The latest update to the Cosmichrome base coat features a fantastic new feature. If someone accidentally touches the base coat you clean our spray chrome base coat with distilled water and a damp paper towel. Until now the part would dave to be sanded and sprayed with base coat again. It’s simple and easy.
If someone accidentally touches the base coat after it is dry you can clean off the fingerprints without any harm or damage to the final finish. All you have to do is wipe the fingerprints off with a soft paper towel that has been wet with distilled water. Then re-flame the base coat and proceed with plating as usual. This base coat is also extremely easy to apply and is very resistant to runs and drips. As usual the adhesion of the metal and top coat are exceptional.
This new feature solves one of the more demanding requirements of applying spray chrome coatings. Typically their base coats are very sensitive to accidental touches and other types of minor contamination. This would often lead to frustration when an curious coworker would decide to handle and inspect the parts being coated. Now one can just clean the fingerprints off rather than having to sand and reapply the base coat.
Additionally Cosmichrome base coat is still the only base coat that can’t be over dried. The dryer it is the better the adhesion of the metal and top coat. Other products are much more sensitive to over drying and loss of adhesion.
You can let our base coat dry all weekend or even all week and there will be no loss of metallic adhesion.
As always, Cosmichrome is the only spray chrome product guaranteed not to turn yellow. That is just one of the many reasons it is the spray chrome of General Motors, Andretti Autosport and West Coast Customs to name a few.
Spraying Chrome Instructions. How to Apply Cosmichrome Base Coat
V-BCL Base Coat 100 grams
V-BCL-CAT catalyst 40 grams
Reducer- None needed
Mix for 2 minutes before spraying.
Use a scale to measure the paints. Do not use ratios on mixing cups.
PLEASE NOTE THAT ALL PARTS MUST BE PREPAIRED PRIOR TO APPLIYING THE COSMICHROME BASE COAT. PARTS MUST BE SEALED AND WET SANDED WITH MIN 800 GRIT SAND PAPER. BCL BASECOAT WILL NOT COVER OR HIDE ROUGH IMPERFECTIONS ON THE SUBSTRATE.
Recommended primers: either urethane, epoxy or polyester. Primer must be catalyzed and must be completly dry before applying base coat. Spray chrome application requires completely dry base coat and primers.
Spray application
Adjust the spray gun as follows
35-40 PSI at the gun, (2 bars) lower pressures will cause the paint to dry slower so be careful
Wide open fan
Needle open 1 1/2 to 2 turns
Spray the substrate with one medium wet film in a cris cross pattern and let stand for 10 min.
Spray a wet second coat after 10 min have elapsed.
Once you are satisfied with you application allow 30 min to dry naturally before baking or allow to air dry at normal room temperatures and above.
BAKING BASE COAT
It is critical that the base coat is completely and properly dried! When in doubt such as on large or heavy parts or parts with heavy coats of base coat, dry the base coat longer. It is not possible to over dry the Cosmichrome base coat.
If you have applied a primer or other paint on a part first that paint must be completely cured before applying our base coat. If the base coat is wet or a primer beneath the base coat is wet then the final finish can discolor or appear foggy and intra-coating adhesion will be weak. Allow primed parts to bake for 1 hour to 1 hour 20 minutes at 140 F / 60 C
Longer dry times are fine if your part is large or has a lot of paint. The base coat can’t be over dried!
Higher temperatures can reduce baking time.
Allow parts to cool down to room temp before continuing the process.
NATURAL AIR DRY FOR BASE COAT
Once you have finished applying 2 or 3 coats, let the parts dry in a dust free environment (closed room) for 15– 24 hours minimum at room temp. Small parts dry faster. Large parts take longer to dry properly. When in doubt allow the base coat to dry longer. Our Base coat can’t be over dried so there is nothing to worry about drying parts longer. Even if you bake the part and want to wait until the next day or over the weekend to plate there will still be excellent adhesion. We have accidentally baked parts at 320ºF for 1 hour and the adhesion was still excellent. The base coat discolored and turned brown and it did not damage the coating.
Please note if you have sprayed more then 2 coats of base coat allow more dry time, 24 hours minimum. Minimum!
