Benefits of technology

[0036]The presence of component B) in the aqueous compositions of the invention acts as an effective brightener in electroplating, electrowinning, and electroforming baths. Component B) is a low foaming surfactant and is qu

Problems solved by technology

However, the use of wetting and/or defoaming agents in natural rubber latex compositions has not been uniformly satisfactory, since a number of criteria must be met, e.g. the wetting and/or defoaming agent must not destabilize the

example 1

Preparation of the Reaction Product of Decyl Alcohol.4EO and Epichlorhydrin

[0225]About 150 grams of decyl alcohol ethoxylated with an average of 4 moles of ethylene oxide (0.45 OH equivalents) were mixed with 385 grams of toluene and 54 grams of 50% aq. NaOH (0.675 equivalents). The water was removed by azeotropic distillation and when a moisture level of less than 0.8% was reached, about 46 grams (0.51 equivalents) of epichlorhydrin were slowly added. This mixture was allowed to react at 100° to 110° C. for 24 hours. An aliquot of this mixture was removed and filtered to remove the NaCl and vacuum stripped to remove the toluene to give an amber, easily pourable liquid product that was dispersible in water.

example 2

[0226]A natural rubber latex composition is prepared by mixing together the following components:

[0227]A) a natural rubber latex which is a milky white liquid emulsion obtained from the cells of the Para rubber tree (Hevea brasiliensis); and

[0228]B) 0.25% by weight of the reaction product of Example 1.

example 3

Preparation of the Reaction Product of Octyl Alcohol.4EO and Epichlorohydrin

[0229]About 200.0 gm (0.654 hydroxyl equivs.) of octyl alcohol ethoxylated with an average of 4 moles of ethylene oxide was mixed with 400 gm toluene and 78.4 gm (0.98 equivs.) of 50% NaOH. Water was removed by azeotropic distillation until the level was below 0.8%. The mixture was cooled to 80° C. and 67.2 gm (0.72 moles) of epichlorohydrin was added over 45 mins. The mixture was stirred for 24 hrs at 110° C. until the epoxy titration showed no epoxide left. The material was cooled, filtered and the toluene was removed by vacuum distillation leaving a dark brown low viscosity liquid.

Abstract

Coatings for metal containers, metalworking lubricant compositions, compositions for electroplating and electrowinning, and latex compositions comprising a base-catalyzed reaction product of (a) at least one compound of formula I
R1(X)3  (I)
wherein each X group is a halogen atom or one X group is a halogen atom and two X groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the R1 group to form an epoxy group, and R1 is an alkanetriyl group containing from 3 to 10 carbon atoms; and (b) at least one compound having the formula II
R2X(AO)nY  (II)
wherein R2 is a substituted or unsubstituted, saturated or unsaturated, organic group having from 1 to 36 carbon atoms; X is —O—, —S—, or —NR3— where R3 is hydrogen or a C1-C18 alkyl group; each AO group is independently an ethyleneoxy, 1,2-propyleneoxy, or 1,2-butyleneoxy group, n is a number from 0 to 200; and Y is hydrogen, or Y can be a mercapto group or an amino group or a C1-C6 alkylamino group in place of a terminal —OH group, provided that when Y is mercapto or an amino group, or a C1-C6 alkylamino group, n is at least 1; wherein the mole ratio of component a) to b) is from 0.1:1 to 5:1; are described.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority, under 35 U.S.C. §119(e), of U.S. Provisional Patent Application Nos. 60 / 423,118, 60 / 424,249, 60 / 430,485, and 60 / 434,477, filed on Nov. 1, 2002, Nov. 6, 2002, Dec. 3, 2002 and Dec. 18, 2002, respectively, the entire contents of each of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]One of the last stages in the manufacture of aluminum cans and other metal containers such as ferrous metal containers is the application of one or more finishing coatings for decorative purposes and / or identification.[0003]Such finishing coatings include acrylic paints, phenolic coatings which are used for baked can coatings, bitumen paints which are used for aluminum paints, coumarone-indene paints which are used to make aluminum paints, lacquers (which is a term also applied to the baking finish applied to the interior of food and beverage cans), and enamels.[0004]Lubricating oils are fluids whose...
