摘要:
The invention relates to the use of organofunctionally modified polysiloxanes containing phenyl derivatives as dispersants for preparing aqueous pigment formulations, paints, coating materials, and coatings. For the purposes of this invention the term “polysiloxanes” shall be understood to embrace oligomeric siloxanes as well.
摘要:
The invention relates to the use of particular phosphoric esters as emulsifiers and dispersants for pigments and fillers, based on polystyrene-block (b)-polyalkylene oxide copolymers. The invention provides block copolymeric phosphoric esters and their salts of the general formula (I) [R1O(SO)a(EO)b(CH2CHCH3O)c(BO)d]xPO—(OH)3−x (I) where R1=a straight-chain or branched or cycloaliphatic radical having 1 to 22 carbon atoms, SO=styrene oxide, EO=ethylene oxide, BO=butylene oxide and a=1 to

摘要:
The invention relates to phosphoric esters of the general formula (I): wherein x is 1 or 2; n is a number from 2 to 18; m and n are each a number from 2 to 100; k is a number from 2 to 4; R″ is H or a linear or branched alkyl radical which may be substituted by a functional radical; and R′ is an alkyl, alkaryl, alkenyl or a sulfopropyl radical. The invention further relates to the use of the phosphoric esters as dispersants for pigments and fillers in aqueous or organic media and in particular to methods of forming a highly filled sheet molding compound or bulk molding compound comprising the step of dispersing components of the molding compound with said phosphoric esters.

摘要:
The invention describes amine-amide-functional siloxanes and a process for the preparation thereof by the chemical reaction of SiOH-functional siloxanes with amino-functional silanes in the presence of carboxylic acid anhydrides.
摘要:
The invention provides low surface tension surfactants based on amino alcohol and also provides for their use in aqueous coating formulations, said surfactants being preparable by reacting at least one secondary amine of formula (I): with at least one diepoxide of formula (IV): and/or with at least one triepoxide of formula (IV): in essentially equivalent amounts of amine hydrogen atoms and epoxide groups.
摘要:
The invention relates to block-copolymeric polyalkylene oxides containing styrene oxide, obtained by alkoxylation, and their use as low-foam pigment wetting agents in aqueous pigment pastes with or without cosolvent and in aqueous and low-solvent coating materials and printing inks.
