  • Example I One preferred formula for the wax composition of the present invention is set forth in Example I as follows :
  • composition useful in the present invention resulting in a product with a solids content of 18.4-19.4 , specific gravity of 0.890 to 0.910, flash point of 126 'F and viscosity at 70 "F from 1400 - 1600 cps RPM 60/Spindle #4 is as follows :
  • Corrosion Inhibitor - LUBEROS RP 3118 1.0 Figure 3 shows a comparison of steel plates subjected to the same selected humidity for 140 hours with 3 (a) showing a clean, bare steel panel no wax control, 3 (b) showing a clean, bare steel including application of wax according to the composition of Example 3 with no corrosion inhibitor, and 3 ® showing a clean, bare steel plate including application of wax including a corrosion inhibitor according to the formula set forth in Examples 4 and 5 using high purity aluminum oxide having a mean particle size of less than 300 nanometers and preferably 200 to 250 nanometers or less.
  • the cleaning and polishing wax composition of the present invention imparts a good degree of hydrophobicity to the waxed surface which traditionally consists of a metal, glass, plastic, or painted surface.
  • water was used to wet the surface of metal panels giving results of very low contact angles of from 10 to 15 degrees.
  • the contact angles increase providing an indicator measuring the balling up of water droplets on the surface. Angles greater than 90 degrees are truly non-wetting.
  • Figure 4 Five panels were prepared by rinsing in mineral oil to remove any coatings. Five drops of the cleaning and polishing wax were applied to four of the panels and left to cure overnight. Figure 4 shows that the contact angle of the control reference panel to be about 88 degrees. After 1 washing the contact angle of the waxed panel was about 112 degrees, after 5 washes about 114 degrees, after 10 washes about 106 degrees, and after 15 washes about 108 degrees indicating continued protection even after 15 washes.

Abstract

Selon l'invention, une composition de cire d'émulsion inverse composée de cires naturelles et synthétiques, d'agents de surface, d'agents de suspension, de particules d'oxyde d'aluminium de pureté élevée possédant un diamètre moyen de particules inférieur à 300 nanomètres, généralement compris entre 0,20 et 0,25 microns (200-250 nanomètres), ne contient pas d'oxyde de magnésium et est aggloméré librement avec un solvant hydrocarboné aliphatique, ce qui produit une cire possédant des propriétés de nettoyage et garantissant une surface de forte brillance en une seule application.
