Manufacturers apply electrostatic powder coating to many types of products
Manufacturers may apply an electrostatic powder coating to many types of products. This type of finish is primarily used on metals ranging from steel to aluminum. It’s also used to finish a variety of consumer goods, from wire shelving to lawn furniture. Electrostatic powder coating is also used on cars and other vehicles, and remains a popular method of finishing exterior metal siding This product may contain a variety of materials, depending on the product and manufacturer. Many include anRead More …
Controlling the moisture content in the MDF is critical
The powder coating process requires an electrostatic charge for the powder to attract to the wood while using a premium grade MDF. This electrostatic charge is created by heating the wood to bring the moisture content to the surface, since it is this moisture that serves as the electrostatic conductor.The adhesion of the powder to the board is so strong that to remove the powder finish from the board it is likely the MDF board substrate will chip off beforeRead More …
What is ABS plastic coating
ABS plastic coating ABS plastic Department of butadiene – acrylonitrile – styrene terpolymer, widely used in the production of home appliances products, housing and automobile and motorcycle parts. Ketone, benzene and ester solvent capable of dissolving ABS plastic, alcohol and hydrocarbon solvent dissolution of ABS plastic, so the general use of ethanol – isopropanol solvent for surface treatment, usually air spraying or electrostatic spraying process for construction . ABS plastic coating paints a wide range of options-based thermoplastic acrylic coatings,Read More …
Some Important factors to polyester coating degradation
Polyester degradation is affected by solar radiation, photocatalytic admixtures, water and moisture, chemicals, oxygen, ozone, temperature, abrasion, internal and external stress, and pigment fading.Out of all these, the following factors, all present in outdoor weathering, are the most important to coating degradation: moisture, temperatures, oxidation ,UV radiation. Moisture Hydrolysis occurs when a plastic is exposed to water or humidity.This chemical reaction may be a major factor in the degradation of condensation polymers such as polyesters , where the ester groupRead More …
Introduction of Fusion bonded epoxy powder coating
Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy based powder coating that is widely used to protect steel pipe used in pipeline construction, concrete reinforcing bars (rebar) and on a wide variety of piping connections, valves etc. from corrosion. FBE coatings are thermoset polymer coatings. They come under the category of ‘protective coatings’ in paints and coating nomenclature. The name ‘fusion-bond epoxy’ is due to resin cross-linking andRead More …
Chromate coating for aluminium surface
Aluminium and aluminium alloys are treated by a corrosion resistant conversion coating that is called “chromate coating” or “chromating”. General method is to clean the aluminium surface and then apply an acidic chromium composition on that clean surface. Chromium conversion coatings are highly corrosion resistant and provide excellent retention of subsequent coatings. Different type of subsequent coatings can be applied to the chromate conversion coating to produce an acceptable surface. What we call as phosphating to steel an iron isRead More …
Powder coating over non-metal products such as plastic wood
Over the last twenty years, powder coating has revolutionized the finishing industry by providing a superior, durable, environmentally friendly finish, particularly for metal products such as appliances, automotive parts, sporting goods and countless other products.However with the development of powder coatings that can be applied and cured at low temperatures,the market has opened to heat sensitive substrates such as plastics and wood. Radiation curing (UV or electron beam) allows the curing of powder on heat sensitive substrates by reducing theRead More …
Advantages of UV powder coating systems
UV powder coating powder formulations consist of:UV powder resin,Photoinitiator,Additives,Pigment / extenders. Curing of powder coatings with UV light can be described as “the best of two worlds”. This new method makes it possible to benefit from the advantages of high cure speed and low cure temperature as well as environmental friendliness. The main advantages of UV curable powder systems are: Low system costs Application of one layer Maximum powder use with overspray recycling Low cure temperature High cure speed HardlyRead More …
