Applications and Propoerties

Together with standard liquid epoxy resins (EEW 170-195 [g/Eq]) clear, viscoplastic moulds are formed. Due to the low heat of reaction these moulds basically do not shrink. Therefore they are ideally suited for waterproofed sealings, particularly for ceiling openings.

These properties are also especially desired in bondings of filters in pipelines. The repairing of sewage systems with liner technology can be performed very efficiently with MERGINAMID A 296. The cured moulds can be machined and shape cut. Also they are resistant against acids as well as lye and only soften at high temperatures.
