What is Powder Coating?

Powder coating is a resin based product with different ingredients added for various applications – polyester, epoxy, urethane, or a hybrid mixture. Each offers a unique combination of desirable characteristics:

Providing: Resistance to:
durability wear
resilience corrosion
high-gloss or semi-gloss impact
electrical insulation chemical action
toughness weather

We also offer a moisture-resistant PLASTIC Coating – Great for items with lots of outdoor exposure.

Why should I choose Powder Coating?

If you want a finer quality, longer lasting color finish than what you can get with ordinary liquid paint. Powder coating is the way to go.

Today almost 15% of all protective coatings applied today are powder coating and that number continues to grow. Consumers have grown to expect and request the quality and durability of Powder Coating.

Does Powder Coating prevent rust?

Powder coating is durable and very long-lasting depending on its environment and how the items are used. It is not, however, a rust preventive. Pre-treatment and/or primer coating is helpful for longer coating life.

Can galvanized metal be powder coated?

Yes! Certain pre-treatment or “out-gassing” is required before coating, but both hot dip and electro galvanized materials can be powder coated.

How do I have my items Powder Coated?

  • Remove all plastic, rubber, wood & excess oil or grease from your items.
  • Bring your items to be coated into our facility during business hours.
  • Choose the color you want from the many colors we carry in stock or order a special color.
  • We prep your items, coat them and have them ready for you to pick up on your appointed delivery date.
For auto parts: Remember that we use sandblasting to prepare your parts for coating. You must be sure to thoroughly clean your parts of residual sand before you use them!

Powder Coating

Fast, Cheap and Good

Posted By rickd2015

You have probably heard the phrase, “You can have it fast, cheap or good, but not all three.” When you think about it, there is truth to that saying. But before a business does any one of those, it is important to consider customer service.

As long as we can provide the best in customer service and communication, the other three take care of themselves.

First of all, there is no compromising with GOOD. No matter what your other requirements, we do not settle for second best when it comes to your powder coating.

If you need it FAST, we will not hurry the work, or else it wouldn’t be GOOD. You are asking us to place your work ahead of others’ whose parts are already in line. Expediting work requires that we reschedule our prep and possibly our powder order. We also have to consider whether we will be able to complete all the other jobs we have promised. So, if FAST is a priority for you, that will require an additional fee.

Speaking of fees, if you want CHEAP work, you might want to remember the saying, “you get what you pay for.” For the past 20 years, we have based our pricing on what it costs to provide our customers with the best powder coating we can. It has paid off for us in return customers and our business continues to grow. While you won’t get it CHEAP, you can always count on GOOD. That’s the reason we are still here to serve you since 1996.

At Electro Tech Coatings, we specialize in both household and commercial powder coating jobs of all sizes.

Electro Tech powder coating services have a proven track record of quality and dependability, and we serve San Diego and the surround southern California areas. Our family owned and operated powder coating company has built our business by providing top-quality powder coating services on time and on budget. Call us at 760-746-0292 for free estimates.

Part Preparation

Posted By rickd2015

Whether in the kitchen or in the garage, the key to doing a good job is in the preparation. In the case of powder coating, a clean, etched surface is the ideal way to ensure an even coating. But before we clean and etch the parts we ask that you bring them to us ready to prep. Here are some tips:

  • Disassemble the parts you want coated separately. Assembled parts will be coated as a unit and may not be removable without damaging the coating.
  • Remove all non-metal parts such as:ornaments, plastic adornments. bushings, electrical wiring, feet, pads or webbing.
  • Clean off excess oils or fluids, grease and road grime.

Pot metal and cast parts require additional prep called, “outgassing.” When heated, these metals release gasses that can become trapped in the powder coating as it cures. By pre-heating these items before coating, we hope to reduce or eliminate this, but cannot guarantee a bubble-free finish.

Powder Coating FAQ Powder Coating Process

What Is Powder Coating

Posted By admin

Powder Coating Process

Electrostatic powder coating process is a method of applying electricallycharged powder coating materials to grounded parts. Powder is held to the part by this electrostatic attraction until heat is added to flow the powder together and cure it.

Powder Coating Process

Powder may adhere to the workpiece for several hours. If the uncured powder coat is damaged or blemished during handling, powder can simply be blown off with air or vacuumed and a new coat applied.

Four basic pieces of equipment commonly comprise an electrostatic powder spray coating system. They are the powder feeder, power unit, electrostatic gun, and powder booth recovery system.

Powder CoatingPowder is supplied to the spray gun from a feeder unit where the powder is diffused by compressed air into a fluid-like state. The fluidized powder is then siphon out by movement of high velocity air flowing through a venturi. It is propelled through the powder feed tubing to the spray gun.

The powder feeder provides a controlled flow of powder to the guns. Independent control of powder and air volume allows adjustable dilution ratios so a desired thickness coverage can be attained on a variety of product shapes. The powder feeder is capable of providing sufficient discharge pressure and velocity to feed the electrostatic gun 10 to 25 feet away.

Powder Coating

Powder leaves the spray gun in a form of a diffused cloud being propelled toward the work-piece. A high voltage, low amperage power unit supplies a charging electrode at the front of the spray gun. The charging electrode emits a field charge which is imparted to the powder particles. This causes them to seek out and attach themselves to the grounded work-piece.

The powder unit, or electrostatic voltage generator, has sufficient voltage to assure maximum wraparound. Voltage is variable up to 90 kV so that is may be; (1) reduced to combat Faraday “cages” encountered in spraying inside corners; (2) increased as necessary to provide wraparound, surface coverage, and efficient deposition of powder on convex surfaces and flat panels; and (3) adjusted for the powder being sprayed.
