A method for creating a multi-functional additive for fusion powder coating compositions that is made from a binder system platform so as to replace the need for multiple conventional additives. The method calls for the multi-functional additive to be provided to fusion powder coating compositions by way of a carrier system selected from (3-aminopropyl) trimethoxysilane (TMS), silicon dioxide (at 45 to 55% active levels), and a flow aid comprising a polyethylene resin, a polyester hydroxyl resin, a polymeric curative, degassing agent, ricinoleic acid, and glass flake.

There is provided a water-based alkaline composition for forming an insulating layer of an annealing separator on a soft magnetic alloy, this composition comprising ceramic particles with a particle size of less than 0.5pm and at least one polymer dispersion as a binding agent, the polymer dispersion comprising one or more mixed polymerisates from the group made up of acrylate polymers, methacrylate polymers, polyvinyl acetate, polystyrene, polyurethane, polyvinyl alcohol, hydroxylated cellulose ether, polyvinyl pyrrolidone, and polyvinyl butyral, and having a pH value of between 8 and 12, preferably between 9 and 11.

The invention relates to a fatty amide which is a di- or triamide based on a polyether diamine or triamine which can be used as organogelator and in particular as rheology additive, said amide comprising a specific mixture of hydroxylated fatty acids and short hydroxylated acids. The invention also relates to a formulation composition using said fatty amide as rheology additive and to its use with this aim in coating, adhesive or PVC plastisol compositions and in particular transparent or non-transparent mastic compositions. Said rheology additive has the advantage of not needing a specific activation process before use, in contrast to the other known fatty amide additives based on hydrogenated castor oil derivatives.
