Handling
Quantity to apply depends on substrate porosity: from 2 to 3 g dry/sqm (on coated paper we suggest 2 g dry/sqm). Methods: Meyer bar, Reverse Roll, Roto gravure, Air knife.
It can be either thickened (acrylic thickeners) or diluted.
It is advised to heat the product for a few seconds at 150°C in order to achieve the highest properties of releasing. However results are good (but inferior) also at lower temperatures. Ageing properties are excellent.
Packing
RELEASE W 20 S is supplied in 200 l plastic drums or 1000 l tanks.
Storing
Keep material at temperatures between +5°C and +40°C, avoid direct sunlight
When stored for over one month it is necessary to stir product for 10 - 15 minutes before use.
Shelf life is 3 months.
Notes
Product can be supplied in two higher TS versions:
RELEASE W30 S (30%)
RELEASE W40 S (40%)
Viscosity can be increased, according to the coating system used.
