Water dispersible polyisocyanate composition and its uses

   
   

The present invention relates to a water dispersible polyisocyanate composition comprising (a) an aliphatic polyisocyanate or a mixture of aliphatic polyisocyanates or a mixture of aliphatic polyisocyanates with other polyisocyanates; and (b) a reaction product of component (a) with a component selected from the group consisting of: (ii) a polyether diol or triol or a mixture thereof wherein a weight ratio of ethylene oxide (EO) to propylene oxide (PO) of the polyether diol and triol is greater than about 60:40, and the polyether diol has a molecular weight of about 300 to 1600 g/mole, and the polyether triol has a molecular weight of about 450 to 2400 g/mole; and (ii) a mixture of polyether monol and polyether polyol, wherein the polyether polyol is selected from the group consisting of polyether diol, triol and a mixture thereof wherein a weight ratio of EO to PO of the polyether monol, diol and triol is greater than about 60:40, and the polyether diol and triol have the molecular weights as defined above.

Присытствыющий вымысел относит к составу polyisocyanate воды dispersible состоя из (a) алифатического polyisocyanate или смеси алифатических polyisocyanates или смеси алифатических polyisocyanates с другими polyisocyanates; и (b) продукт реакции компонента (a) при компонент выбранный от consist of группы: (ii) диол polyether или триол или смесь thereof при котором коэффициент веса окиси этилена (eo) к окиси пропилена (po) диола и триола polyether greater than около 60:40, и диол polyether имеют молекулярный вес около от 300 до 1600 g/mole, и триол polyether имеет молекулярный вес около от 450 до 2400 g/mole; и (ii) смесь monol polyether и полиола polyether, при котором полиол polyether выбран от диола polyether группы consist of, триола и смеси thereof при котором коэффициент веса eo к po monol polyether, диола и триола greater than около 60:40, и диол и триол polyether имеет молекулярные весы как определено выше.
