PROCESSING

After mixing according to the indicated ratio, carry out impregnation of the reinforcements.
To ensure an optimal use and a good impregnation, please use packaging stored at a temperature
above 20 C.

CURE CONDITIONS
In order to avoid any risk of distortion or tooling shrinkage a precise curing cycle must be observed.
Demolding takes place only after a 24 hour R.T. minimum plus eight hour pre-curing at 55 C-60 C.
For full properties require an additional full post-cure.

HANDLING PRECAUTIONS

Normal health and safety precautions should be observed when handling these products :
Ensure good ventilation.
Wear gloves, glasses and protective clothes.
For further information, please consult the Safety Data Sheets.

STORAGE CONDITIONS

Shelf life of resin and hardeners are 12 months in original, unopened container stored in a dry 65-
77 F (18- 25 C) place.
Repeated exposure to low temperatures during storage may cause the resin to crystallize. If this
occurs, warm the resin to 120 – 140 F (49- 60 C) and stir to dissolve the crystals. Any opened can
must be tightly closed.
