Storage Under normal storage conditions within the range 5 – 25 °C, the product
will be stable for at least 24 months. Storage outside the above speci-
fied temperature range for long periods may adversely affect the
product over a long period and should thus be avoided, if possible.
It is recommended that stock solutions at 0.25 – 0.5 % are prepared
regularly and for maximum effect such solutions should be used within
5 days. Beyond this period some loss in efficiency of the product may
occur.
Shipping & Handling Effects of low temperature on dissolution – at low water temperatures,
<5 ° Celsius, the dissolution of this product will be adversely affected to
the extent that longer dissolution times will be required.
As with all cationic polyelectrolytes the product exhibits toxicity towards
fish. It is important that precautions are taken where the product may
come into direct contact with fresh water courses, streams and rivers.
Corrosion towards most standard materials of construction is very low.
Stainless steel, fibreglass, polyethylene, polypropylene and rubberised
surfaces are recommended. In some cases aluminium surfaces can be
adversely affected.
Packaging details are available on request from your local sales
representative.
Very slippery when wet. Please refer to the MSDS for methods of
removing the polymer.
Technical Service Account managers and field service technicians are available to give
advice and assistance in the running of laboratory tests and machine
trials to select the correct product and determine the best application
conditions.
