Handling
The quantity to apply depends on the substrate porosity, normally ranging from 1 to 3 dry/sqm.
Coating methods: Mayer bar, Reverse Roll, Roto gravure, Air knife.
It can be either thickened (acrylic thickeners) or diluted (water).
We recommend to heat the product for a few seconds at 150°C in the dryning phase, in order to achieve the highest release properties of releasing (achieved by means of an underlying self-curing process),
Ageing properties are excellent.
