Composition Phthalic acid ester of higher molecular aliphatic alcohols. EDENOL LFW 101 is a secondary plasticizer and its properties are similar to those of the well known fatty acid esters.

EDENOL LFW 101 is highly recommended for sanding primers not containing zinc stearate, which have to be coated with acid curing lacquers. It is necessary to use EDENOL LFW 101 as the sole plasticizer in order to obtain optimum sanding properties. It is very compatible with ester and alcohol soluble nitrocellulose as well as with alkyd-maleic and urea resins. Strongly polar products such as ketone-aldehyde resins, polyvinyl acetate, alcohol soluble resins etc. are not very compatible. With combinations of nitrocellulose and urea resin containing acid catalyst, it has to be noted that compatibility with the amino resin is reduced as the reaction proceeds, which could result in migration of EDENOL LFW 101 or cloudiness of the film. It is advisable to run preliminary tests in order to determine the optimum concentration of EDENOL LFW 101. With a lacquer film comprising equal parts of nitrocellulose and EDENOL LFW 101 the migration temperature is approx. 110 - 120 °C. This range should not show any disadvantages during actual processing, neither should it have any effect on value of the coated item. The plasticizing properties of EDENOL LFW 101 are slightly inferior to those of fatty acid esters. As the product is not a primary plasticizer and because of its higher setting point (EDENOL LFW 101 shows a buttery consistency at room temperature) the effect obtained with EDENOL LFW 101 lies between that of plasticized resins and liquid secondary plasticizers. Therefore, it is advisable to always include a primary plasticizer for use in nitrocellulose lacquers, the amount of which depends both on formula and required film properties. The use of plasticizing resins such as alkyd resins should also be considered where EDENOL LFW 101 is used as the sole plasticizer, for example in sanding primers free from zinc stearate. Secondary plasticizer for wood lacquers, paper varnishes and strippable coatings to reduce drying time and to improve sandability. Solidifies below 25°C, 100% active substance. Similar properties to those of the well known fatty acid esters. Incompatible with dimethyl glycol phthalate and plasticized urea resins. Used in nitrocellulose clear varnishes for the coating of wood and paper, recommended for sanding primers not containing zinc stearate, which have to be coated with acid curing lacquers. Used as the sole plasticizer in order to obtain optimum sanding properties. Compatible with ester and alcohol soluble nitrocellulose as well as with alkyd-maleic and urea resins. Strongly polar products such as ketone-aldehyde resins, polyvinyl acetate, alcohol soluble resins etc. are not very compatible. With combinations of nitrocellulose and urea resin containing acid catalyst, it has to be noted that compatibility with the amino resin is reduced as the reaction proceeds, which could result in migration of this product or cloudiness of the film. With a lacquer film comprising equal parts of nitrocellulose and this additive the migration temperature is approx. 110 - 120 °C.
