Curing Agent NDI
Chemical composition: 1,5-naphthalene diisocyanate or naphthyl 1,5 diisocyanate
HARTDUR 115 is pure 1,5-naphthalene diisocyanate (NDI) and is a fine, white or light yellow to off-white irregular flaky crystal. At room temperature, the vapor pressure is lower than 10-4 mbar. Federal Republic of Germany regulations: NDI content should be less than 0.02ppm (0.18mg/m3) in the working environment (even if it is not exceeded for a short time). Due to special reactivity, NDI is recognized. Care must be taken for dangerous objects.
The potential hazard of HARTDUR 115 is the dust, steam and fumes formed during use.
