Question-
Give Reason why wall paint are always in liquid form.
Answer-
Paint has three componenets, pigment, binder and solvent.
Pigment is colour chemical substance in paint.
Pigments are solids, so we could not use them to paint by themselves. It is difficult to apply pigments to the surface directly.
They will not spread evenly and will not stict to the surface.Hence binder is mixed with pigment in order to glue make we get thick substance which is difficult to spread. Hence a solvent in liquid form is used to dissolve the pigment andthe pigment particles to glue together and also to them stick to surface.
After mixing binder to thewe get thick substance which is difficult to spread. Hence a solvent in liquid form is used to dissolve the pigment andthe pigment particles to glue together and also to them stick to surface. After mixing binder to the pigment,we get thick substance which is difficult to spread. Hence a solvent in liquid form is used to dissolve the pigment and binder
