Overalls must be worn
Impervious gloves must be worn
Curing schedule is meant to be as a guide only and is subject to local conditions
To avoid exotherm, particular care must be taken with thick laminates
Ramp rates must not exceed 3.0°C (5.4°F)/min during initial cure and 0.3°C (0.5°F)/min during post cure
