Melment F 4000
Melment F 4000
Melment® F 4000 is a free-flowing, spray dried powder of a sulphonated polycondensation product based on melamine. It is especially optimized for plastification and water reduction of cement-based mixtures.
Melment construction additives have a strong adsorbing and dispersing effect on mineral binder particles (such as cement or calcium sulphate particles) because of the high negative charge density of the synthetic polymer. However, it has no negative impact on the surface tension of the missing water.
