A corrosion protection composition that is advantageously unobjectionable from a health risk point of view and not easily flammable, for the economic production of anticorrosion coatings on metal workpieces, in particular, workpieces made of cast iron or steel, for the period of their storage and transport until the workpieces are installed, is composed of a solution of a mineral wax mixture in a liquid monocarboxylic acid ester. The composition includes from about 5 to about 10 parts by weight of a mineral wax mixture which has a molecular weight ranging between about 400 and about 600, and from about 70 to about 85 parts by weight of at least one liquid monocarboxylic acid ester which has a boiling point above 340° C., and, optionally, additives such as antioxidants, antiozonants, antiaging agents, corrosion inhibitors, light stabilizers, and/or wetting agents. The corrosion protection composition, when heated, forms a clear, low-viscosity solution and, after being applied to the workpiece and cooled, forms a coating having viscous consistency which ranges from salve-like to pasty. The coatings are well suited to provide corrosion protection for, for example, piston rings or other sealing rings for internal-combustion engines.

The invention relates to a method for applying a protective coating to returnable glass containers comprising the steps of transporting the glass containers by means of a conveyor line, providing a supply of coating liquid, feeding the coating to a spray means positioned at a coating station of the conveyor line, applying the coating liquid onto the outside of the glass containers on the conveyor line by means of the spray means.

Method, apparatus and coating liquid for coating returnable glass containers

Modified polyethylene with an average molecular weight of 500 to 10,000 is disclosed. The polyethylene has one or more laterally bound group(s) of the formula --CONH(CH.sub.2).sub.n NR.sup.1 R.sup.2 wherein R 1 and R 2 are the same or different and represent a low molecular weight alkyl group with 1 to 4 carbon atoms and n is 2 or 3, or its salts with aliphatic carboxylic acids with 1 to 3 carbon atoms. The modified polyethylene is applied in the form of an aqueous dispersion, to glass surfaces, especially the external surfaces of glass containers. The modified polyethylene is suitable especially for so-called cold-end finishing. The protective layers obtained have very good smoothing values. The protective layers are resistant to the repeated action of hot, aqueous washing liquors and retain their smoothness. Glass containers, provided with the protective layer, can be labelled in the usual manner.

Use of modified polyethylene for finishing glass surfaces

A composition for use in recycled food and beverage containers is disclosed. A mixture of a strong sequestrant, a weak sequestrant, a polymer, an antiscalant and a surfactant is disclosed. Methods directed to using the composition are also disclosed. A composition that cleans and also reduces the defects present on the external surface of containers during a wash cycle is disclosed. The composition may or may not have metallic salts.

A composition for aesthetic improvement of food and beverage containers and methods thereof
