Curable composition for production of coatings for thermal, electrical and/or acoustic insulation

A process for producing a curable composition suitable for production of coatings for thermal or acoustic insulation, the process comprising:

• mixing at least one aqueous binder,
• a first component based on spray-dried fumed silica pellets,
• at least one second component selected from the group consisting of silicon dioxides, pellets based on pyrogenically produced silicon dioxide, silica aerogels, silicate glass (foamed glass/expanded glass), hollow silicon dioxide particles (hollow glass beads), perlite pellets, vermiculite pellets, polymers, and mixtures thereof, and
• the following may optionally be added subsequently to the mixture:
• film formers, pigments, fillers, thickeners, fibres, protective colloids, dispersants, wetting agents, preservatives, and/or defoamers.
