Question:

how does chemistry help paint?

how can chemistry assist making paint better? 10 points.

Answer:

Paint is a dispersion of colored insoluble pigments in a resin binder motor vehicle (no rely if waterbased, oil based or solvent based). The so-referred to as solvents for the paint are in many situations greater suitable referred to as thinners, being greater often than not to change the viscosity of the paint. Pigments do no longer dissolve and can be prompted to fall out of suspension via over use of thinners or the incorrect thinners. The finely divided paticles of pigment start to form agglomerates which drop out of suspension, it relatively is named flocculation. in assessment Dyes do totally dissolve in the solvent. Dyes are used in woodstains.
A paint is composed of pigments, vehicle, binders, resins (liquid) and various additives. The pigments give the paint color; the vehicle or solvent carries the components; binders keep it stable in solution and help it dry; and additives serve as everything from fillers to anti-fungicidal agents. Hundreds of different pigments, both natural and synthetic exist. White paint mostly uses TiO2 as a pigment. Chemists search for better solvents, to reduce health problems; better binders, to make the paint coating strong and stable; better pigments to keep their colour with age and light.
