Safe handling
1. Compounding agent and The common fillers and facilities for commodity rubber can be used for
facility DAI-EL. The mixing mill needs to be cooled. Finely divided metallic powder or
filler, such as aluminum and magnesium, or amine compounds of more than
10% should not be used as compounding agents for DAI-EL because such
materials are known to decompose vigorously at moderately elevated
temperature.

2. Storage and remixing Store the compound in a tightly closed package in a cool and dry place.
Another milling before use is recommended when the compound is left for
more than three days. Too tight a nip between the rolls in the mixing mill may
cause scorching. Be sure to cool the rolls well whenever the compound is
milled with tight nip.

3. Molding / Curing The work area should be adequately ventilated at all times because a small
amount of toxic gases (e. g. HF, acetone, methanol, acetaldehyde, methyl
iodide and carbon monoxide) may be evolved during curing.

4. Material handling A slight amount of hydrogen fluoride vapor may be produced during use at
high temperatures (above 200°C). The room should be well ventilated.
Do not smoke in the work areas as harmful vapors may be inhaled when
cigarettes are exposed to the powder of DAI-EL. After handling the powder of
DAI-EL, knock off any dust from your hair or clothing and wash your face and
hands thoroughly before smoking.

5. Disposal Do not incinerate DAI-EL as this can produce harmful vapors. Disposal should
be done in accordance with local laws and regulations.

• Read the "Material Safety Data Sheet" before use.
