Lead antimonate [13510-89-9] (Naples yellow), Pb2(Sb0 2> mol wt 993.07, d = 6.58g/cm, is an orange-yeUow powder that is insoluble in water and dilute acids, but very slightly soluble in hydrochloric acid. Lead antimonates are modifiers for ferroelectric lead titanates, pigments in oil-base paints, and colorants for glasses and glazes (see Colorants for ceramics). They are made by the reaction of lead nitrate and potassium antimonate solutions, followed by concentration and crystallization. 

The main use of these clays is to control, or adjust, viscosity in nonaqueous systems. Organoclays can be dispersed in nonaqueous fluids to modify the viscosity of the fluid so that the fluid exhibits non-Newtonian thixotropic behavior. Important segments of this area are drilling fluids, greases (79,80), lubricants, and oil-based paints. The most used commercial products in this area are dimethyl di (hydrogen a ted tallow) alkylammonium chloride [61789-80-8] dimethyl (hydrogen a ted tallow)aLkylbenzylammonium chloride [61789-72-8] and methyldi(hydrogenated tallow)aLkylbenzylammonium chloride [68391-01-5]. 

Eor water-based alkyd paints, greater (0.2% cobalt on a resin basis) concentrations of drier are required than for other systems because the reaction of the drier with water decreases the activity of the catalyst. The cobalt content of oil-based paint formulations is usually 0.01—0.05% cobalt. Although the concentration of cobalt in the formulations is small, the large volume of paints, inks, and varnishes constitute a significant use for cobalt chemicals.

Paint applied to a suitably prepared zinc coating will last longer than would be the case if it were applied direct to iron or steel, and the need for repainting thus becomes less frequent. With hot-dip galvanised or zinc-plated coatings, however, it is necessary either to use special primers or to prepare the surface before painting. This is primarily because most oil-based paints react with the unprepared zinc surface to form zinc soaps resulting in poor adhesion. 

If an elastic or insufficiently hard primer or paint has been applied under a less elastic top coat, or if the first coat (or set of coats) of oil-base paint has been second-coated before it is completely dry, not only will the paintwork remain soft for an unduly fong period, but cracking will also follow, as the upper layer cannot follow the movement. If the last coat is very thick this fault will frequently manifest itself in the form of alligatoring, i.e. the formation of cracks which do not penetrate all the films down to the substrate, and which may be present in the top layer only.

That winter the whole inside of my parents house was painted with an oil-based paint. After that my tendons swelled, I had to wear a neck brace and I couldn t even feed myself, but we didn t realize there was a connection between the chemical exposure and my health. The tendons in my eyes were so swollen I could hardly see. It was terrifying and traumatic for me. For three years I was in bed, couldn t see anybody or do anything. It was all I could do to try to sit for a few minutes at a time. I missed my friends from college, missed school and missed my active life. I wasn t in touch with my feelings at the time. I had to stay above them or I never would have survived. 

I started painting about 1980. We did a lot of architectural finishes, finishes with cyanide in them, things like that. Sometimes we burned old paint to remove it. When you burn paint it changes the composition. Not even the manufacturer can tell you what the composition will be once you heat it. We used paint thinner to get oil-based paint off our skin. That just zaps into the bloodstream. 

It is known that fluorinated HDPE containers are highly suitable for the packaging of numerous other products such as adhesive systems, oil-based paints, polishes, hand cleaners, and hydrocarbon solvents.12... 

During the drying process, only water vaporizes.- With oil-based paints, naphtha or mineral spirits vaporize during drying. (Latex paints don t pollute the atmosphere.)...

Products with a high percentage of solvents, such as oil-based paints, paint removers, fuels, lighter fluids, furniture polishes, and some pesticides can cause potentially fatal pneumonia if aspirated into the lungs as a result of accidental ingestion. If used in an unventilated space, they can also cause symptoms of acute intoxication, including dizziness, nausea, and in some cases nerve damage or other effects. 

Storage of fats and oils leads to rancidity, a largely oxidative deterioration that causes development of unpleasant tastes, odors, and toxic compounds.239 Similar chemical changes account for the "drying" of oil-based paints and varnishes. These reactions occur... 

Lyophilic stabilisation is particularly important in non-aqueous systems115, e.g. oil-based paints, and in systems of very high particle concentration where electrostatic stabilisation is of limited effectiveness. It is also essential in biological systems, e.g. blood, where the... 

All the above formulations have been investigated and evaluated on perforated and unperforated Celotex fiberboard. Results demonstrate that a satisfactorily formulated intumescent water- or oil-base paint is the best type of paint to apply to acoustical fiber board to secure optimum fire or flame resistance. These paints, by their intumescent nature, tend to close the openings in the acoustical fiber board and insulate the basic fiber under the coating.
