-ability of P olyisocyanates in W ater B
hydrophobic polyisocyanate mixed by hand
hydrophobic: high shear forces
or
low viscous, hydrophilic polyisocyanate -mixing by hand possible
Hydrophylic P olyisocyanates Standard type: easily dispersible PET modified HDI-polyisocyanate
hydrophylic, higher NCO functionality,high transparency.
New H ydrophylic P olyisocyanates PIC New generation:anionically modified HDI-trimers
