Water-based paints action

The fact that very low concentrations of polymer give highly viscous solutions is exploited commercially in a number of applications. The thickening action of polymers is often necessary for water-based substances, such as foods, toothpastes, or emulsion paints, but examples also occur of the use of polymers to thicken solvent-based products, such as paint stripper. 

The application of paints to metallic objects for corrosion control has been known for a long time. The mechanism of protection by paint films was viewed as a source of insulation of the metal from the corrosive environment such as oxygen and water and inhibiting the cathodic reaction. The idea of protective action of paint films by providing insulation of the metal from oxygen and water was questioned, based on the data given in the literature. 

Hexahydro-1,3,5-triethyl-s-triazine. Industrial preservative, prevents bacterial action in cutting oils, synthetic rubber latex, starch based adhesives, latex paint and aqueous slurries. It is soluble in acetone, ethyl alcohol, ether and water, moderately soluble in hydrocarbon solvents. 

USE As water-soluble lubricants for rubber molds, textile fibers, and metal-forming operations. In food and food packaging. In hair prepns, in cosmetics in general. Pharmaceutic aid (ointment and suppository base). As a stationary phase in gas chromatography. Also in water paints, paper coatings, polishes and in the ceramics industry. Caution Solvent action on some plasticsl... 

So many industrial and commercial uses have been found for Pb that it is difficult to list them all. The main uses of Pb which are most relevant to environmental contamination and human exposure are lead-based indoor paints, lead water pipes, lead solder in cans for storing food, and leaded gasoline additives these have either since been banned or are in the process of being banned. Action is also being taken with respect to lead glazes on pottery and ceramics, lead in...
