Tri-carboxylic compounds as low-VOC coalescing agents and plasticizing agents
View Patent ↗A tri-carboxylic compound of Formula (IA) optionally in combination with a compound of Formula (IIA) behaves as a low-VOC, low odor coalescing agent, while a tri-carboxylic compound of Formula (IA) in combination with a compound of Formula (IIB), or alternatively, a tri-carboxylic compound of Formula (IB) in combination with a compound of Formula (IIA) exhibits dual coalescing and plasticizing properties. A tri-carboxylic compound of Formula (IB) optionally in combination with a compound of Formula (IIB) behaves as low-VOC, low odor plasticizing agent.
1. A low-VOC coalescing composition comprising:
a compound of Formula (IA)
wherein:
R 1 , R 2 and R 3 are each independently C 1 -C 6 alkyl;
and a compound of Formula (IIA)
R 4 —OOC—X—COO—R 5 (IIA),
wherein:
R 4 and R 5 are each independently C 1 -C 6 alkyl; and X is —(CH 2 ) 2 —, —(CH 2 ) 3 — or —(CH 2 ) 4 —; and
wherein the composition has ratio of Formula IA to Formula IIA from 1:9 to 9:1 by weight.
2. The composition according to claim 1 , wherein R 1 , R 2 and R 3 are each independently selected from the group consisting of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, isopentyl and hexyl.
3. The composition according to claim 1 , wherein R 4 and R 5 are each independently selected from the group consisting of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, isopentyl and hexyl.
4. The composition according to claim 1 , wherein both R 4 and R 5 are methyl and X is —(CH 2 ) 2 —, —(CH 2 ) 3 — or —(CH 2 ) 4 —.
5. A coating composition comprising:
the low VOC coalescing composition according to claim 1 ; and
a binder, a pigment, a pigment extender, a colorant, a tint, a dye, a surfactant, a suspension additive, an antifoaming agent, a biocide, a fungicide, a particulate, a cementitious composition, a texturizing composition, a water-miscible solvent, a pH adjuster, a crosslinking agent, a thickening agent, a viscosifier, a filler, a freeze-thaw additive, a flattening additive, a pigment grind additive, an opacifier, a stabilizer, a film preservative or any combination thereof.
6. The coating composition according to claim 5 , wherein R 1 , R 2 and R 3 are each independently selected from the group consisting of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, isopentyl and hexyl.
7. The coating composition according to claim 5 , wherein the coating composition is a paint, ink, adhesive, toner, sealant, stain, glaze, primer or carpet backing.
8. The coating composition according to claim 5 , wherein the coating composition is a latex paint composition.
9. The coating composition according to claim 5 , wherein the composition has a VOC level of 0-100 g/L.
