Abstract
A new class of compounds, namely diamino alcohols, is described, along with a process for their production and their use as dispersing additives for coating formulations.
Claims7
An aqueous coating formulation comprising:
- (a) 25-99% by weight of an aqueous carrier comprising water and at least one non-halogenated resin;
- (b) up to 20% by weight of a pigment;
- (c) 0.01 to 5% by weight of a diamino alcohol compound having the formula:
- wherein the amine groups are primary amine groups and R is independently hydrogen, alkyl, aryl, or —CH2OH;
- R1 is independently hydrogen, alkyl, or —CH2OH;
- alternatively, R and R1 may be linked together to form a cycloalkyl;
- R2 is phenyl;
- R3 is independently hydrogen, alkyl, or phenyl or —CH2OH;
- R4 is independently hydrogen, alkyl, or —CH2OH;
- and alternatively, R3 and R4 may be linked together to form a cycloalkyl;
- wherein all weight percents are based on the total weight of the aqueous coating formulation.
