901 is a cycloaliphatic modified curing agent offering a long early working time, fast final cure and high gloss. Cured products show excellent toughness, water resistance and chemical resistance — the properties that define a premium epoxy tile grout.
Product overview
Epoxy grouts live a hard life: constant moisture, detergents, abrasion and foot traffic. 901 gives grout formulators the full package — enough open time to tool long joints comfortably, then a fast set that resists early staining, and a cured surface that keeps its gloss after months of wet scrubbing.
The cycloaliphatic backbone also keeps the cured joint tough and slightly flexible, absorbing tile movement without cracking, while its chemical resistance shrugs off household cleaners and diluted acids.

Handling & safety
Keep containers sealed during storage and after opening: curing agents absorb moisture and CO₂ from air. Slight turbidity or surface skinning is normal and does not affect performance.
Run small-scale trials under your specific application conditions before large-scale use; usage and environmental conditions are beyond our control.
Store sealed in the original container in a cool, dry, well-ventilated area away from ignition sources. Shelf life: 12 months.
20 kg and 200 kg net packaging.
Amine products may cause skin sensitisation. Wear gloves; wash skin contact immediately with plenty of water.
