The antique finish processes offered by Birchwood Technologies are designed to produce a high quality, hand-crafted antique finish that enhances the appearance of the decorative hardware, lighting fixtures and architectural elements.
Birchwood Technologies antique finishes provide a range of colors and tones on most metal surfaces including steel, brass, bronze, copper, pewter, aluminum, silver, nickel and zinc. Color ranges can include black, golden to chocolate browns and other red or green color variations, depending on the application. All the processes are simple to use and typically require: surface cleaning; water rinsing; olorization/oxidizing; water rinsing and highlighting and/or sealing. The processing steps can be customized to produce unique color tones.
Birchwood says its processes are operator friendly, using room temperature solutions that produce no fumes. Consequently, they can be used in either manual short run or high volume production process lines. The coloring operation can be set up as a stand-alone line or integrated into an existing plating line. The coloring solutions can be easily tested and replenished to maintain optimum concentration and produce consistent results from batch to batch.
The Birchwood Technologies antiquing processes can be set up to produce near zero discharge of rinse waters to the drain using their ion exchange system. This accessory simplifies operation and eliminates environmental liability.
