Siliporite NK 20 AP
Siliporite NK 20 AP
SILIPORITE® NK20AP is a synthetic zeolite type A of crystalline structure in Calcium Sodium Aluminosilicate powder form, having a low density and an effective pore opening of approximately 5 angstroms (5Å) efficient for water adsorption and for low molecular
weight organic molecules such as some VOCs.
Applications include:
- non-foam polyurethane systems such as paints, coating, sealant, adhesives and elastomers, 2K & 1K polyurethane systems
- castor oil molecular sieves paste formulations, thanks to the small crystal size of Siliporite® NK20AP
