Abstract
The use of an amine functional polymer, including salts thereof, as a rheology modifier for solvent-based paints, inks, filled thermosetting resins and thermosetting resin-based gelcoats whereby the amine functional polymer contains not less that 42% by weight of the residue of one or more amine-containing monomers, or salts thereof, relative to the weight of the polymer. Preferably the amine functional polymer is obtainable from two or more monomers which contain at least one ethylenically unsaturated group such as styrene and 2-dimethylaminoethylmethacrylate.
Claims24
The use of an amine functional polymer, including salts thereof, as a rheology modifier for solvent-based paints, inks, filled thermosetting resins and thermosetting resin-based gelcoats whereby the amine functional polymer contains not less than 42% by weight of the residue of one or more amine-containing monomers, or salts thereof, relative to the total weight of the polymer.
An amine-functional polymer which comprises not less than 42% by weight of the polymer of a residue of an amine-containing monomer having an ethylenically unsaturated group and a residue of styrene, including salts thereof.
An amine-functional polymer which comprises not less than 42% by weight of the polymer of a residue of an amine-containing monomer having an ethylenically unsaturated group and a residue of a C1-16-alkyl (meth) acrylate, including salts thereof.
A coating composition comprising a film-forming binder resin, an organic liquid and an amine functional polymer which contains not less than 42% by weight of the residue of one or more amine containing monomers, or salts thereof, relative to the total weight of the polymer.
A composition comprising a film-forming binder resin, a particulate solid, an organic liquid, an organic compound containing two or more anionic groups and an amine functional polymer which contains not less than 42% by weight of the residue of one or more amine-containing monomers, or salts thereof, relative to the total weight of the polymer.
A composition comprising a film-forming binder resin, an organic liquid, an organic compound containing two or more anionic groups and an amine functional polymer which contains not less than 42% by weight of the residue of one or more amine-containing monomers, or salts thereof, relative to the total weight of the polymer.
A millbase, paint or ink comprising a film-forming binder resin, an organic liquid, a pigment and an amine functional polymer which contains not less than 42% by weight of the residue of one or more amine-containing monomers, or salts thereof, relative to the total weight of the polymer.
