Handling
Quantity to apply: it depends upon substrate porosity: usually from 1 to 3 g dry/sqm.
Methods: Mayer bar, Reverse Roll, Roto gravure, Air knife.
It can be either thickened (acrylic thickeners) or diluted (water).
It is advised to heat the product for a few seconds at 150°C in order to achieve the highest release properties (a self-curing process takes place).
Ageing properties are excellent.
Packaging
The product is supplied in iron drums (200 kg); IBC containers (1060 kg).
Storing
Keep material at temperatures between +5°C and +40°C, avoid direct sunlight and freezing conditions.
Before use, the product must be stirred slowly for 10 - 15 minutes.
The material is subject to stratification and, after a prolonged storage, skin/crusts can appear on the surface. In this case, it is sufficient to remove skins and crusts and stir well.
Use within 9 months from production date (unopened and in the original packaging).
