Abstract:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) ethoxylated phosphate esters, ions of aluminum, zirconium, iron, tin, and/or cerium, and (iii) a metal etching component gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses.
Abstract:
Aqueous-based functional products or corrosive products such as cleansers, household products, commercial products, and personal care products are thickened or viscosity-modified by the addition of at least a small, but effective, amount of at least one crystalline mixed metal hydroxide conforming substantially to the formulaLi.sub.m D.sub.d T(OH).sub.(m+2d+3+n.a) A.sub.a.sup.n.xH.sub.2 Owhere m is zero to one, D is a divalent metal, d is from zero to 4, T is a trivalent metal, A represents at least one anion or negative-valence radial of valence n, where n is 1 or more, (m+2d+3+n.a) is equal to or greater than 3, (m+d) is greater than zero, and xH.sub.2 O represents excess waters of hydration.
Abstract:
Novel monodispersed crystalline mixed metal layered hydroxide compounds of the general formula are prepared: Li.sub.m D.sub.d T(OH).sub.(m+2d+3+na) A.sub.a.sup.n, where m is an amount from zero to 1; D is a divalent metal; d is the amount of D ions of from zero to 4; T is a trivalent metal; A represents anions or negative-valence radicals of valence n; na is from zero to -3; (m+d) is greater than zero; and (m+2d+3+na) is equal to or greater than 3. The D metal is preferably Mg and the T metal is preferably Al. These compounds are useful as gelling agents which impart beneficial thixotropic properties to various fluids, such as drilling fluids, especially when employed along with fluid loss agents.
Abstract:
The invention relates to thickened fuctional fluids. The functional fluids can be used in hydraulic systems or as metalworking compositions to cool and lubricate surfaces which are in frictional contact during operations such as the turning, cutting, peeling, or grinding of metals.The functional fluid contains a diluent, a dialkyldithiophosphate, a compound which is a source of molybdate ion, a polyether nonionic surfactant, and an associative polyether thickener.
Abstract:
Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto and which melts within the range of about 30.degree.-100.degree. C. The composition comprises at least one neutral ester, and preferably a mixture of esters, prepared from polyalkylene glycols and saturated aliphatic alcohols having at least about 10 carbon atoms, and C.sub.12-25 aliphatic monocarboxylic acids and C.sub.4-20 aliphatic polycarboxylic acids. The preferred ester mixtures are prepared from polyethylene glycols, C.sub.14-20 predominantly straight chain alkanols, stearic acid and adipic, azelaic or sebacic acid. Optional ingredients include phosphorus acid salts and antioxidants. The composition may be applied in liquid form and solidifies on cooling to normal ambient and storage temperatures.
Abstract:
Improved internal combustion engine lubrication is obtained by the controlled rate of release of certain solid particles into circulating lubricating oil. Compositions are set forth comprising such solid particles combined with solid thermoplastic polymer having a controlled rate of dissolution in the lubricating oil. Also included are methods and apparatus wherein such solid particles are added to the engine lubricating oil, for example, which involve the filtering system for such oils.
