Bright Dip Coatings
Gleco offers bright dip chemical brightening coatings for companies seeking to remove surface scale and oxidation and produce an extremely high luster on brass, bronze, or copper parts or products (the degree of brightness depends on the surface finish and alloy type; the harder tempered the alloy is, the brighter the end product will be). This process uses an acid-based chromate conversion coating to clean impurities from the parts’ surface and protect and extend the life cycle of the base material.
While it doesn’t remove surface scratches or marks, bright dipping is ideal for products with unusual shapes, sizes, contours, and porous surface areas. Pretreatments for bright dipping include, buffing, brushing, polishing, sand blasting, glass bead blasting, masking, and tumble deburring.
The Bright Dip Process
The bright dip is applied by first cleaning the parts to remove oil, dirt, and contaminants, then dipping them into the acid-based chromate conversion coating. Bright dipping process times are determined by the degree of scale, ranging from as little as a few seconds to 5 minutes.
Benefits
Bright Dip Coating is used to perform a number of purposes, including:
- Removing heavy scales and oxides from metal surfaces
- Removing material to get parts into tolerance
- Removing burrs and other surface defects in the base metal
- Providing a wide range of finish appearances
As a coating, this process offers several important benefits:
- Improves Aesthetic Finish
- Tarnish Resistant
- Corrosion Resistant
- Adds Longevity
Applications
Bright Dip Coating is used by the Aerospace, Electronics, Medical, Construction, and Automotive industries to finish:
- Hydraulic fittings
- Electronic components
- Medical hardware
- Machine parts
- Appliances
- Automotive components
- Architectural trim
- Light reflectors
- Window frames
