  • Publication number: 20140031470
    Abstract: A coating composition comprising a binder, a carrier, a pigment, cations selected from the group consisting of alkali metal cations, ammonium cations, and mixtures thereof, and at least one diamino alcohol selected from the group consisting of compounds of Formula I and compounds of Formula II. The present invention also provides a method for reducing the volatile organic compound (VOC) content of a coating composition having a binder, a carrier, and a pigment, which comprises including in the coating composition the aforesaid A) cations and B) at least one diamino alcohol. The diamino alcohol may be of Formula I: wherein R1 and R2 are independently C1-C10 alkyl, or R1 and R2, together with the carbon to which they are attached, form a C3-C12 cycloalkyl ring optionally substituted with C1-C6 alkyl. For example, the compound of Formula I may be 2-(2-amino-2-methylpropylamino)-2-(hydroxymethyl)propane-1,3-diol.
