  • ASSOCIATIVE ACRYLIC THICKENING AGENT CONTAINING POLYGLYCEROLS AND ITS USE TO INCREASE THE OPEN TIME OF THIN OR THICK FILMS
    Publication number: 20130116377
    Abstract: The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are in incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, and traces of brushes and filling-knives.

  • USE OF GLYCEROL AS AN AGENT TO IMPROVE THE SELF-DISPERSING PROPERTIES OF A MINERAL MATERIAL TO BE ADDED TO AN AQUEOUS COMPOSITION
    Publication number: 20130056566
    Abstract: The invention consists of the use, during a mineral substance dry-grinding step, of formulations containing glycerol and/or polyglycerols as agents for improving the auto-dispersing characteristic of the said mineral substance in an aqueous composition. The immediate viscosity of the final composition is thus lowered and maintained stable over the course of time. In addition, the amount of foam formed during the dispersion in water step is reduced.

  • Method for formulating agrochemical active ingredients so as to regulate their release kinetics, protect them from outside stresses, and keep their users safe
    Patent number: 8354466
    Abstract: The invention pertains to a new method for formulating any agrochemical active ingredient so as to protect the user, protect this active ingredient from outside stresses, and control its release kinetics. It relies on the use of acrylic and thickening emulsions with a pH greater than five and containing hydrophobic groups in order to trap said active ingredient. The invention also pertains to the various embodiments of the active ingredient thereby formulated: a mixture in water of that active ingredient with these thickening emotions, a dispersion of solid particles of these polymers and this active ingredient after a certification, and the solid particles obtained in a dried state after the water has been removed. Finally, the invention pertains to the use of these various formulations in order to protect and active ingredient, protect its user, and slow its release kinetics.

  • Use of an acrylic dispersing agent—associative thickener pair in an alkide paint for improving the retention of its gloss level
    Patent number: 8329809
    Abstract: The invention consists of the use, in an alkide resin formulation in an aqueous phase, of a dispersing agent/thickener pair: the dispersing agent is a copolymer of (meth)acrylic acid with an oxyalkylated monomer possessing a polymerizable function and terminated by hydrogen or an alkyl group having from 1 to 4 carbon atoms, the thickener is an associative thickener containing at least one hydrophobic group which is a polystyrylphanyl, preferentially chosen from among distyrylphenyl, tristyrylphenyl, and mixtures thereof, and which is very preferentially tristyrylphenyl. This combination makes it possible to improve the brightness level retention of the paint film over time, while ensuring that the aqueous formulation has the desired rheology.
