DEFOMEX AP 188 avoids and/or reduces the foam formation during the preparation and the application of the compounds and can destroy the persistent foam too.
Therefore during the preparation of i.e. special repair mortars, self-levelling systems, flooring screeds, crack fillers, the use of DEFOMEX AP 188 ensures to reduce the secondary effects due to high levels of entrained air, like decreasing some mechanical properties, such as compressive strength (Source: CHEMICAL ADMIXTURES FOR CONCRETE).
