摘要:
A process for increasing the wetting rate of hydrophobic media with a wetting composition includes the steps of combining water and a heteric polyol to form the wetting composition, aging the wetting composition for an amount of time sufficient to increase the cloud point of the wetting composition to greater than 23° C., and applying the wetting composition to the hydrophobic media. The heteric polyol has the following formula:;X[Y(CH2CH2O)a(CH2CHCH3O)bH]c ;wherein X is an organic core derived from an initiator having at least two hydroxyl groups; Y is a heteric copolymer comprising at least two different alkyleneoxy units selected from the group of ethyleneoxy units, propyleneoxy units, and butyleneoxy units; the subscripts a and b are independently zero or a positive integer and at least one of a or b must be a positive integer; and the subscript c is an integer of two or greater.
