SEALER is a fast drying coating that penetrates porous materials such as cloth, leather, plaster of paris, concrete etc. rendering it non-porous.
The concentrate can be used as is, or thinned with an equal amount of water. The part is then totally immersed in the solution for 15-30 minutes, then allowed to drip dry. A second application several hours later renders the surface completely smooth and non-porous.
To make the part conductive the part is then sprayed with SilvaSpray. Finally, the part can be plated with Bright Acid Copper, Nickel or Copy Chrome.
