Additives are added to the color compound in order to accelerate dye drying and prevent the production of fungi. Talc causes strength in layers and prevents dripping and also it is used to prevent solid particles from settling in paint. This mineral reduces the requirement to consume expensive titanium dioxide in paints Talc particles strengthen the paint texture and reduce cracking and cause resistance to gradual wear and humidity in oil dyes. Talc is odorless. It is not soluble in water, weak acids and alkaline substances. Although talc has a certain tendency to some organic chemicals, it has very few chemical reactions. It is neither explosive nor flammable. Talc melting point is 1500 °C, above 900°C, it gradually loses its hydroxyl groups and above 1,050 degrees Celsius, crystallizes in different forms of statite (anhydrous magnesium silicate).
