Abstract
The present invention is directed to a polyisocyanate preparation dispersible in water and having an average NCO functionality of about 2.0 to 3.5 which contains PA0 (a) an aliphatic polyisocyanate or a mixture of aliphatic polyisocyanates; and PA0 (b) a quantity of an emulsifier sufficient to ensure the dispersibility of the polyisocyanates. The present invention is also directed to the use of this polyisocyanate preparation as an additive for aqueous adhesives based on polymers dispersed in water.
