The basic white pigments include zinc oxide, zinc sulfide, lithopone, and titanium dioxide. Most black pigments are composed of elemental carbon. Common red pigments include the minerals iron oxide, cadmium, and cuprous oxide and various synthetic organic pigments.
What are the raw materials for paint production?
Raw materials are divided into three major groups, namely, pigments (titanium dioxide, zinc oxide etc.), solvents (mineral turpentine) and resins and additives. Pigments are finely ground solids of different shades to give colour, durability, consistency and other properties to paint.

Should you PVA before painting?
Before painting the new plaster you will require a sealer to prime the surface. Contractors often worryingly think PVA will work as a sealer. Do not use PVA. This allows the initial coat to properly soak into the plaster aiding adhesion of the final coat.

What can PVA be used for in coatings?
Polyvinyl Alcohol (PVA) for Tablet Coating Applications. Purpose: Polyvinyl alcohol (PVA) is a well-established polymer for film coating. PVA is a synthetic, bio-compatible and toxicologically well characterized polymer. It is frequently used in pre-mixed coating formulations. Fixed combinations with additional ingredients are well established.

Which is the idealized formula for polyvinyl alcohol?
Poly (vinyl alcohol) ( PVOH, PVA, or PVAl) is a water – soluble synthetic polymer. It has the idealized formula [CH 2 CH (OH)] n. It is used in papermaking, textiles, and a variety of coatings. It is colourless (white) and odorless. It is sometimes supplied as beads or as solutions in water.
Which is the most common preparation for polyvinyl acetal?
Polyvinyl acetals are prepared by treating PVA with aldehydes. Butyraldehyde and formaldehyde afford polyvinyl butyral (PVB) and polyvinyl formal (PVF), respectively. Preparation of polyvinyl butyral is the largest use for polyvinyl alcohol in the U.S. and Western Europe.
