MELFLUX SELECT 5421 F

MELFLUX SELECT 5421 F is a free-flowing powder based on modified polycarboxylic ether (PCE). MELFLUX SELECT 5421 F is optimized for deviations in sand qualities. It is especially robust by clay impurities in sands. MELFLUX SELECT 5421 F is a highly efficient superplasticizer developed especially for flowing floor screeds (e.g. calcium sulphate or Ordinary Portland cement-based screeds). MELFLUX SELECT 5421 F has a very low content of volatile organic components (VOC) and is therefore useful to formulate flowing floor screeds according to e.g. EMICODE® (very low VOC emission standard).
