1. Usage (safety goggles
and rubber gloves recommended)
When handling large volumes of powder products,
powder dust may scatter. When handling these products, be sure to
wear safety goggles, rubber gloves, and a dust-protective mask.
If the powder product accidentally gets into your eye, do not rub
your eye. Rinse with a steady flow of water for at least 15 minutes,
and then consult a medical specialist.
If the powder product adheres to your face, hands and feet, or any
other exposed skin, wash it away with soap.
If the powder product spills onto the floor or ground, immediately
wipe it up with a cloth or paper. Spilled powder readily absorbs
moisture and becomes extremely slippery, so after wiping, flush
the area with a large volume of water. Scattering sand is also effective
as an emergency measure.
For more information, please see the " Material Safety Data Sheet"
supplied with the product concerned.
2. Safe storage (product
products come in paper bags with inner plastic
bags, and emulsion/liquid products come in metal cans or bulk
containers. As they are all packages designed for indoor storage,
please store the product in a well-ventilated room.
The shelf life of powder products is
year, and that of emulsion/liquid
products is three to six months. It may differ slightly depending
on storage conditions, but please use the product within the specified
The storage stability of dissolved products is extremely low.
Although it differs among anionic, nonionic, and cationic products,
please try to use them as quickly as possible. Note also that
performance degradation occurs quicker particularly in cationic
3. Corrosiveness (products
and liquid solutions)
Powder products are non-corrosive toward metals in general. However,
emulsion/liquid products are highly corrosive, so avoid contact
with steel, aluminum, and other general metals.
On the other hand, dissolved products are generally corrosive
when their electric conductivity increases. Cationic solutions
particularly become corrosive because they have lower pH levels
(they are more acidic).
Based on the above points, recommended materials for equipment
that come into contact with the emulsion/liquid solution, such
as the dissolving unit, dissolver, mixer, piping, and pump, include
hard vinyl chloride
resin, FRP and other plastics, and rust-resistant
When using a steel tank, apply an anti-corrosive coat (coal tar
epoxy, etc.) to the
of the tank.
MT Aquapolymer, Inc. has conducted numerous skin
tests and animal experiments to verify the safety of
Acrylamide (monomer), the raw material used in polyacrylamide
polymer flocculant, has relatively high toxicity, and was registered
a "deleterious substance" in Japan in 1974. The safety
of Acrylamide (monomer)-based polyacrylamide was confirmed in
a test of the
a two-year continuous administration experiment
on dogs and rats.
Various other experiments have also been conducted showing that
polyacrylamide is pharmaceutically "chemically

time, be sure to wear safety goggles, rubber gloves, and other
protective gear. Also be sure to wash your face and hands after
