Plastic, being a non-conductor, has to be made conductive for a plate to adhere to its surface. SilvaSpray or the new water based copper conductive medium (CCM), (CCM requires an immersion in the Caswell Immerse Tin Solution tank), is designed to bond tenaciously to most plastics. It will also cover most other nonconductive materials, giving good adhesion and provide the metalisation required. Connect wires to the part to be plated, in order to conduct electricity to the part for plating. It is important that you do this PRIOR to coating, to enable the coating to make contact with the wire. Apply by spray or brush, an even coat of SILVASPRAY Silver or Copper Conductive Paint Attach a copper wire to the item, to conduct the electric current. Shake the canister vigorously for at least two minutes. Pour the liquid into the spray gun (air brush etc) and check for sediment in the original container and if present, remix the solution until all copper sediment is suspended in the solution. Spray a light mist coat onto the part, and allow to dry for at least 5 minutes (@ 68 f min). Spray a second heavier coat, at about 12" from the object, ensuring you spray up to and over the copper plating wire. Allow to dry for at least 15 minutes. Plate the part for approx 30 minutes in Bright Acid Copper - do not use Flash Copper. Once plated with copper you may polish lightly, then nickel and/or gold plate
BRONZING BABY SHOES BABY SHOES: Replace laces if worn. Wash the shoe and laces separately in detergent and allow to dry. Tie the laces, and allow them to fall naturally Glue them into position using a hot melt glue gun. Glue the tongue into position. Cut off any frayed stitching etc. To aid in sinking the shoe, you may pour some Plaster-of-Paris into the toe. This will also help the shoe keep its shape. Allow to thoroughly dry – two days or more if necessary. Affix plating wires to the shoe. You could put a couple of wood screws in the sole and heel of the shoe and also use the shoelace holes. The more wires the better conductivity you'll get. Immerse the shoe into the mixed Caswell Sealer for 30 minutes, stirring occasionally to remove any entrapped air bubbles in the toe area. One part Water based Caswell Sealer is mixed with 1 part of water before use. Make a shoe rack by hammering several 4" nails into a small plank of wood. Invert the shoe over the nail and allow it to drain and thoroughly dry for about 4-8 hours.
“Caswelleurope Acrylic Sealer is used for fabric, leather, plaster, wood paper and other porous materials that require metalisation” Connect wires to the part to be plated, in order to conduct electricity to the part for plating. It is important that you do this PRIOR to coating, to enable the coating to make contact with the wire. Although SilvaSpray is formulated in mild solvents, the user must test the compatibility on the actual moulded parts to determine its suitability for any specific application. The following application parameters should be followed for optimum properties: Material should be stirred thoroughly before use. Material should be incorporated into a recirculating system where possible. Pressure in the system should be adjusted to produce sufficient flow rates to ensure suspension of the metal. The gun should be set as follows: Completely shut off needle to the gun. Slowly open needle to achieve a minimum wet film. Adjust fan for size of part. Readjust needle setting to ensure minimum wet coat. By following the above procedures, a number of benefits will be achieved. The optimum minimum film thickness will result in minimum cost per part. The above techniques will produce a very smooth and bright appearance. Maximum conductivity will also be achieved. Be aware that Silvaspray™ dries rapidly. Apply by spray or brush, an even coat of SILVASPRAY Silver Conductive Paint as follows: As previously mentioned attach a copper wire to the item, to conduct the electric current from the tank bar. Shake the canister vigorously for at least two minutes. Pour the SILVASPRAY liquid into the spray gun (air brush etc) and check for sediment in the original container and if present, remix the solution until all silversediment is suspended in the solution. You may add up to 5% ethyl alcohol to aid spraying with an airbrush but this has not usually been necessary as the consistency of the silver medium is ideal for most air brush units. Spray a light mist coat onto the part, and allow to dry for at least 5 minutes (@ 68 f min). Spray a second heavier coat, at about 12" from the object, ensuring you spray up to and over the copper plating wire. Allow to dry for at least 15 minutes.
Suspend the shoe from the Copper tank bar, Do not use Alkaline or Flash Copper for the process, which should already be wired to the power unit and should be “live”, and immerse in the copper plating tank. The shoe should immediately start plating. The average baby shoes will measure approximately 25-30 square inches so should be plated at the rate of (1amp per 20 sq ") 2-3 amps Plate for approximately 1 hour. Remove and inspect. Sand/emery any rough spots. Continue plating for about 2-3 hours or until you think the plate is thick enough, checking periodically for any rough spots, which should be sanded smooth. Smooth cloths and leather will have different appearances. Rinse the part off, or polish lightly, then nickel and/or gold/ silver plate. If plating with nickel, gold or silver, then the part needs to be
polished to a high shine, to give best effect. If plating with Bronze using the Bronze plating kit refer to the instructions in this manual for the process to be followed. See the Plating Manual, ANTIQUE AND BLACKENING TECHNIQUES, for a choice of antiquing finishes, Brush the shoe with steel wool or a soft buffing wheel and compound to remove the antiquing oxides and expose the copper on the high spots. Finally, if required dip into Caswell Sealer and rack to dry.
