Dispersants for coating compositions isocyanatoalkylacrylates as inorganic pigment dispersant on metal substrates

Dispersants which improve the gloss of acrylic paints are prepared by reacting the isocyanate groups of monomeric polyisocyanates or isocyanate acrylate polymers with (1) fatty amines, (2) lower alkylamines or alkanolamines and (3), optionally, aminosilanes. A formula for the dispersants may be writ...

Zusammenfassung:	Dispersants which improve the gloss of acrylic paints are prepared by reacting the isocyanate groups of monomeric polyisocyanates or isocyanate acrylate polymers with (1) fatty amines, (2) lower alkylamines or alkanolamines and (3), optionally, aminosilanes. A formula for the dispersants may be written as: isocyanate residue, A is fatty amine residue with a=20-80, B is lower alkylamine or alkanolamine residue with b=80-20, and C is aminosilane residue with c=0-40, the sum of a+b+c=100, the (mole) percentage of isocyanate groups replaced.
