Abstract

The invention is comprised of a coalescent and non-ionic surfactant blend additive for use in water-based architectural coating formulations. The dual-function blend is produced by reacting 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate with ethylene oxide in the presence of a basic catalyst and separating the desired ethoxylated coalescent and non-ionic surfactant blend from the reaction product.

First claim

We claim:

1. A coalescent and non-ionic surfactant blend comprising:
a) structure (1);

b) structure (2); and

c) structure (3);

wherein n is 1 to 5.

2. The coalescent and non-ionic surfactant blend of claim 1 further comprising a mixture of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, di-isopropyl ketone, isobutyl isobutyrate, isobutanol, and 2-isobutoxy-ethanol.

3. A composition derived by reacting 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TXOL) with ethylene oxide in the presence of a catalyst, at temperatures of from about 100° to 200° C., and under pressures of from about 345 kPa to 1800 kPa and separating ethoxylatedstructures (1), (2) and (3) from the reaction mixture:

wherein n is 1 to 5.

4. A coating composition comprising:
A. at least one latex compound;
B. at least one pigment;
C. a coalescent and non-ionic surfactant blend comprising:
a) 10 to 60 weight percent structure (1);

b) 5 to 50 weight percent structure (2);

c) 0 to 30 weight percent structure (3); and

based on the total weight of said coalescent and non-ionic surfactant mixture and wherein n is 1 to 5.

5. The coating composition of claim 4 wherein said latex compound is selected from the group comprising acrylic latex, vinyl acrylic latex, vinyl versatate vinyl acrylics latex, ethylene vinyl acetate latex, and styrene acrylic latex.

6. The coating composition of claim 4 wherein said pigment is TiO 2 , calcium carbonate, talc, silica, nepheline syenite, or clay.

7. A coalescent and non-ionic surfactant blend for use in aqueous architectural coatings comprising:
a) 10 to 60 weight percent structure (1);

b) 5 to 50 weight percent structure (2);

c) 0 to 30 weight percent structure (3); and

d) the balance to 100 weight percent a mixture of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, di-isopropyl ketone, isobutyl isobutyrate, isobutanol, and 2-isobutoxy-ethanol and wherein n is 1 to 5.
