Product

Berolan LP-W4DF is a surface active agent that works as an efficient air entrainer and plasticizer in different formulations for building materials based on gypsum, cement or lime. Berolan LP-W4DF is well suited as wetting agent in various areas of application where reduction of surface tension is essential. Berolan LP-W4DF has excellent flow properties and by that dosing accuracy may be improved. It is also developed to improve handling as dust generated is reduced remarkably. Berolan LP-W4DF imparts improved wetting and dispersion properties for typical mixes applied in the building industry, less tackiness as well as better workability, increases frost resistance and pump ability. The product incorporates uniform, small and stable air bubbles into various mixtures. Low-dust and excellent flow properties during dosage. Normal dosage is 0.005 – 0.05 % sbwc. Necessary dosage to obtain a specified air content depends of binder type, mixer type, w/c ratio, aggregate grading and fines (< 0 – 25 mm). It is always advisable to do test trials to optimize the dosage of air entrainer.
