Abstract
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 alkylated aminoether compounds of the structure R—HN(CH2)p[O(CH2)n]mO(CH2)qNH—R′ where n is 2-6, m is 0-4, and p and q are 2-6, and R and R′ independently are an alkyl group comprising 5 to 18 carbons, preferably which is branched or in which the point of attachment to nitrogen is on a nonterminal carbon.
Claims9
In a method for applying a water-based composition to a surface to partially or fully coat the surface, the composition containing an organic compound and an effective amount of a surfactant for reducing the dynamic surface tension of the composition, the improvement which comprises employing as the surfactant an alkylated aminoether of the structure
- R—HN(CH2)p[O(CH2)n]mO(CH2)qNH—R′
- where n is 2-6, m is 0-4, and p and q are 2-6, and R and R′ independently are an alkyl group of 5 to 18 carbons.
