Tradeco is a modified hydraulic lime binder, manufactured by Saint Astier in France. It is based on NHL 3.5 with the addition of a small proportion of white low sulfate cement and additives to improve workability. Tradeco is formulated for use with low strength backgrounds. As a modified hydraulic lime, Tradeco will develop its compressive strength of the mansonry unit. This makes it an ideal choice for building with low strength masonry units and blocks. Tradeco also offers good elasticity and water retention, setting time, low capillarity and excellent breathability.
