What are the three substances that generally make up paint? describe each part. what are polymers? what is a scanning electron microscope? what are its advantages? what is the pdq? what is it used for?

The three parts that make up paint are pigments, binders and solvents. Pigments consist generally of organic and non-organic compounds and materials that are added to paint to produce a particular color. Binders are substances that provide support or structure for the pigment and solvents to work. Solvents work to dissolve or disperse these substances into liquid form.
Polymers are a group of atoms that form in repetitious patterns The scanning electron microscope is a microscope that works by shooting beams of electrons at the slide and recording the emissions of the electrons. One advantage is that it has much better magnification than other microscopes
