Composition comprising a latex and a HEUR thickener |
| 摘要 |
The present invention relates to a composition comprising stable aqueous dispersion of polymer particles with acorn morphology, a hydrophobically modified ethylene oxide urethane based rheology modifier (HEUR) and a substantial absence of pigment particles with a refractive index in the range of from 2.0 and 3.0. The composition imparts improved HEUR efficiency for coating compositions such as deep base coating compositions. |

1. A composition comprising 1) a stable aqueous dispersion of polymer particles having a particle size as measured by dynamic light scattering in the range of from 70 nm to 300 nm, wherein the polymer particles have a core-shell morphology wherein the core protuberates from the shell; 2) a hydrophobically modified ethylene oxide urethane based rheology modifier; 3) an extender; and 4) less than 5% pigment volume concentration of pigment particles with a refractive index in the range of from 2.0 and 3.0. |
