Operational safety measures:


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.

The operator may be exposed to the HARTEDUR 115 under the following conditions:

1. When the weighing or feeding, the dust that floats out.

2. Preparation of NDI prepolymer or excess NDI produced steam or fumes when poured.

Storage:


Note: HARTDUR 115 is very sensitive to moisture. Because all diisocyanates react with water to form insoluble urea derivatives. HARTDUR 115 should be stored in a cool and dry condition. Immediately after use, it should be sealed to avoid failure. Under suitable external conditions, the product is valid for 6 months.

package:


Standard container: paper drum lined with polyethylene bag, net weight 20kg/barrel.
