Noel's Question
Why are turpentine or thinner added to paint?
ANSWER
Oil paint, which turpentine or thinner would be added to, is made up, basically, of:-
-
Pigment - to give colour, bulk and opacity. Normally in powder form so you can imagine the difficulty in applying to a wall on its own. Note:- there are other powder ingredience's, but we won't go into them here.
-
Oil - to bind the particles of powdered pigment together. Just oil and pigment would make a heavy viscose material. Referred to as the vehicle - to transport the pigment from paint tin to wall. Note:- there are other oils used to give many different properties to paint.
Now this is where the thinners or turpentine comes in. The thinner added to this mixture creates a material that can be applied with a brush. The thinner or turpentine then evaporates leaving what we know as the paint film.
