SpectraShield® Powder Coated Finish
For aesthetics, for superior finish life and for cost-effectiveness, design professionals and building management are turning more frequently to the environmentally friendly powder coat finishing process. Cornell stocks 32 powder coating colors with more than 200 colors available.

In-House State-Of-The-Art SpectraShield® Production Line
Cornell controls every step of the SpectraShield process. Their production line is state-of-the-art, with an automated continuous conveyor, metal cleaning and preparation, automatic powder guns, and a curing oven. The line is tailored to Cornell products, enhancing quality and field performance and shortening and assuring manufacturing lead times.

SpectraShield® Outperforms Field-Applied Finishes
The SpectraShield process applies a baked-on organic polymer over a conversion coating. All SpectraShield components are prepped, powder coated and cured with an electrostatic application that assures uniform, total coverage and a smooth finish that is tough and durable. SpectraShield outperforms field applied coatings in color retention, corrosion resistance, chemical resistance, UV stability, and abrasion resistance. Color formulations are electronically controlled. Additional or replacement components match previous shipments.

SpectraShield® Controls Costs
Factory-applied powder coating is cost effective and competitive with field-applied solvent-based coatings. Proper surface preparation in the field is difficult and costly. Surface preparation by a factory powder coating process produces a smoother, longer-lasting finish at controlled costs.

SpectraShield® is Environmentally Friendly
Powder contains no solvents and so emits no polluting volatile organic compounds into the atmosphere. Oversprayed powder is collected and recycled.

SpectraShield® is Standard Finish On Many Cornell Components
Cornell provides powder coated guides, bottom bars and endplate brackets as the standard finish so that your jobs look better, longer. Unless specified otherwise, rolling door components will be finished according to Cornell's standard manufacturing procedure.

SpectraShield® Specifications (2.03 Finishes)
A. Steel slats, hood and endplate brackets, bottom bar and guides to be coated using a fusion bonded thermosetting polyester powder coating applied to a minimum of 2-1/2 mils cured film thickness. Color as selected by architect/owner. Pencil hardness to be rated at H or better per ASTM-D-3363.

While powder coated finishes offer exceptional toughness and impact resistance plus superior resistance to abrasion and chipping (due to the use of higher molecular weight resin systems), all coiling doors, high cycling doors in particular, are subject to wear. Durability of the finish varies with the door's use, pattern and size. Finish is not subject to warranty. Matching touch-up paint is supplied from the factory.
