Powder Coating Paint System

Gilbert Electrical Systems and Products is proud to announce the introduction for our new state of the art POWDER COATING paint system utilizing Alesta^® Powder coatings by DuPont. This powder Coating is now offered as an alternative to our conventional spray painting at no additional cost

This is a superior system to other standard paint systems and has excellent hardness, flexibility, exterior durability, corrosion resistance, and chemical /solvent resistance. Our factory employs a five stage pretreatment process that cleans, treats and seals the material to be coated, ensuring a quality, corrosion resistant finish.  This process first thoroughly cleans the steel and then treats it with an Iron Phosphate conversion coating that serves as a rust inhibitor and bonding agent for the Powder Coating.  The final step in this process enhances the corrosion resistance of the painted part as well as increasing the adhesion properties of the topcoat. All five steps work together to ensure a superior finish.

The standard colors available are Ansi 70 Gray, Ansi 61 Gray, Munsell Green, Evergreen, Sky White, and Safety Yellow.  Other colors are available at additional cost on request.  The interior and exterior are usually painted the same color, however two color paint schemes or different interior color schemes may be accommodated by referring to sales for pricing.

New Polypropylene Paint Booth  - 32’ long x 15’ wide x 15’ high

The paint booth system incorporates two (2) Nordson Sure Coat II Manual Electrostatic spray gun systems with 50 lb. powder feed hoppers and a dual Nordson Versa-Coat 7200 powder collection system.  The system operates with an automatic feedback current control with three preset coating modes to assure a consistent, uniform powder application.

The new oven operates with a Maxon 2.5 million BTU burner, and a Honeywell / Allen Bradley PLC control system to assure accurate dependable temperature control.  The end result is a uniform highly durable finish.

TGIC-Polyester Technical Summary

General Specifications

TGIC-polyester powders where introduced in the late 70’s and were designed for decorative and protective and applications where exterior durability is a requirement.   These powders spread evenly, informally and have excellent adhesion to steel enclosures.

Adhesion (ASTM D-3359, Method B)

Using pressure sensitive tape, no coating was lifted or removed between 1/8” crosshatch scribes.  (Rating = 5B)

Impact Resistance (Modified ASTM D-2794)

Using a falling weight impact ester, the film surface withstands up to 160 inch lbs. of direct and reverse impact.

Flexibility, Mandrel (Modified ASTM D-522)

The film surface withstands an 180⁰ bend over a 1/8” diameter with no loss of adhesion or surface cracking.

Abrasion Resistance (Modified ASTM D-4060)

Coating weight loss after 1,000 cycles of Taber abraders equipped with CS-10 wheels loaded to 1 kg per wheel is approximately 40-60 mg.

Corrosion and Chemical Performance Properties

Salt spray Resistance (ASTM B-117)

Scribed Bonderite 1000 steel panels in a 5% salt fog at 95⁰ F and 100% relative humidity, exhibit no undercutting of the film after 500 hours of exposure.  No rusting or blistering occurred on panel face away from scribes. After 1,000 hours there is less than 1/16” undercutting.

Alesta^® powders is UL recognized for steel enclosures for outdoor use.
