What is PAINT MADE OF?

Question

I am doing a science project on how pH differs in differnt types of paint. I need to know though, what paint is made of.

Answer 1

Oil paint and Linseed oil.

The binder of this technique is linseed oil. Now, what is the main characteristic of linseed oil by which we can understand it's "logic"? Unlike other vegetable oils such as canola or olive oil, linseed oil reacts with oxygen (a process called oxidation), to slowly go from liquid to gel to a tough solid form, therefore we refer to it as siccative oil because it solidifies through oxidation. Linseed oil is not the only siccative oil and therefore is not the only oil we could use, poppy seed, safflower or nut oil are semi-siccative oils, but, generally, we avoid using them as our "main" grinding oil because they will to dry slower and form less flexible paint film than linseed. Another important aspect besides the fact that linseed oil oxidizes rather than dries is that this oxidation doesn't stop when the paint is dry, but continues on for years after the painting has been painted, varnished and sold. So, the second important aspect of oil paint is that it is a dynamic technique in this respect that it still continues to transform (i.e. react, oxidize) when the painting has long been finished.

Acrylic paint

The binder of acrylic paints is acrylic polymer emulsion. Unlike siccative oil that oxidize, this emulsion of plastic resins dries by evaporation of the water and solvents it contains to form a tough & flexible film. It can be purchased as gel or gloss medium, modeling paste and so on, each is acrylic polymer emulsion, but they have been added something else to make it mat or glossy, thick or liquid. One thing you have to pay attention is whether these mediums are designed to be opaque or transparent. Some acrylic mediums have been added either fillers or white pigments which makes them opaque, they can be used when an opaque paint is desired but attempting to glaze with such mediums would certainly be frustrating, if not impossible.

Gouache and watercolor

The binder for gouache and watercolor is gum arabic. which naturally comes from acacia trees. To make your watercolor we again recommend you to use the dispersions of pigments and it is most important in that technique. By adding drops of dispersions in the solution, you will instantly obtain transparent watercolor. To get an opaque gouache, simply mix either talc, zinc white or china clay into a paste using the same solution and add your dispersions or pigments.

Answer 2

All paint can be used on wood. You got to sand the surface smooth first, dust it off and then put on a primer first and let that dry overnight. An alkyd primer(oil based) is better than latex primer(water based) because what happens when wood gets wet with water - it swells. The water based paint will dry with the now "swollen wood". If you rub your hand over the dried primer, it would feel very rough like sandpaper. Putting an oil based primer on the wood - wood does not soak in the oil the same way as it does the water, so it does not swell as much. End result will be a smoother finish when dry the next day. Grab some 120 sandpaper and go over the primer lightly until it feels silky smooth and still not sand thru the paint. Blow off the dust. Any nail holes and cracks should be filled. Use paintable silicone. Give that an hour to dry(especially in the cases where it is a crack 1/4" or wider.) Otherwise 15 minutes. Now the paint finish of your choice Latex or Oil. Give it a coat. Wait overnight - give it a very light sanding to knock off the flies or other debris and another coat. Let dry for another day. Done. Lead has been taken out of paint now a days. So don't use some paint that has been there for 10 years or more. FYI.....I described this all while I am using a brush to do the job. Use the right kind of brush makes the job a breeze. For oil paint use a natural bristle brush(in this case I would pick a 2 1/2" sash brush(has angle cut bristles) Wash out brush in paint thinner or if it is going to be used the next day wrap the brush in saran rap(or plastic)keeping the bristles flat and put someplace out of the sun and heat. For latex paint use a polyester brush(especially the ones with the white tips). They are finer and more like natural bristle. Either wash the brush out very well with water(from the waterhose)when done or it to can be wrapped in plastic for an overnighter. Do NOT mix up the brushes. Polyester does not work very well in oils, neither does natural bristle in latex. Painting with a brush is like using either a fine pen to do calligraphy or using a thick wax crayon to do the same. I don't like to work any harder than I have to. Don't need the most expensive, a mid priced brush will do you for several houses after the crib. Spray paint is mainly solvents(very little paint) Comparison - take a quart of paint and throw in a gallon of thinner(water). That is about the same consistency. Don't put it on heavily, otherwise it runs. Brush it on a little on the dry side. The next coat will get the misses. Or the next. Disassemble as much as possible to make the painting easy. Turn on the tunes, coffee in one hand and do er'

Answer 3

you can go to www.doverpublications.com and get a book called The painter's methods and materials. Everything you need to know about paint and more

Answer 4

There are different kinds of paint, some are water based some are oil based. The materials put in these bases for color, thickness, resilience, vary also.

Answer 5

There are many different bases and pigments for paint.
The base carries the pigment, which is the colorant.
The base gives the color the ability to spred over the media evenly, and a certain look, feel, and durability.

The pigments are the tough part. You need so many different materials from all over the world.

Answer 6

Lead and some are acid based paints.

Answer 7

I have found two articles. The second one is a bit whacky but maybe worth a look!

Answer 8

it depends on the type of paint. there are three main types:

Oil: pigment mixed in with drying oils (not water soluble)
Acrlyic: pigment mixed with a polymer emulsion (water soluble)
Watercolor: pigment mixed with water (water soluble)
