Talc is used in polymer paints as an additive or filler in order to improve and expand paint properties. Described below are several purposes of using talc in polymer paints:
- Improved mechanical properties: adding talc to polymer paints enables improvement in their mechanical properties, such as durability, shock resistance and deformational stability. Thus, paints become more resistant to mechanical damage, wear and tear.
- Improved adhesion: talc enhances paint’s adhesion to the surface, which it is applied to. This enables a better adhesive capacity and reduces the risk of paint peeling off the base layer.
- Improved coating and masking: with its high brightness and optical stability, talc allows improving the surface coating and masking. It may help conceal imperfections and irregularities of the base layer securing a smoother and higher-quality coating.
- Improved flow and viscosity: talc may be used to control paint flow and viscosity in order to improve its application and secure its uniform distribution on the surface.
- Improved resistance to chemical impacts: adding talc enables increased chemical resistance of polymer paints making them less prone to damage when contacting with various aggressive chemical environments.
- Gloss and dullness control: talc may be used to control paint gloss and dullness levels. Depending on the application and the desired finish type, different kinds of talc may be chosen.
- Reduced density: talc is a lightweight material, which, if added, allows reducing density of polymer paints. This may be useful where achieving a lower weight of the coated surface is needed.
- Improved thermal resistance: talc improves thermal resistance of polymer paints making them less sensitive to high temperatures and thermal impacts.
Using talc in polymer paints enables their improved and diversified properties, which contribute to higher quality, efficient application and durability of resulting coatings.
