridge coating: used for coating bridge structures, such as bridge anti-corrosion paint, bridge deck waterproof coating, etc.
Plastic coating: used for coating plastic surfaces, such as plastic paint, plastic ink, etc.
5. Other categories
Fluorocarbon coating: coating with excellent weather resistance, corrosion resistance and self-cleaning properties.
Ink varnish: Varnish used to coat the surface of printed matter, which can increase the wear resistance and gloss of printed matter.
UV curing coating: coating that uses ultraviolet irradiation to quickly cure the coating and is suitable for high-efficiency production lines.
Coil coating: Coating used for surface coating of coils, such as aluminum-plastic panels, PVC coils, etc.
Colorful paint: Paint that can form a variety of colors and textures, such as colorful imitation stone paint, real stone paint, etc.
Marking paint: Paint used for road markings, parking lot markings, etc., such as hot melt marking paint, normal temperature marking paint, etc.
Epoxy coating: A coating with epoxy resin as the main film-forming substance, which has excellent corrosion resistance, wear resistance and adhesion.
Ship antifouling coating: used for coating the underwater parts of ships to prevent the adhesion and pollution of marine organisms.
Insulating paint: coating used for the insulation of electrical equipment, such as motor insulating paint, cable insulating paint, etc.
Polyurethane coating: A coating with polyurethane as the main film-forming substance, which has excellent wear resistance, weather resistance and decorative properties.
The above is a detailed introduction to the classification of coatings. Different types of coatings have different characteristics and application scenarios. Choosing the right coating is crucial to ensuring the coating effect and object performance.
