摘要:
Activator formulations which contain an aromatic polyurethane as binder are highly suitable for the preparation of non-metallic substrate surfaces for currentless metallization.The metal coatings produced are distinguished by good adhesion.
摘要:
New polyisocyanate-polyaddition compounds, a process for their preparation and their use as wetting or dispersing agents for the incorporation of solids, in particular pigments, in lacquer or synthetic resin formulation.
摘要:
Process for the preparation of naphthalene-1,8-dicarboximide which is optionally substituted in the naphthalene ring, characterized in that naphthalene-1,8-dicarboxylic anhydride which is optionally substituted in the naphthalene ring is reacted with an ammonium salt in an aqueous medium at a pH near to the neutral point, the reaction mixture is then acidified to a pH of 1 to 4 and the pH is subsequently adjusted to a value near to the neutral point.
摘要:
Pigment preparations which contain an organic pigment and/or carbon black and a surfactant from the sulphosuccinic acid ester and/or alkylbenzenesulphonate series and which have been dried, if appropriate after wet comminution, by spray- or freeze-drying from an aqueous medium, and the use of these preparations for pigmenting high molecular weight organic material, in particular thermoplastics.
