Cleaning and Degreasing for Powder Coating

Posted on: April 30th, 2014 by byersbushblog

For many, the first part of the powder coating process, namely the surface preparation, is the most tedious, as it does not produce any necessarily immediately visible results, making it a tempting one to rush.

This temptation should be resisted, however, as adequate surface preparation is essential to guaranteeing a long-lasting, visually-pleasing finish.

The first step in ensuring a thorough clean is to establish what material you’re working with, as some materials suit some methods better than others, and certain materials e.g. aluminium, can actually be damaged by certain cleaners, so to avoid corrosion, make sure you know what you’re working with.

Here’s the most common method of surface preparation.

Pressure wash

Generally, the first step in preparing a given surface for powder coating is to pressure wash it. This removes any loose debris, and can cut through grease faster than other methods of preparation.

Electric pressure washers are extremely convenient, but are best suited to smaller objects, while gas-based pressure washers take some time to start up, but are a good investment if your surfaces are on the larger side.

Soaking

Here’s where knowing the limits and needs of your material really pay off – the next step is to soak your object with cleaner.

It’s vital that you find the right cleaner for the job. Many manufacturers produce cleaners that are formulated for specific metals, so make sure you’ve got one that corresponds to your chosen metal.

If you’re worried, get hold of some scrap metal, coat it in the cleaner, and allow it to sit for a couple of days. If the metal looks corroded, continue your search for the right cleaner. If not, proceed with the soaking process.

Scrubbing

Once you’ve found the right cleaner, you’ll want to soak your object for 10 minutes before utilizing a soft nylon scrubbing brush to attack any stubborn grease or grime that’s refusing to budge.

The best place to do this is in a dedicated parts washer, but these aren’t necessary pieces of equipment in a beginner’s powder coating kit.

This part of the process can be the lengthiest, and the amount of time it takes will depend on the condition of the original part.

If some debris is reluctant to be shifted, rinse your object, repeat the soaking process, leaving the cleaner on for longer time, and continue scrubbing.

Eventually, all the dirt should give in and scrub off with a little elbow grease.

How to Powder Coat Effectively

Posted on: April 30th, 2014 by byersbushblog

Powder coating is a relatively new phenomenon in the metal industry, but has many benefits that have seen it quickly become a real contender against other finishing processes.

It leaves the coated surface both very resistant to corrosion and is better developed to covering and smoothing surface imperfections. How, then, is it done?

Somewhat surprisingly, powder coating is a very simple process that is completed across three stages, after which, with appropriate maintenance, you’ll be left with a finish that will last an incredibly long time.

Stage One: Preparation

Before you begin the coating process itself, the surface you intend to cover, regardless of what it is, requires substantial pretreatment and preparation.

It can be tempting to rush through this aspect of the process, but doing so will result in a sloppy finish, with bubbling, peeling, streaking and reduced resistance to potential lifespan risks have all been observed when the object being coated has been improperly prepared.

Pretreatment equipment should be used to clean your object thoroughly, so that the powder coating can adhere to the object properly. Steam units, dip tanks, and blasting stations are all examples of pretreatment equipment for surface preparation.

Stage Two: Powder Spraying

Once you’ve prepared your surface, it’s time to spray it! This is usually done with a spray gun that gives the powder an electrostatic charge which allows it to adhere to the surface.

This can be a lengthy process, as some paint will require reapplication, but it’s important to take your time. Furthermore, it’s worth finding the right environment to complete the process in.

Enclosed, clean spaces are best, as they prevent debris from getting stuck in the powder coating, leading to similar problems that an improperly prepared surface would have lead to.

Stage Three: Curing

The final stage of the powder coating process is called curing and sets the powder coating onto the object properly, giving it a healthy lifespan, and making it more resilient.

The coated object is cured in an oven between 325-425 degrees F for most powders, where it melts and bonds to form a rock solid finish.

Once the curing process is complete, the powder coat is finished, and the object to which it has been applied is ready for service.

Powder Coating Equipment for Beginners

Posted on: April 29th, 2014 by byersbushblog

The world of powder coating can look a little daunting to a novice with no practical, first-hand experience of the process, but a beginner’s kit is easy to get hold of and will have you powder coating in no time.

Beginners’ powder coating equipment is generally only made up of three elements, all of which can be acquired with some clever shopping and research into reputable providers.

Here’s what you’ll need to start powder coating.

A Gun

And, no. Not that kind of gun. The one we’re looking for is a powder coating gun.

The most important piece of powder coating apparatus is the gun itself. Guns can be picked up from a number of sources, and a good quality beginner’s one shouldn’t set you back more than around $100.

The gun requires a compressed air source to run properly. Luckily, powder guns are capable of creating full coverage of a surface without requiring high pressure, so a low output compressor should do more than suffice.

“Look for a small compressor that is capable of between 5-10psi.”

Once you have your gun and air compressor, you’re covered for the coating stage of the overall powder coating process. For the curing process, you’ll need a heat source.

An Oven

The final stage of the overall coating process is called curing and is designed to set the powder coat by heating it, causing it to melt and bond, after which it can be removed and cooled to room temperature, revealing a resilient finishing coat that can withstand numerous corrosive or abrasive conditions.

“The curing process can be completed with the help of a basic, domestic oven.”

These can be picked up secondhand from numerous outlets, but it is incredibly important to make sure you purchase an oven specifically for this purpose, and do not split the requirements of your existing household oven to accommodate powder coat curing.

This is because the chemicals burnt off during the curing process can contaminate food, and be extremely harmful in terms of human consumption. If you’re serious about powder coating, you need to splash out on a new, dedicated oven for the privilege.

Furthermore, make sure your oven is spotless, otherwise any debris inside it will quickly become debris embedded into the powder coating, leaving imperfections in the finish and potential weak spots in the durability of the coat.

If you’re looking to get started in the world of powder coating and could do with some pointers, or further information about the process, then contact Byers Bush Powder Coating Inc.

Sandblasting 101 – The Basic

Posted on: April 29th, 2014 by byersbushblog

As more and more people in the metal industry look to more long-lasting solutions to fulfil their need for resilient coating, many are turning to powder coating and its unique benefits.

As one third of the overall powder coating process, surface preparation is key to ensuring a good finish with real longevity.

There are a number of ways to adequately prepare a surface for a powder coat. This article looks at one of most widely-trusted and popular methods: abrasive blasting or sandblasting.

What is abrasive blasting?

Abrasive blasting involves shooting a given media (usually sand, steel shot, glass bead or grit) at the surface being prepared at high velocity in order to shift stubborn grime and other materials that will prevent the powder coating from adhering properly to said surface.

What is used?

Blasting equipment is usually either turbine-based or air-based.

Hand-held systems are subject to the quality of the professional operating them, as they require perfect concentration and expertise to thoroughly clean the surface.

Alternatively, blast cabinets are enclosures designed for abrasive blasting, and the results of the preparation are only dependent on the quality of the equipment itself.

Which standard do I need?

Blast requirements of a surface will depend on its intended purpose, but four grades are recognized officially by the Steel Structures Painting Council as follows:

  • White metal blast: Removes all visible rust, mill scale, paint, and grime. White metal blasts are mostly used for surfaces that reside in environments with a high corrosion risk.
  • Near white metal blast: As before, but removes only 95% of visible debris. Near white metal blasts are most appropriate for materials that are going to be in heavy regular use.
  • Commercial blast: Commercial blast cleaning aims to remove two thirds of visible debris, making it suitable for non-corrosive environments.
  • Brush-off cleaning: The least thorough of all blast standards, brush-off cleaning aims to lightly blast all the material removing all debris except for stubbornly-adhering residue. This is the lightest form of blasting, making it best suited to non-corrosive environments where a lengthy lifespan and strong resilience is not required.
