The present invention relates to the use of sequential copolymers (P), comprising at least one chain (C) capable of being obtained by micellar polymerization, for keeping solid particles (p) in suspension in a fluid (F) where said chain (C) is soluble.

Suspending agents obtained by micellar polymerization

Polymeric systems useful for maintaining particle dispersions for extended periods of time.

Polymeric systems for particle dispersion

The present disclosure provides polymeric systems that are able to undergo fast hydration and are useful for maintaining particle dispersions for extended periods of time.

An aqueous based coating composition comprising a fatty amine quaternary having the structure of formula (I): RRRRNXwherein R, R, R, and Rare independently selected from saturated or unsaturated, linear or branched, substituted or unsubstituted alkyl, aralkyl, or alkenyl groups comprising from 1 to 30 carbon atoms, whereby at least one of R, R, R, and Ris a C12-C30 group, and Xis an anion from an inorganic or organic acid, is provided. The fatty amine quaternary may contain ethoxy and/or propoxy groups. One or more of R, R, R, and Rmay be substituted and contain one or more hydroxyl substituents or ether linkages. Methods for imparting water resistance to a wood substrate having up to 100% moisture by applying a coating composition having the fatty amine quaternary of formula (I), and for preparing an aqueous coating composition comprising the fatty amine quaternary of formula (I) are provided. Also provided is a coated water resistant wood substrate comprising the fatty amine quaternary of formula (I).

Weatherproof aqueous wood coatings
