| How Paint Ingredients
Affect Quality
Pigments
Provide
color or whiteness and hiding
- Top
quality paints have higher levels of high-hiding pigments
-
Top quality exterior paints have more durable pigments
that resist chalking and fading better
Binders
They "bind" the
pigment into a tough, continuous film and help the paint
adhere to the surface.
- Top
quality flat paints have a higher binder to pigment ratio.
-
Many top quality exterior latex paints are based on 100%
acrylic binders for maximum:
-
adhesion when wet for resistance to blistering and peeling
- resistance to mildew and dirt
- alkali resistance over fresh masonry
Liquids
Liquids
carry the pigment and binders. In oil-based and alkyd paints,
the liquid is a paint thinner. In latex paints, the liquid
is water.
- Top
quality paints have less liquid and more solids (pigment & binders).
Additives
Ingredients
used at low levels to provide key properties, such as:
- Mildew
Resistance (mildewcide), found in quality exterior paints.
- Better
Flow & Leveling
-
Splatter Resistance
