The invention relates to a process for the preparation of a gel material which is not free-flowing, is reversibly transparent as a function of temperature and comprises nonionic and/or nonionically acting surfactants as clouding components. The preparation of the gel material can be integrated into the customary production process for laminated glazing in a simple manner and produces frost-stable glazing which can be employed universally indoors and outdoors. When applied, the strength of the system is so high that it is no longer free-flowing at all and bulging of the laminated pane and running-out are therefore no longer possible.

The invention provides a process for the preparation of large-particle, aqueous plastic dispersions, which permits targeted adjustment of particle size. The process comprises a system which controls the particle size and comprises the step of polymerizing a monomer in the presence of an anionic emulsifier; a substantially non-branched, nonionic, water-soluble polymer auxiliary; and alkali metal and/or ammonium ions not bonded to emulsifier. The polymer auxiliary can be prepared reproducibly with regard to its agglomerating effect.

The object of the invention is a process for the production of flat varnishes based on powder coatings of 1,2-epoxy compounds with at least one 1,2-epoxy group in the molecule and a lower melting point of &gt;40.degree. C., salts of aromatic carboxylic acids with 3 and more carboxyl groups and imidazolines as curing agents, as well as the usual additives and the application of the powdered varnish upon the objects to be varnished and heating of these objects to temperatures of 160.degree.-240.degree. C., whereby the salt of 2-phenyl-methyl-.DELTA.2-imidazoline and trimellitic acid is substituted up to 60 mole % by a salt of 2-phenyl-.DELTA.2-imidazoline and trimellitic acid.

Epoxy resin-diammonium salt emulsions are based on a liquid epoxy resin, a latent curing agent, and an emulsifier. The latent curing agent comprises diammonium oxalates and the emulsifiers are C.sub.8 - to C.sub.14 - alcohols and/or the adducts thereof with up to 10 ethylene oxide groups. A process for the production of such emulsions is provided. They are useful in epoxy resin mortars and epoxy resin-cement mortars, and for the sealing of concrete surfaces.

Emulsion based on epoxy resins and diammonium salts and its preparation

An epoxy resin-polyammonium salt emulsion is based on a liquid epoxy resin, a latent curing agent, an emulsifier, and water, wherein
