43nd Turbomachinery and 30th Pump Symposia September 23-25 in the George R Brown Convention Center, Houston TX booth 2017. Southwest Impreglon will be highlighting several coating technologies for turbines, reciprocating equipment, and pumps. In particular, Impreglon 809 , Impreglon 807 Blue, Xylan®, Impreglon 445 and polyurethane coatings will be featured.
Southwest Impreglon applies proprietary Impreglon 809 aluminum-ceramic thin film coatings aluminum to provide long lasting corrosion resistance to metals operating in harsh environments up to 1200oF. The coating system cuts costs by reducing downtime, extending service life, and slowing part wear. This coating is especially good for extending the service life and operating efficiency of turbine blades and vanes. Southwest Impreglon also applies Praxair SermaGard® and Alseal aluminum-ceramic coatings.
Impreglon 807 Blue is a multi-layer systems consisting of an aluminum rich base coat, epoxy/phenolic mid-coats, and fluoropolymer top coats. The coating provides a hard, abrasion resistant, corrosion, and chemical resistant, non-stick film that offers excellent performance up to 400oF.
Xylan® are fluoropolymer-based coatings that are formulated to prevent galling, provide lubricity, improve corrosion resistance, as well providing different colors. Southwest Impreglon applies numerous Xylan® coating as dry-film lubricant; however they also have many desirable secondary properties. Xylan coatings can work under heavy loads, up to 500oF, in corrosive chemical environments, and combinations thereof.
Impreglon 445 is an epoxy coating designed to corrosive environments in the oil and gas industry. Typical applications include sucker rods, valves, pumps, and brine water treatment and handling equipment.
Polyurethane coating are exceptional for abrasion resistance and impact resistance. Polyurethane are often coated into pump internals to reduce the damage due to cavitation and abrasion due to pumping slurries. Polyurethanes coatings provide a seamless alternative to rubber linings often with better service life.
Southwest Impreglon applies functional coatings for oil and gas, power generation, and chemical industries. We apply over 300 coating systems including Xylan, Teflon, Sermagard, TSA, and Halar. Company was founded in 1975, operates on 12 acres, and processes parts within 80,000 square feet of manufacturing space in Humble TX.

SOUTHWEST IMPREGLON EXPANDS TSA COATING CAPABILITIES
Southwest Impreglon, Inc. has increased it’s production capacities for Thermal Spray Aluminum (TSA) coatings. These sacrificial coatings provide much better corrosion resistance than paints and galvanizing. The advantages of TSA include: long term durability and protection even with a porous or breached coating, and the ability to quickly coat large parts.
Southwest Impreglon uses the “twin wire arc” method which sprays atomized molten aluminum onto a metal substrate to produce coatings which are typically 0.006” to 0.010” thick. This method offers exceptional coating bond strength.
In addition to sub-sea and marine applications, TSA is often used for corrosion protection in petrochemical plants as a solution to “corrosion under insulation” (CUI) attack. These aluminum coatings offer protection for aggressive environments containing oxygen and sulfur. These corrosive effects are enhanced for processes operating at high temperatures, leading to a faster degradation of mechanical components. TSA coatings can be used up to 1000oF.
Applications in Oil & Gas and Petrochemical Industries are:
Choke and kill lines

Southwest Impreglon Expands its line of VICTREX PEEK Coatings
Southwest Impreglon has expanded its line of VICTREX PEEK-based coating systems to include thin-film dispersion formulations. Previously, VICTREX PEEK, a semi-crystalline thermoplastic and member of the polyaryletherketone (PAEK) family, was only available for application as a thick film layer of (15-25) mils.
VICTREX PEEK-based coatings are durable, impact resistant and pin-hole free with outstanding chemical resistance with a continuous operating temperature of (500F(260C), UL746). The new dispersion formulations now allow for VICTREX PEEK polymer to be applied in thinner coating layers of (1.0-1.5) mils thick, while lending themselves for application on more complex metal parts with closer dimensional tolerance.
When asked how these coatings compare to fluoropolymer coatings of similar film thickness, George Butler, principal and chemist for Impreglon said “All end-use applications are different, but VICTREX PEEK polymer’s excellent fatigue resistance and general mechanical properties have been shown to outperform fluoropolymers, while the chemical resistance is vastly superior to metal components for such applications. And since we are able to formulate VICTREX PEEK with other polymers and additives, we can further improve or incorporate certain desired characteristics for our customer’s end-use applications. We have at least seven specially formulated blends that we are currently applying and the number continues to grow as we find new applications and develop new formulations to meet our customer’s needs.”
VICTREX PEEK-based coating systems currently being applied by Southwest Impreglon are shown in the chart above.

Southwest Impreglon Expansion Completed!
Southwest Impreglon completed its expansion project in late April 2003. The new construction increased the production area by an additional 12,000 sq. ft. and increased large part handling capability in the process.
Pictured clockwise from top left are the new coating spray booth (16’wide x 16’ tall x 45’ long), the new coating furnace (12’ wide x 12’ tall x 42’ long) with 850 degree F heating capability, the new blast room (15’ wide x 14’ tall x 45’ long) and the new 10-ton overhead crane system.
According to George Butler, President & Co-Principal, “The originall coating facility was always built with expansion in mind to better serve the company’s ever expanding customer base as well as its continual addition of new coating processes. Now that the expansion has been completed, we invite our customers to challenge us with some of their larger parts requiring coatings application.”
Southwest Impreglon Achieves ISO 9001:2000
As of August 12, 2003, Southwest Impreglon became ISO 9001:2000 Certified. This has now replaced the obsolete ISO 9002 standard to which the company had been previously been certified.
In speaking with Terry Bourdon-Quality Assurance Manager for Southwest Impreglon, he said meeting the criteria for the new standards was tough, but well worth the time it took to get there. Achieving certification required hours of close review and usually, revisions in the company’s quality manual, procedures, work instructions and other forms.
Asked why ISO certification was so important, he responded that “Certification was important to us because it is recognized worldwide as an accepted standard of quality. When companies can accurately document their quality systems, they can compare their systems against a recognized quality standard and improve what they offer to their customers. Also, because ISO certification is an understood standard, companies can use it to gauge and select the vendors or sub contractors they work with. Having successfully gone through the ISO review process and achieved ISO 9001:2000 certification, customers can trust that Southwest Impreglon has already asked the tough questions about its own quality systems”
Southwest Impreglon Now Offers Peek Powder Coatings
Southwest Impreglon has begun offering the application of Peek Polymer Coatings. Peek polymer is a semi-crystalline thermoplastic which is widely regarded as having the best combination of properties for harsh environments. The product is formulated to produce durable, impact resistant pin-hole free coatings from 15-25 mils thickness.
The coating can be machined for those applications requiring closer tolerances. Peek polymers coatings possess the following properties:
- Abrasion Resistance
- Wear Resistance
- Heat Resistance
- Chemical Inertness
- Hydrolysis Resistance
- Dielectric Properties
- FDA Conformance
