Esters of general formula R&#x2014;COOR, where R=9 to 23 C alkyl and R=methyl, ethyl, n-propyl or i-propyl are suitable as coalescing agents, in particular for the production of all types of coatings from an aqueous polymer or latex dispersion.

Use of Esters as Coalescing Agent

The invention relates to esters, the acid component of which is a monocarboxylic acid having 8 to 12 C atoms and the alcohol component of which is selected from the group of the pentanols, wherein said esters are excellently suited as coalescing agents.

Use of esters as coalescing agents

Pigment concentrates comprising a pigment, a liquid carrier medium and a dimerdiolalkoxylate, wherein a dimer portion of the dimerdiolalkoxylate comprises from about 36 to about 44 carbon atoms, and wherein the at least one dimerdiolalkoxylate has from about 1 to about 200 moles of alkylene oxide per mole of dimerdiol, are described in conjunction with methods of preparing the same.

Pigment concentrates containing dimerdiolalkoxylate additives, and methods of preparing same

Pigment concentrates comprising a pigment, a liquid carrier medium and a diol alkoxylate of the general formulae (I), (II) and/or (III) are described in conjunction with methods of preparing the same. The diol alkoxylates described and used herein are of the general formulae (I), (II) and/or (III):

Use of diol alkoxylates as additives for the production of pigment concentrates

Method of coating electrically conductive substrates

The invention is a method for improving the flow of particulate lacquer powders when the lacquer powders are coated on a substrate and the substrate heated to fuse the lacquer particles to provide a finished lacquer surface on the substrate. The flow control agent is an oxazine, oxazoline, oligoxazine or oligoxazoline and salts of the compounds with protonic acids. The flow control agents when included in power lacquer formulations improve the flow of the lacquer when the powder lacquer coated substrate is heated to fuse the coating.
