molecular weight polyvinyl alcohol (PVOH). Using the
exclusive batch process which has advantages over other manufacturing methods,allows more

it is good practice to test the material. As such, we advise that material stored for 12
months or more after delivery should be tested before use.
SOLUTION PREPARATION:
The Hot Method is the most efficient if dispersion / wetting of the powder is an issue. It is
either added slowly to water at more 90°C or to water at room temperature and then heated to
more 90°C, with good agitation. It will disperse and on cooling will go smoothly into
solution without lump formation.
