Abstract: The present invention relates to a process for the preparation of a composite for thermal insulation comprising at least layers (L1), (L2) and (LB), the process comprising the steps of providing layer (L1) containing from 25 to 95% by weight of aerogel and from 5 to 75% by weight of fibers and from 0 to 70% by weight of fillers and layer (L2) containing from 25 to 95% by weight of aerogel and from 5 to 75% by weight of fibers and from 0 to 70% by weight of fillers; applying a composition (C1) comprising an inorganic binder on one surface of the layer (L1) or layer (L2) or layer (L1) and (L2), and combining layer (L1) and layer (L2) in a manner that composition (C1) is located between layer (L1) and (L2), wherein composition (C1) is applied in the form of a, as well as a composite for thermal insulation comprising at least layers (L1), (L2) and layer (LB) which is located between layers (L1) and (L2) and the use of said composite for thermal insulation.

Abstract: The invention relates to a process for modifying polymer particles of an aqueous polymer dispersion in which positively or negatively charged polymer particles are provided with an inorganic salt shell. The inorganic shell leads to an improved drying ability and storage stability of the latex and improves the storage stability of the resulting polymer powder. The obtained polymer powder exhibits an improved viscosity and faster skin-forming time in the final application and is therefore particularly useful in a building material composition.
