Innovative Coating Solutions

Houston Powder Coaters (HPC) warrants that the process of pretreatment, powder application, and cure of all coated parts meet or exceed the industry standards set forth by the powder manufacturers.

This warranty excludes any damage to the item(s) which occurs during shipment, due to failures caused by products not supplied by HPC, and/or failures resulting from misuse, abuse, accident, neglect, mishandling, misapplication, alteration or modification of the item(s) which in turn, causes premature corrosion or coating failure.

Due to environment, consumer usage, metal construction, and fabrication variances, all of which are outside the control and responsibility of HPC, this warranty is limited. Upon notification of a coating failure, HPC reserves the right to inspect and determine the cause of the failure as well as the action, if any, that will be taken to rectify the problem. Under this warranty, HPC, in its analysis of the failure in question, may conduct several tests on the part(s) in question, inclusive of destructive testing of the powder coating.

Upon notice and determination of a valid claim, HPC will recoat the part(s) at HPC’s own expense. HPC is not liable for the cost of disassembly, removal, reinstallation, or transportation of the affected part(s). This warranty does not cover the repair of the item(s) by any other service provider and is limited to the original purchaser.

If, however, upon analysis that the damaged powder coating was not due to a failure in pretreatment, powder application, or cure, the cost of recoating the piece(s) will fall onto the customer.

The following acts and/or omissions will void this warranty: 1) Physical damage due to transportation, assembly, or installation, 2) Contact with industrial chemical agents, salt water, or other corrosive agents, 3) Alteration of the coating by the owner or agents of the owner, 4) Physical damage due to environmental hazards and act of God.

HPC is not responsible for the rust, rust seepage, oxidation, or coating failure of the following:

• Weldments and frames that have overlapping metals that allow moisture to enter and remain trapped. This includes, but is not limited to, seams that are not seal-welded.
• Interior sides, compartments, or spaces of the weldment where powder coating cannot penetrate.
• Improper/poor design, construction, or assembly. This may include, but not limited to, welding flaws (inclusive of splatter and pinholes), over-torqued screws, impact assembly, or improper handling.
• Non-coated / masked part(s) of weldments.
• Coated part(s) that are nicked, cut, scratched, or have any other damage that breaks the seal of the powder coating. This may also include normal wear and tear.

Since the powder coating process involves curing (baking) components, HPC will not warrant any damage to any piece(s) that cannot withstand the oven temperature of 400°F. This includes, but is not limited to, seals, bushings, electrical wiring, plastics, rubber, or internal components. HPC is also not responsible for the damage to items removed per customer request. Furthermore, any sealed tube, tank, or enclosure must have a weep hole to allow for gases to escape during the curing process. As thin-gauged metal or old/reused metal pieces may warp in the oven, HPC does not take responsibility for any damage the oven may produce.

Environmentally Friendly

Plain and simple, powder coating is the most environmentally responsible metal finishing process.

Since no solvents are used in its application, negligible amounts of volatile organic compounds (VOCs) are released into the atmosphere.  Furthermore, electrostatically sprayed processes, like the ones Houston Powder Coaters employs, are now specified by the EPA as a Best Available Control Technology (BACT) to help reduce air pollution.

While powder coatings have many process and performance advantages over traditional wet coating systems, the Clean Air Act of 1970 was instrumental in placing powder coating at the forefront of eco-friendly industrial processes.  Unlike some finishes, powder coating contains no heavy metals or harmful carcinogens and produces less hazardous waste than conventional liquid coatings.

As discussed in the “Frequently Asked Questions” section of the website, thicker coatings can be applied in single pass powder systems without the appearance of runs and sags that would be seen in wet coating systems.  The ecologically-friendly process is also economically-friendly due to the faster processing speeds.  And with a fusion-bonded, cross-linked, hardened shell, powder coating produces a superior finish that is more abrasion, corrosion, and chemical resistant than wet paint applications.

Houston Powder Coaters is committed to keeping Houston clean by providing environmentally responsible protective coatings.  If you have additional questions, or need supplemental data sheets, please contact This email address is being protected from spambots.

Health & Safety Are Paramount

Beyond the environment, Houston Powder Coaters is also committed to providing a safe & healthy work environment for its employees, neighbors, and others affected by its business activities.  Health & Safety is an integral part of its business and is as much a part of its culture as any other business objective.  All employees share in the responsibility to continuously improve the health, safety, and environmental awareness of the company by:

• Maintaining a clean and safe work environment
• Conducting regular workplace inspections
• Stopping any process at any time if an unsafe situation arises
• Reporting unsafe acts, practices, and conditions
• Assessing risks and striving to eliminate all work place incidents
• Regularly servicing all tools and equipment
• Wearing protective gear – coaters and blasters wear full body suits and head pieces with independent air circulation systems
• Integrating process safety, and worker health & safety, into all business decision-making practices.

All employees of Houston Powder Coaters are expected to conduct their daily tasks in a manner consistent with the objectives and regulations set forth by the company.  Health and Safety are the responsibilities that must be shared equally and without exception by each individual within HPC.  It is clear that no activity is so important or urgent that safety can be compromised.

“Safety First – Safety Last”

Powder Coating

Houston Powder Coaters warrants that the process of pretreatment, powder application, and cure of all coated parts meet or exceed the industry standards set forth by the powder manufacturers.  Depending upon the criteria put forth by the individual powder coating supplier, HPC will preheat pieces which results in better powder adhesion and increased flow properties.  Certain aluminum pieces and galvanized parts will also receive preheating to reduce outgassing during the coating process.

Although the typical coverage of powder is 3-5 mils per coat (6-10 mils for a standard double coat), Houston Powder Coaters can apply thinner and thicker levels depending upon customer’s request.

Curing times vary due to the thickness of the metal, the type of metal, and the coating system that was applied.  In oven temperatures that exceed 425 degrees, the typical curing time ranges from 20 minutes to 2 hours.

Present day powder formulations allow for certain tolerances/graces above and below the ideal curing conditions.  This “bake window” allows Houston Powder Coaters to properly cure the spec’d powder within a broad temperature and bake time range.  In fact, these bake windows are the reasons why HPC can cure different size pieces with different colors in the same oven at the same time (at the same temperature).

Finally, when pieces exit the oven, final inspection tests are performed to ensure film thickness, proper curing, and even-flow.  These inspections are completed in one of two brightly-lit indoor quality-assurance areas.  HPC’s quality inspectors are trained to look for issues that will lead to coating failure.  If any problems are found, rejected pieces are sent to be reprocessed all over again.

Certificates of Compliance are available, but need to be discussed and agreed to at the onset of any job.
