MasterEmaco S 440MC is a shrinkage-compensated, one-component, femto cementitious material
MasterEmaco S 440MC is intended for complex architectural regular maintenance ranging in depth from 3/4" (19 mm) to full depth. Low dusting for additional worker security and convenience. Because of its flowability, MasterEmaco S 440MC is ideal for pumping or pouring into heavily populated areas.
MasterEmaco S 440MC provides excellent freeze/thaw resistance for sturdiness in chilly, moist climates. Its high early strength allows for faster form abolishment. In both the plastic and hardened states, the dual flexibility of MasterEmaco S 440MC compensates for deformation. Its low permeability provides protection against carbon dioxide and chloride encroachment.
