The following is a list of the basic equipment and products needed to successfully apply Tech Line™ Coatings    



Pre-clean all parts. Remove all oil, grease, dirt, moisture or other contaminates.

Sandblast utilizing 120 grit aluminum oxide or similar hard sharp material such as silica sand or garnet @35 PSI in a suction type cabinet.  You may use 100 grit on exhaust ports.

Remove all blasting residue or oil from hands if handling the parts after blasting/etching. It is best to handle with hooks or clean cotton gloves.

Apply the coating. For best results use a gravity feed (top feed) detail touch up type gun with a nozzle size of less than 1MM. Either standard of HVLP, though an airbrush works quite well. Apply coatings at 30 to 35 PSI for solvent born coatings or 50 to 60 PSI for water born coatings. Film thickness will vary from .0003” to 0015”. All coatings should go on with a wet appearance. Multiple coats are not necessary and are wasteful. Coating should be applied in a spray booth with proper ventilation. Use appropriate chemical respirators when spraying solvent born coatings. When spraying water born coatings it is best to wear a respirator as well to avoid breathing fine particulate matter and mists as some contain a small amount of acid. Always consulate the MSDS.

Inspect parts for complete coverage and for runs or other indications of improper coverage.

For most coatings simply allow 5 to 15 minutes at room temperature for drying. All water born coatings may need a little heat to accelerate water evaporation.

For coatings requiring oven baking, bake in any oven capable of holding the parts and achieving the bake temperature specified in the instructions. Bake time is 1 hour, the time starts when the part(s) reach the bake temperature.

After parts cool, Inspect parts for complete coverage and for runs or other indications of improper coverage.

All air pressures given by TECH LINE for sandblasting are based on the use of a suction type sandblast cabinet. Pressure pots while excellent for many applications must be pressurized at much lower settings than are given in our instructions. If using a pressure pot you will need to experiment to determine the proper working pressure. In addition a pressure pot will need an internal agitator to keep the solid in suspension.

The solvents recommended for degreasing are; acetone, M.E.K., lacquer thinner or other non-petroleum based materials. You must use a solvent that leaves no residue. In many instances if you handle the parts with hooks or clean cotton gloves it will not be necessary to degrease after blasting. If the part has been handled be sure that the solvent is completely evaporated before handling.
