EPOXONIC® EX 1824 rapid


EPOXONIC® EX 1824 RAPID formwork resin is a solvent-free, dual component formwork resin with an epoxy resin amine basis and an especially low density. It is easy to make the resin flexible, and it has a high inner ductility, allowing the material to compensate for small amounts of mechanical tension. It was specially developed for underwater applications.

Areas of application

EPOXONIC® EX 1824 RAPID formwork resin is especially well suited to renovate damaged side branches in waste water, mixed, and rain water sewers in nominal widths between DN 150 and DN 800 using robots. Sewers can be made of stone, clinker, concrete, fibre cement, reinforced concrete, or PVC. Its characteristics are adjusted so as to quickly achieve complete filling when using formwork.

When used correctly (mill to create a grease-free surface), it creates a pressure-tight result which can bear heavy structural loads. EPOXONIC® EX 1824 RAPID FORMWORK RESIN can also be used in waste water sewers in airport areas, since it is resistant to kerosene and typical de-icing agents.
