TPR Systems R 17 mortar is a solvent-free 2-component methacrylic resin mortar with a high compressive strength and tensile strength in bending. It is characterized by very low linear shrinkage.
Because of its high strength, the mortar is suitable as a wear-resistant concrete coating for coating thickness of 6 – 20 mm. The low shrinkage rate enables even larger unevenness to be levelled out. The mortar surface resembles that of a fine exposed concrete and can be topped with suitable TPR coatings to ensure a decorative surface look. The hardening time is about 1 hour at +20 °C, and hardening takes place in temperatures ranging from -10 °C to +35 °C (approx. 1 – 3 hours). The very low viscosity enables rapid mixability and application to be achieved.
Special areas of use are on floors for traffic areas in industrial concerns which are subject to heavy mechanical stress and as a localised repair mortar for indoors and outdoors. Greater coat thicknesses can be achieved by adding further coarse aggregates (e. g. for ramps, rail bedding, filler and screed mortars, casting bridge bearings). Suitable coarse aggregates include non-absorbent mineral particles (e. g. quartz gravel) in the proportions listed in the table below. For large-volume applications, individual gravel stones up to 30 cm in diameter can be inserted. However, these should not touch each other, as otherwise this place will have an increased tendency to fracture.
