METHOD FOR MAKING A PARTICULATE PRODUCT CONTAINING NONIONIC SYNTHETIC ASSOCIATIVE THICKENER AND DISSOLUTION PROMOTION WATER SOLUBLE ADDITIVE
The presently disclosed and claimed inventive concept(s) relates to a method for making a particular product comprising a nonionic synthetic associative (NSAT) rheology modifier and a dissolution promotion water soluble additive. The method comprising the steps of: (a) obtaining the NSAT theology modifier and the dissolution promotion water soluble additive; (b) melting the NSAT theology modifier and the dissolution promotion water soluble additive; (c) mixing the molten NSAT theology modifier and the dissolution promotion water soluble additive; and (d) producing the particulate product from step (c). The NSAT rheology modifier is selected from the group consisting of hydrophobically-modified ethoxylated urethane (HEUR), hydrophobically-modified polyethylene glycol (HMPEG), and hydrophobically-modified polyacetal-polyether (HMPAPE). The particulate product prepared from the method is incorporated into a waterborne paint formula.
