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.

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.
