Bi-functional special plasticizer for lacquers.
Composition Phthalic acid ester of a special mixture of alcohols.
EDENOL® LFW 100 is a bi-functional plasticizer
which acts in nitrocellulose lacquers simultaneously
as a primary plasticizer and a fatty acid ester. This
means that the primary/secondary plasticizer
combination usually applied in nitrocellulose
formulations may be replaced by EDENOL® LFW
100.
The advantage is that the secondary plasticizer
cannot separate from the film compound, as it is
chemically linked to the primary plasticizer.
EDENOL® LFW 100 does not dissolve nitrocellulose
at room temperature. It is only at higher
temperatures (approx. 100 °C) that EDENOL® LFW
100 shows its gelatinizing properties for
nitrocellulose. Nevertheless, it may be classified as a
primary plasticizer, as its plasticizing effect is
approximately equal to that of a phthalic acid ester.
EDENOL® LFW 100 can be easily combined with
alkyd-maleic and urea resins, but not with highly
polar binders such as ketone-aldehyde resins.
Please note, however, that in nitrocellulose/urea
resin lacquers which contain acid catalysts, the
compatibility of EDENOL® LFW 100 decreases as
the cure of the amine resin advances. This can
result in a cloudy film and it is, therefore,
recommended to evaluate compatibility by initial
laboratory trials.

Application As the effect of EDENOL® LFW 100 on the drying
process is equivalent to that of a fatty acid ester, it is
particularly suitable for nitrocellulose wood and
furniture lacquers. It develops its positive properties
above all in thick film finishes where high demands
are made in respect of drying properties and
stackability.
Solvent release as well as the smoothness and
scratch resistance of the film surface may be further
improved by using it together with a secondary
plasticizer such as EDENOL® BS 20 N, allowing
these properties to be adjusted to meet all practical
requirements. The combination of EDENOL® LFW
100 with pure primary plasticizers does not produce
any advantages.
On the contrary, this may impair the typical
properties of the bi-functional EDENOL® LFW 100,
and thus adversely affect the drying process and the
stackability of the lacquer.
