The “varnishing”, the application of the Gel-Coat, is the first step in the production. Thereby this step the filter tanks obtain a visual smooth surface on the outside.
Given that Gel-Coat bases upon the same substructure as the used resin, during the application of the first lamination the two bond together.
Basically, it is possible to paint the tanks in any colour. To ensure a uniform colour, we are referring to the colour range of RAL colours.
Since special colours are ordered separately, a special paint finish is only possible above a certain ordering quantity.
