Two-component satin topcoat for bodywork, furniture, woodwork, concrete, metals.
This topcoat is not only reserved for bodywork, it can be used successfully in the areas of industry and decoration.
The main quality of the ST-819 Satin Topcoat is its high resistance. It is also thin, very hard, easy to apply, and delivers fast drying.
Very high hardness: 3H
It is also possible to apply the product on plastics and metals.
Very high resistance to chemicals and abrasion, great stretchability and quick drying
Satin effect 60°:
A satin effect is half way between gloss and mat finish.
The ST-819 Satin Matte Topcoat creates a semi-gloss finish: the surface is glossy and reflects the light, but never shows a "wet" effect, such as seen with classic glossy bodywork clear coats.
The ST-819 Satin Matte Topcoat is usually intended for vehicle bodies (car, motorcycle, scooter, bicycle), but is also suitable for other non-automotive specific applications: furniture, microcement floor, equipment.
Direct adhesion on bodyworks, cement, plastics and metals
