7. Handling and Storage
Precautions to be Taken in storage and Handling: store in
tightly closed containers to prevent moisture contamination.
Do not reseal if contamination is suspected. If container is
exposed to high heat, it can be pressurized and possibly
rupture. Diisocyanates react slowly with water to form co2
gas. This can cause sealed containers to expand and
possibly rupture. Avoid contact with skin and eyes.
This material may crystallize at storage temperatures
below 15°c (50°F). Before using, melt crystals and mix
material by warming drum to 30o-60oc (86°-140°F) and
rolling the drum. When mixing, avoid inclusion of moist air.
storage Temperature: 77°F (25°c) / 122°F (50°c)
shelf Life: 12 months @ 77°F (25°c)
8. Exposure Controls/Personal Protection
eye Protection:
Liquid chemical goggles or full face screen.
contact lenses should not be worn.
skin Protection: Rubber Gloves, aprons and other
protective clothing as required to prevent contact. Remove
any contaminated clothing and wash before use. Routinely
wash hands, arms and face with soap and water after
handling. Do not smoke or eat until hands and face have
been washed.
Ventilation and Respiratory Protection: Ventilate as required
to maintain diisocyanate concentrations below 0.005 ppm.
At room temperature general mechanical ventilation is
adequate, at elevated temperatures additional ventilation
may be required. An organic vapor respirator may be used
for short periods as supplemental protection at levels below
the exposure level. At exposure levels above exposure limits
a supplied air respirator is required due to the poor warning
properties of this product. other: safety showers and eye
wash stations should be available.

This material reacts slowly with water and is not expected to
accumulate in the environment.
13.Disposal Considerations
Waste Disposal Method: If discarded in its purchased form,
this product is not hazardous waste either by listing or by
characteristic. However, processing, use or contamination of
this product may change its hazardous waste status. Under
RcRA, it is the responsibility of the product user to deter-
mine, at the time of disposal, whether a material is a hazard-
ous waste. state and local disposal regulations may differ
from federal disposal regulations. Dispose in accordance with
all federal, state, and local waste disposal laws and regula-
tions. Incineration is the preferred method.
