MC-DUR 1321 flex is a new epoxy resin from MC-Bauchemie that can be used as a wear layer in the OS 8 surface protection system in accordance with the German TR-IH guideline and DIN EN 1504-2. According to the manufacturer, it offers very good static and dynamic crack bridging.
Wear-resistant OS 8 systems that provide additional safety through crack bridging are currently in particularly high demand, says MC-Bauchemie, based in Bottrop, Germany. With MC-DUR 1321 flex, slip-resistant wear layers can be produced in the OS 8 system. According to the manufacturer, they offer both static crack bridging (class A3 according to DIN EN 1062-7; >0.7 mm at -10 °C) and dynamic crack bridging (class B3.1 according to DIN EN 1062-7; 0.3 mm at -10 °C). In addition, the OS 8 MC-DUR 1321 flex system achieves high wear resistance after 15,000 cycles in the Parking Abrasion Test (PAT).
Christian Nöcker, product manager at MC, says: “Whether in multi-storey car parks, on ground slabs, intermediate decks or ramps – the new coating makes it possible to create robust wear layers for safe driving and walking.”
Application as an OS 8 system
For application as an OS 8 system, the surface is first primed with MC-DUR 1320 VK and broadcast with quartz sand while still fresh. No earlier than twelve hours and no later than 24 hours after priming, MC-DUR 1321 flex is applied with a notched or pin trowel and then fully broadcast with quartz sand, as specified by MC. After the excess quartz sand has been removed the following day, the surface receives a top seal with the epoxy resin coating MC-DUR 1322.
