PAINT CHEMICALS AND THEIR FUNCTIONS
- Calcium carbonate (Base matrix)
- Titanium dioxide (Titan)
- P. V. A
- Nitro sol
- Bama cork
- Marble Dust
- Aluminum silicate
FUNCTIONS OF THE ABOVE LISTED CHEMICALS
WATER : Water is used in mixing all the chemicals / materials together. In order to achieve homogeneous mix, Soft and clean water is recommended with a normal water temperature.
CALCIUM CARBONATE: This is the base matrix of emulsion and texture paint, meaning that without calcium carbonate there is no emulsion and texture paint. They are two types of calcium carbonate, they are Delomite (white) and Cacite (off white), both are very good. The Delomite (white) is recommended for absolute white or brilliant white, while Cacite (off white) is for dirty paint or off white paint and for any other color.
TITANIUM DIOXIDE: This chemical is popularly known as TITAN, it’s makes your paint looks shining. it’s mostly used when producing brilliant white paint. Note; Titan is still useful when producing other colour but more significant in brilliant white paint
P. V. A : The full name of this chemical is Polyvinyl Acetate, is a GUM that help your paint to stink together and to stink to the wall of the building. your paint will be stain free if you use the adequate proportion of the gum.
FORMALIN AND AMMONIA: These chemicals are very corrosive and they serve the same function. they are preservative, they prevent the paint from decaying and increase the paint durability.

NITRO SOL AND BAMA CORK: These chemicals also serve the same function. they increase the paint viscosity i.e it’s a thickener and also increase paint durability.
DE-FORMER: These chemical usually eliminate the foam that was formed during mixing of the various chemicals together paint production.
COLOURITE: They are two types of paint colours, they are oxide and paste. The oxide colour are in powder form, which means that they must be disperse with water for about 30 minute – 1 hour before introducing them into the paint mixture, if not so, you will experience un-dispersed oxide that will cause dotted stains as you roll your paint on the wall while the paste colour are in liquid form, meaning that you don’t have to be disperse them before introducing them into your paint mixture. Don’t worry about colour mixing and dispersion, all you need to do is to follow along with me.
KAOLIN : This is not use in production of all colours, but it’s used as a coverage to brighten your paint colour.
HYDRO SOL: This agent brighten your paint colour and it’s also used to correct dullness in paint.
MARBLE DUST: This is used only in texture or texcoat paint. They are two types of marble dust, they are rough and smooth dust. To achieve the best texture, you need the combination of both the rough and the smooth in the same and equal proportion.
GENIPOLE : this is an extender; it’s help your paint to spread over a large area when painting.
TEXANOL: This is a lamina, it’s help the paint to be shining and durable. It’s very expensive and it is used for the production of satin paint. with these chemical you can watch off stain from your paint without any effect on the paint.
ALUMINUM SILICATE: This is usually used in the production of brilliant white paint, it’s make the paint to be very tough and strong.
