RectorSeal®, Houston, a manufacturer of quality HVAC/R and plumbing tools and accessories and a wholly-owned subsidiary of CSW Industrials, Inc., is a master distributor of GulfCoat™ Circuit Shield™ conformal spray coatings.

Circuit Shield coatings

When properly applied, Circuit Shield coatings provide a clear, micro-thin acrylic coating that protects surfaces from the harmful effects of corrosion caused by environmental forces such as salty ocean air. Further, it helps to mitigate problems caused by pests such as geckos, ants, snakes, and mice.  

The easy-to-apply spray offers superior adhesion and can be applied on-site during installations. Formulated to support dielectric properties, Circuit Shield coatings offer enhanced UV resistance and excellent moisture resistance to coated surfaces.

Additional protection

Circuit Shield™ offers an additional level of protection to help extend the life of the equipment"

"When circuit boards fail due to corrosion like salty ocean air, it can be an expensive repair," said Caitlin Krc, Product Manager at RectorSeal.

"Additionally, outdoor pests often seek the warmth provided by a circuit board. That situation often causes a fault in the circuit board, the death of the pest, and expensive damage to the unit. Circuit Shield™ offers an additional level of protection to help extend the life of the equipment."

Reduce damage, Uniform thickness

Circuit Shield coatings are harmless to geckos and other pests but provide the needed barrier to reduce damage to expensive circuit boards. When properly applied, Circuit Shield spray coatings offer a uniform dry film thickness of 10-36 μm (0.4 -1.4 mils) and meet a 5B rating for crosshatch adhesion per ASTM D3359.

Corrosion durability shall be confirmed through testing to no less than 2,500 hours of salt spray resistance per DIN 53167 (ASTM B117) using aluminum test coupons. Dielectric Withstanding Voltage test shall pass at 1500 volts/mil thickness.

Protecting equipment

Circuit Shield coatings are used to protect elevator control panels, telephone communication boxes, outdoor timers

In addition to HVAC/R Printed Circuit Boards, Circuit Shield coatings can be used to protect elevator control panels, telephone communication boxes, outdoor timers and switches, traffic light and rail crossing control panes, automotive, heavy-duty, and off-highway equipment.

RectorSeal®, Houston, a manufacturer of quality HVAC/R tools and accessories, has been named the master distributor for GulfCoat™  Circuit Shield™ by Modine Louisville Inc., Louisville, Ky., and its subsidiaries which provide global coil coating services.  

Availability

The agreement allows RectorSeal to market GulfCoat™ Circuit Shield™, a contractor-applied HVAC/R conformal spray coating, throughout the U.S., Canada, and Australia. 

Founded in 1937, RectorSeal has centered around a simple growth mission: To provide innovative solutions to the professional trades. RectorSeal supports the heating and cooling, plumbing, electrical, and construction industries with a wide variety of products, services, and support programs.
