DISPERSION-POWDER COMPOSITIONS CONTAINING VINYL AROMATIC-1,3-DIENE COPOLYMERS USED IN SELF-LEVELING FLOOR COATINGS AND SCREEDS

摘要

The present invention relates to water-redispersible dispersion-powder compositions stabilised with protection colloids and used in self-leveling floor coatings and screeds. This invention is characterised in that the dispersion-powder composition contains: a) a base polymer selected from the group of vinyl aromatic-1,3-diene polymers; b) from 2 to 25 wt % relative to the base polymer of at least one protection colloid; c) from 3 to 30 wt % relative to the total weight of the polymer components of a fine-particle non-stick agent; and d) from 0.1 to 10 wt % relative to the base polymer of other additives.
