Description

Damival 15120 OA00 with the hardener Damival 15174 OB01 is a 2-parts epoxy system, unfilled, with low viscosity

and long gel time at ambiant conditions. Cold curing.

Application

▪ Solventless varnish for impregnation of glass or polyester fibres, used in slot wedges of large generators

▪ Cold curing mastic when filled with our powder DAMIADD 8902

▪ Approved in medium and large generators industry

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.
