4. Some types of pigment control gloss.
BINDER:
1. Holds pigment together when in dry film form.
2. Acts as a 'vehicle' that carries pigment when applied.
3. Type determines durability of end product.
4. Provides adhesion to the surface to which it is applied.
THINNER:
1. Combines with pigment and binder to control consistency.
2. Plays a roll in film drying.
ADDITIVES:
1. Help control application properties (brush, roll, spray, etc.)
2. Help some product formulations dry
3. Aid in pigment dispersion in manufacturing.
4. Aid in pigment dispersion when adding liquid colorant.
