FOR HARD-ANODIZING

Sanford electrolytic additive - "Sanfran" - the proprietary additive is integral part of our internationally patented processes for the hardcoating of aluminum and important for energy saving for any hard-anodizing process. The additive, when added to an electrolyte solution (approx. 5% of volume) reduces the chance of burning aluminum alloys. There are no hazardous, toxic or flammable materials used in the manufacture of this additive.
The Classic Sanford Process™ had its beginning in California and was the invention of Dr. Paul Sanford. Hardcoating of aluminum by customary processes always presented difficulties when alloys of high impurity were processed. This was particularly true when alloys containing significant amounts of copper - 3.5% to 4.0% - were processed. Catastrophic dissolution, called "burning" led processors to avoid these alloys, or at a minimum, imposed limitations on the hardcoat thickness to less than 2 mils (50 microns). Even then extreme care was necessary and results were uncertain. Dr. Sanford, in collaboration with John Franklin, invented an additive called "Sanfran" which, in combination with a modified electrolyte, not only eliminated "burning" on high copper and other difficult alloys of aluminum and improved the quality of the hardcoat film, but also produced noticeable energy savings. Additionally, with the new electrolyte it was possible to form thicker coatings. The process utilized pure DC current at voltages up to 100 volts with a current density up to 40 amperes per square foot. This process is known as the Classic Sanford Process™. It was used extensively to process components for the aircraft industry.

"Antifoam" - an additive for reducing the foam phenomena during the hardcoating process.

Sanford Hardlube - a combination of "Teflon" and Sanford Hardcoat for better release... lower friction on hard coated aluminum.

 
 

SANFORD MASKING MATERIALS

Sanmask -"a" - a thin masking solution which is easily applied to small areas, as well as large areas, and especially for intricate applications. It is non-peelable; removable by solvent.

Sanmask - "b" - viscous, fast drying, easily peelable for removal, especially good for masking aluminum and steel.
