Processing

The gel time and the curing time depend on the mixed volume, the temperature and the thickness of the layer. Final

properties are depending on the curing level.

A too large amount of resin mixed with the hardener can create a strong exothermic reaction with a rapid increase of

temperature.

The resin is packed in cans of 0,5kg and the hardener in pre-dosed cans (0,275kg) to avoid any weighting operation.

Mixing ratio (resin/hardener):

Weight: 100 / 55

Packaging

Resin: 0.5kg cans in carton box of 12 cans (6kg)

Hardener: 0.275 cans in carton box of 12 (3.3kg)

Storage conditions – Shelf life

Resin: 24 months in original packaging, at maximum 25°C, protected from moisture. Possible storage at higher

temperature for short period of time. May crystallise below 5°C. In such case, warm up to 60°C until crystals disappear,

and stir before use.

Hardener: 12 months in original packaging, at maximum 25°C, protected from moisture. Possible storage at higher

temperature for short period of time.
