The Cosmichrome intermediate coat is a series of water borne steps that result in a mirror like coating on properly prepared surfaces. The Cosmichrome primer must be used on all other surfaces. The intermediate coat must be protected by the Cosmichrome Topcoat.
Wear respirator and
personal protective gear to eliminate chemical exposure risks.
Use a catch basin to collect waste water runoff and treat according to
directions.
Items to be sprayed must have Cosmichrome Primer.
• Activator
solution is sprayed on the product (using a single nozzle spray gun)
• The product is then rinsed with purified (distilled) water
• Immediately after the rinse, the product is sprayed with the Cosmichrome
intermediate coat (using the two nozzle spray gun)
• Always work yourself from the bottom up until you achieve a uniform
reflective appearance
• The metalized object, is rinsed again with purified (distilled)
water and blown with clean compressed air to remove all access water
• Object is ready to topcoat as soon as dry
Storage: Store at ambient conditions
Safety Precautions:
Please refer to the Material Safety Data Sheet
Method of Metallizing:
The dry, base coated pieces are now ready for the metallizing step. Once the pieces have been base coated they should not be handled with bare hands, as the Cosmichrome intermediate coat will reproduce every fingerprint.
Step 1 – Activator:
Activator solution is sprayed through the single nozzle spray gun. The piece should be thoroughly covered with Activator and then rinsed with de-ionized/Distilled water.
The Activator solution must wet the surface completely. If there are any water breaks and/or separations, it either indicates the presence of contamination of the basecoat, incomplete basecoat, or even evidence of incomplete priming. A second spray and rinse can be tried.
Complete sheeting action of the Activator is a must!
Step 2 – Cosmichrome Intermediate Coat (Catalytic Plating):
Immediately after the piece has been rinsed, and while it is still wet, spray the two component Cosmichrome solution with the 2 nozzle spray gun.
The two solutions should be coming out of the gun at close to equal volumes. The gun can be calibrated with the knobs in the back of each nozzle. The nozzles should be set so that the streams merge at least four inches from the tips.
The gun should be positioned so that piece to be metalized is only a few inches (3 to 5) beyond the merged stream. Start spraying from the bottom of piece and work up, holding the trigger while facing the piece at a 90-degree angle.
To insure a uniform finish, spray using a smooth, lateral movement in one direction only. Do not use a back and forth motion! The Cosmichrome is being chemically deposited unlike lacquer or paint, which is built up in layers. It is therefore impossible to deposit more on an area that has already been sprayed. A back and forth motion will not produce a better finish, and in fact, too much re-spraying can result in a burnt appearance.
The metalized pieces are then immediately rinsed again with de-ionized/distilled water and blown with clean air to maximize the brilliance.
After removing all
traces of water, the top coating should be then applied.
