Berolan LP 70 is a strongly surface-active air-entraining admixture and plasticizer. It has been developed especially for use in mortars based on cement, gypsum or lime. It leads to a better plaster yield, to improved workability and improves the wetting of the mortar. Related to the longer open timea tearing of the plaster surface and skin formation will be reduced. It decreases the wear of mixing units, the tendency to lumping, and the shrinkage. Irritation of the respiratory organs has been minimized. CE-Nr.: 1139-CPD-0802/09

Berolan LP-W1 is a high-performance air-entraining (sodium lauryl sulfate) agent in powder formand an excellent wetting and plasticizing agent for mortar and plasters. Berolan LP-W1 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-W1 effects the formation of particularly fine, stable air bubbles, thereby condsiderably 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-W1 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 lies 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. CE-Nr.: 1139-CPD-0802/09

Berolan LP 80 is a strongly surface-active air-entraining admixture and plasticizer. It is used as an air-entrainer for various cement-based systems, specially qualified for renovation render. Berolan LP-80 may be added as delivered. The required dosage may vary over a wide range (0.05 to 0.5 %) and should therefore be evaluated in suitable tests. For first trials we recommend 0.2 % Berolan LP 80 referred to dry substrate.
