Berolan LP-W2

Berolan LP-W2 is a pure sodium lauryl sulfate that has been spray-dried particularly finely. Due to the particularly high fineness, an excellent distribution in dry mortar can be achieved. This also leads to a particularly high effectiveness. Berolan LP-W2 is a high-performance air-entraining agent and an excellent wetting and plasticizing agent for mortar and plasters. Berolan LP-W2 is an excellent foaming agent and plasticizer for the manufacture of ready-to-use plasters, mortar compounds, and filling compounds containing gypsum, lime or cement. Berolan LP-W2 effects the formation of particularly fine, stable air bubbles, thereby considerably improving the General performance of resistance, water retention as well frost stability. Tendency towards contraction and crack formation is also reduced as is wear and tear to mixing apparatus and conveyors. Due to its surface active character Berolan LP-W2 additionally promotes wetting of binders and other ingredients, thus entailing a swifter wetting and dispersion and reducing the tendency towards aggregation during mixing. The necessary quantity depends on the desired effect but generally is between 0.005 – 0.1 %, calculated on the dry mix. In the majority of cases 0.01 % proves sufficient to obtain adequate aeration. The equipment available must also be taken into account, where batch operated mixers generally feed more air into the mortar. Through the purposeful air entrainment the yield is significantly improved. A very quick wetting ensures less entry of coarse air pores and reduced nodule formation (dry spots/knots).
