Gessner impregnates its special technical papers using the Kiss Coat process based on methanol or, in a size press, based on water. Impregnating with phenolic, epoxy, acrylic resins or latex gives high strength, dimensional stability and improves resistance to solvents, chemicals and high temperatures.
Special additives, depending on need, can be added to give further functionality. For example, hydrophobic, hydrophilic or oleophobic properties, flame retardancy, various colors, UV stability, bactericides, fungicides, etc, can all be built-in.
Using two further coating devices [air knives], we can add still further functionality.
Decreasing space under the hood and the increasing volumes of air needed by engines today mean that highly specialized filter media with high dust holding capacity (DHC) are required!
