This invention provides water-based compositions, particularly coating, ink, and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of certain cyclic urea compounds of the structure
where R is a C6 to C12 alkyl group or R''O-(CH2)m-, R' is hydrogen or methyl, R'' is a C4 to C12 alkyl group, m is 2-4 and n is 1 or 2.
本发明提供了
水基组合物,特别是涂料、油墨和农用组合物,通过加入一定量的降低表面张力的某些环状
脲化合物,从而降低了平衡表面张力和动态表面张力。
其中 R 是 C6 至 C12 烷基或 R''O-(
CH2)m-, R' 是氢或甲基,R''是 C4 至 C12 烷基,m 是 2-4 和 n 是 1 或 2。
