Chemical resistance
EXPANCEL DU and WU
XXX No reason to believe that unfavourable
effects on EXPANCEL will appear not even after
rather long periods. XX Special care must be
taken, especially when used in contact with
EXPANCEL for prolonged periods or at elevated
temperature. X Contact with EXPANCEL must
generally be avoided. severe discoloration
moderate discoloration

Chemical resistance
EXPANCEL DE
XXX No reason to believe that unfavourable
effects on EXPANCEL DE will appear, not even
during rather long periods (volume loss less
than 10 ). XX Special care must be taken,
especially when used in contact with EXPANCEL DE
for prolonged periods or at elevated temperature
(volume loss between 10-50 ). X Contact with
EXPANCEL DE must generally be avoided (volume
loss more than 50 ). Severe discoloration Mo
derate discoloration
