Abstract
The present disclosure relates generally to a particulate product. The particulate product comprises coarse particles of a nonionic synthetic associative thickener (NSAT) rheology modifier. The NSAT rheology modifier is selected from the group consisting of hydrophobically-modified ethoxylated urethane (HEUR), hydrophobically-modified polyacetal-polyether (HMPAPE), and combinations thereof. The particulate product is incorporated into a waterborne paint formula.
Claims29
A particulate product, comprising a nonionic synthetic associative thickener (NSAT), wherein the NSAT has an average particle size in a range from about 0.5 to about 5.0 mm and at least about 10% by weight of the NSAT is retained on a 1.18 mm sieve (No. 16) measured according to ASTM C136-06 Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates.
