摘要:
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.

摘要:
The present invention relates to a dry mortar and a mortar slurry, and a method for producing semi-rigid coatings. In one embodiment, the dry mortar and/or mortar slurry comprises a cement, a very fine component, and a superplasticizer and is free of silica fume, wherein the mortar slurry can be applied at an asphalt framework temperature between 55 and 80 °C, and a compressive strength of at least 100 N/mm2 is reached after 28 days. In a further embodiment, the dry mortar and/or mortar slurry additionally contains a gelling agent to reduce the propensity of the mortar slurry to flow out.
