Paint This is an economical coating process that can speedily save metal parts from any harm. Paint is able to dry very quickly and it can be apply by making use of brush or with a pump machine. On the other hand, colors of the paint coating can become lighter due to contact with the sun. This type of paint coatings can fragment easily. There is an opportunity to re-paint those parts that had been painted before and re-painting can be done when there is a need to maintain exterior appearance and exposure. Powder Coating With the help of an electrostatic accusation powder coating can be applied to a metal part. Powder coating is an epoxy powder or polyester. This coating is applied by way of charge as said above and after that heated to dissolve and make well the fine particles of power into a consistent covering. As far as the powder coating is concern it is further strong and long lasting when compare to ordinary paint. Power coating is more costly because of it durability. As similar to paint powder coatings can also be produced in a broad variety of colors. Power coating can be applied as a free-flowing and this type of coating is similar to dry powder. There is a major variation in between a usual liquid paint and a powder coating and that is nearly all the powder coating do not have a need of solvent to maintain the ring binder and space filler elements in a form of liquid suspension. The powder could be a thermo set polymer or a thermoplastic and the power coating is usually applied electrostatic ally and after that healed below high temperature to permit this to flow and outline a coat. This type of coating is typically utilized to build a durable finish that is stronger when compare to usual paint. This coating is mostly utilized for covering of metals for example aluminum extrusions, white ware and bicycle parts or automobile also. Galvanization This is an application of a slim coat of zinc to the exterior of a metal element. Often, Galvanized components are found commonly in a dull gray color, but a number of colored procedures are accessible that is occupied by Galvanization. When the zinc mechanically will link with the base metal then it construct a coating that will not peel or break off. Electroplating An electrical current is used in Electroplating to put down a slim coating of metal with the help of a solution top of a metal part. Silver, gold, copper and many other metals are electro planted to recover electrical conductivity and give resistance to ecological special effects or to improve their appearance.
