Frequently Asked Questions
GENERAL INFORMATION
PVOH®9913 is a fully hydrolyzed medium molecular weight polyvinyl alcohol (PVOH). Using our exclusive batch process which has advantages over other manufacturing methods,allows more efficient control over the degree of hydrolysis and particle size of the product.
USES
PVOH®9913 achieves the best performance in textile, paper, molding, and adhesive industry.
SOLUTION PREPARATION:
The Hot Method is the most
efficient if
dispersion / wetting of
the powder
is
an issue. The
PVOH®9913 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. The PVOH®9913
will
disperse
and on cooling
will go smoothly into
solution
without
lump formation.
STORAGE AND SHIPPING:

Ingress of moisture should be avoided to maintain product quality. 2.As supplied, PVOH®9913 should remain fit for use for 12 months from the date of delivery. Beyond that date, the material may still be fit for use, but we would advise that it is good practice to test the material. or more after delivery should be tested before use.
