TRANSPARENCY OF POLYESTER RESINS


Beside rheological and mechanical properties, which are the most important for many applications sometimes appearance is another aspect in focus. Especially in applications like decorative surfaces of furniture or wooden floors which are made shiny by a clear coat, corrugated sheets for transparent walls or industrial glazing or clear gel coats for fiber reinforced plastics.

The transparency of such formulations is influenced essentially by two factors: the particle size of the silica and the refractive index of the system.

Due to its fine particle size AEROSIL® 200 leaves clear resins more transparent than some other additives or fillers do. For most polyester applications AEROSIL® 200 works just fine.



If the transparency has to be improved further the grades AEROSIL® 300 or AEROSIL® 380 with higher active surface areas are recommended.
