When Searching For Professional Powder Coating Los Angeles Needs First Consideration

Whenever one needs to perform powder coating Los Angeles should not be left out in the list of places to check out. Powder coating is the process of applying dry powder on surfaces in its free flowing state. Dry powder coat is similar to the normal liquid paint with the exception that the former does not require a liquid solvent to be useful.

Powdered paint can be used to coat several kinds of surfaces ranging from household appliances to automobile parts. More research indicates that other substrates like medium density fiberboards can also be coated through various processes. Besides metals, ceramics and plastics can also be coated using this process. The application process entails three major steps with the actual application being done using electronic guns.

The three major steps involved in application procedure are curing, surface preparation, and actual application. Surface preparation is crucial before application as it removes oil, grease, metal oxides, dirt, welding scales, mold, and dust among other undesired matters. Preparation could be done through different mechanical and chemical methods. The method applied should be determined by kind of dirt concerned, application of the finished product, and size and construction material used on the object.

Chemical treatment entails use of chromates and/or phosphates in spray and/or submersion application. This is performed in multiple stages and involves de-smutting, degreasing, etching, various rinses, and phosphating and/or chromating of the item as the final procedure. Pre-treatment is vital since it cleans and improves the bonding capability of the coat to substrates. Use of chromate compounds is being avoided as they are dangerous to the environment.

The key and most popular way of applying powdered coats onto substrates entails utilizing electrostatic or corona guns. Guns positively charge particles in the paints as they are emitted at the nozzles. Positive particles are then pushed to the substrate by compressed air and/or mechanical mechanisms. Electrostatic charges act to further accelerate particles. There are diverse types of nozzles that could be used to attain certain application requirements.

Another technique of applying powder form paint is known as fluidized bed method. This method entails heating the substrate to very high temperatures and then passing it through an aerated bed filled with the powdered coat. As the paint makes contact with the hot substrate, it melts and sticks onto it. Further heating is necessary to complete the curing process. Fluidized bed method is necessary if the thickness of the coat is supposed to be more than 300 micrometers.

The powdered film can be removed using various chemical compounds like methylene chloride. Other organic solvents are observed to be very inefficient in removing the coat. Methylene chloride is however being replaced by benzyl alcohol because it is suspected to have carcinogenic characteristics. Abrasive blasting can also be used to eliminate the coat. The substrate can still be re-powdered after being cleaned.

When in need of professionally done powder coating Los Angeles is the right place to check out. Companies in this region have high levels of expertise in this process. They can be hired for customized work on any kind of object.
