Abstract:
This invention relates to compositions comprising a polyisocyanate having ionic groups or polyether groups and at least one member selected from the group consisting of a naturally occurring polymer, a polysiloxane graft copolymer, a water-dilutable synthetic polymer and a cationic polymer or a naturally occurring polymer and at least one member selected from the group consisting of a polysiloxane graft copolymer, a water-dilutable synthetic polymer and a cationic polymer.
Abstract:
Graft polymers of unsaturated monomers onto anionically modified polyureas are outstandingly suitable as binders in the coating of any desired substrates, for example leather.
Abstract:
Textiles can be finished in a wash- and cleaning-resistant manner by impregnation if aqueous dispersions are employed for this purpose which contain reactive copolymers and/or cocondensates having perfluoroalkyl groups and water-dispersible polyisocyanate mixtures whose NCO groups are not blocked.
Abstract:
The new vinyl polymer dispersions are obtainable by free radical polymerisation of olefinically unsaturated monomers in the presence of a cationic polyamidoamine which has been rendered hydrophobic, and can be used as sizing agents for paper which are distinguished, in particular, by their shear, electrolyte, heat and storage stability.
Abstract:
Activator formulations which contain copolymers of (meth)acrylonitrile, styrenes, acrylates and/or unsaturated acids as binders are excellently suitable for preparing nonmetallic substrate surfaces for electroless metallization.The metal deposits produced are notable for good bond strength.
Abstract:
The invention relates to a process for the production of coatings using a coating composition containing as binder optionally blocked lacquer-grade polyisocyanates in combination with polyhydroxy polyacrylate resins based on copolymers of certain hydroxy alkyl(meth)acrylates, methyl methacrylate, 2-ethylhexyl acrylate and, optionally, (meth)acrylic acid, wherein the molecular weight is in the range from about 30,000 to 80,000, the content of low molecular weight constituents having molecular weights of at most about 3000 amounts to between 3 and 15% by weight, the molecular heterogeneity factor amounts to between about 1.0 and 10.0, and the parameter for the chemical heterogeneity of the copolymer is between 0 and about 0.06.
