Protect Your Metals With The Services Of Powder Coating Los Angeles Contractors

By Sally Delacruz


Powder coating is a way to add strength, stability, durability, and color to your metal pieces. Basically, it is akin to painting the metal but with one key difference, the paint used is in form of powders as opposed to the usual liquid form. No solvent is required to keep the binder and filler in liquid form. You can do the coating yourself or you can use powder coating Los Angeles contractors who offer these services.

There are two main categories of the powders used in powder coating and they include the thermosets and thermoplastics. They have different chemical properties and are used in different scenarios. For example, thermosets are known to reinforce the structural integrity of the component they are applied to. They are more resistant to heat and are more often used in industrial equipment, vehicles, and home appliances.

The powdered material can also be manually dusted on the surface of a metal. Either way, once the surface is evenly coated, the object is cured. This is done by heating the object using either infrared light from a lamp or using an oven. The object is subjected to heat of about 190 degrees Celsius for about 10 to 15 minutes. Once done, the object is allowed to cool.

Powder coating contractors apply this method because it has many advantages. One, the coat process eliminates paint runs and produces a very thick and uniform coats. This is because no solvent is used to make the filler and binder liquid like in traditional paints.

After preparation comes the application. This is normally done using a special electrostatic gun. The gun positively charges the powders, which are sprayed toward the object that is grounded and negatively charged. Different nozzles are used on the gun depending on what type of surface is being painted and the consistency of the paint being used. The powders can also be applied by dusting them onto the surface manually.

Moreover, powdered coat is applied in many areas ranging from heavy industrial equipment to small home appliances. There are two main types of powders that could be used. These are the thermosets and the thermoplastics. Thermosets reinforce the structural integrity of an item. This property will make the item more resistant to wear and tear from heavy use. They are used mainly used in electronics and appliances. This is because they can withstand a high amount of heat.

Once applied, they essentially stay in a permanent form and cannot be remodeled. Thermoplastics, on the other hand, offer strength and flexibility but once applied can be remodeled in future. Also, if they receive a lot of heat they will melt. They are therefore, used for items such as small mechanical parts or other large items.

Here, the object is heated using infrared light or an oven. Temperatures of 190 degrees Celsius are sustained for about 15 minutes and then the metal is allowed to cool. The metal at that point has a very beautiful and professional, high quality finish. Contacting contractors in your area to get a quality metal coat can help preserve the strength and look of the objects.
