摘要:
A process for thickening an organic liquid, particularly useful in the manufacturing of lubricant greases, comprises; mixing the liquid with a metal sulphonate and possibly a volatile organic solvent, and then heating and/or grinding the resulting mixture.
摘要:
A grease composition having excellent high temperature and multipurpose properties comprising a lubricating oil and an effective amount of a thickener which is a selected pyrrolidone compound.
摘要:
A lubricant gel is made from a poly(alkylene oxide) lubricant, a finely divided silica and a gel-strengthening amount of an ionic salt having a pH of 5.5-8.5 when in 0.1 M aqueous solution. The gel is useful in the inflation chamber of a pnemuatic tire to enable it to run safely in a deflated condition for which purpose the gel should have the required viscosity and mechanical stability.
摘要:
A new coating composition, coated article and method are disclosed herein dealing with the preparation of coated surfaces which are useful, for example, in glass molding wherein a relatively lubricious, abrasion resistant surface is desired under conditions of high operating temperatures. The coating composition in its most basic aspect involves a dispersion of an aluminum phosphate and a very fine particle size pigment material together with other materials including novel dispersion stabilizing ingredients and a special water dispersible resinous film-modifying agent.

摘要:
Disclosed are materials that possess both low adhesion and the ability to absorb water. The material passively absorbs water from the atmosphere and then expels this water upon impact with debris, to create a self-cleaning layer. The lubrication reduces friction and surface adhesion of the debris (such as an insect), which may then slide off the surface. The invention provides a material comprising a continuous matrix including a polymer having a low surface energy (less than 50 mJ/m2) and a plurality of inclusions, dispersed within the matrix, each comprising a hygroscopic material. The continuous matrix and the inclusions form a lubricating surface layer in the presence of humidity. The material optionally contains porous nanostructures that inject water back onto the surface after an impact, absorbing water under pressure and then releasing water when the pressure is removed. The material may be a coating or a surface, for example.
