Wood wax (aqueous) These are unpigmented, colorless formulations which are also waterbased and employed mainly for wood panel polishes. Apart from an increase in shine, sensitivity to water can be improved. Guide formulation Licowax KLE Emulsion, 12 % 50.00 Mowilith ® DM 772 conc. Tributoxyethyl phosphate 48.40 (wetting and levelling agent) 1.00 Licowet ® F 3, 1% solution 0.50 Saniprot ®+ 98-70 0.10 Parts by weight 100.00 Licowax KLE Emulsion, 15 % 51.00 Water 22.50 Mowilith ® DM 772, 46 % 26.00 Licowet F 3, 1% solution 0.50 Parts by weight 100.00 26 Improving sandability For furniture lacquers, the addition of Licowax C micropowder to lacquers based on polyurethane, acid-curing lacquers and nitrocellulose lacquers has proved successful in improving the sandability of primers. So that the wax can function optimally it should first be dispersed in a suitable solvent in a bead mill. The following formulation is possible: Licowax C micropowder 10.00 Xylene 45.00 Butyl acetate 45.00 Parts by weight 100.00 This dispersion can also be prepared in a sand or ball mill. Ceridust 3910 is easier to admix. It is dispersed direct in the paint by means of a stirrer. With two-pack polyurethane finishes it is preferable to incorporate Licowax PE 520 as a solvent-containing dispersion in the finish. Guide formulation for polyurethane sanding primer Desmophen solution (component A) Desmophen ®+ 1300 75 % solution in xylene 32.0 Nitrocellulose chips E 510 1.5 Ethyl acetate 9.2 Butyl acetate 9.2 Methoxypropyl acetate 9.2 Xylol Licowax PE 520 1.9 10 % dispersion in Xylol 12.0 Parts by weight 75.0 Desmodur solution (component B) Desmodur ®+ IL 14.2 Desmodur ®+ L 75 9.4 Xylol 1.4 Parts by weight 25.0 Mixing ratio component A : component B 3:1 Binder content approx. 40 % Efflux time at 23 °C and DIN cup 4 mm, DIN 53 211 approx. 20 sec. Drying time at room temperature 150 µm thick wet film approx. 35 min
Influencing the rheological properties of paints Licowax PED 521 and Licowax PED 522 have proved very successful in preventing alkyd resin paints from sagging and running. 20 parts by weight Licowax PED 521 or Licowax PED 522 are dissolved in 80 parts by weight xylene at 80 °C to 90 °C and the solution is cooled to room temperature with slight stirring. The resultant dispersion is then incorporated in the paint. The wax preparation must be added at the very beginning of the manufacturing process. 0.25 % to 1 % of the wax preparation, relative to the binder, is sufficient to produce the desired effect. Making paints water-repellent Ceridust 9615 A is suitable for making protective wood finishes and protective wood stains water-repellent. 2 % to 6 % of the product incorporated in the finished paint give the film good water repellency at the initial drying stage. The finish was applied to pine and was weathered outdoors for 3 years. Independent of improved water repellency, the wax-containing finish decomposed significantly less than the wax-free finish. Assessment of water repellency after 1 1 2 3 hour year years years Without wax With 3.5 % Ceridust 3 3 4 4 2 2 2 2 Assessment: 1 = no dissolving 2 = trace of dissolving 3 = slight dissolving 4 = some dissolving 5 = noticeable dissolving Can coatings Improved slip behaviour and enhanced scratch resistance in can coatings can be achieved by using PTEE containing waxes such as Ceridust 9610 F, Ceridust 9630 F or Ceridust 3920 F. These micronized waxes can be processed directly into the lacquer. Guide formulation Duroftal ®+ VPE 6104 68.50 Vestanat ®+ B 1370 (60 % in XBAC) 7.00 Polysolvan ®+ O 12.05 Solventnaphta 180/210 12.05 Ceridust 3920 F 0.40 Parts by weight 100.00 The components shall be mixed and well homogenized in the above described order by using a dissolver. For this application, a wax dosage of 0.5-1 % has proved to be advantageous. Coil coatings A positive effect on slip behaviour and scratch resistance can be achieved by using PTFE-containing waxes in coil coatings. Especially recommended for this application are the following Ceridust grades: > Ceridust 9610 F > Ceridust 9630 F > Ceridust 3920 F > TP Ceridust 3921 F > Ceridust 9325 F > TP Ceridust 9322 F Excellent results can be achieved by using 0.5 to 1.0 % wax.
