CONTOPP®

Function

• Significant reduction in drying shrinkage of cement screeds
• Reduces the surface tension of the mixing water to minimize the suction forces on the capillary walls at the same time, thereby reducing the resulting shrinkage stress.
• No change in compressive and flexural bending strength

Application area

• For producing semi-dry sand/cement screeds and cement flowing screeds with reduced drying shrinkage.
• Proven shrinkage class SW2 (0,2mm/m – 0,5mm/m = shrinkage reduced) according to DIN 18560-1. Test of shrinkage according to DIN EN 13892-9 over 90 days in combination with other additives from the CONTOPP® series is available.
• Expressly recommended when manufacturing bonded screeds and terrazzo screeds.
