Characteristics of SYLYSIA
SYLYSIA® has a sponge-like structure with different degrees of porosity that varies from low (0,4 ml/g) to high (1,8 ml/g) pore volumes.
Low pore volume grades present reduced liquids absorption capacity and therefore limited influence on viscosity. High pore volume grades are characterized by higher matting efficiency thanks to their higher volume (number of particles) per unit weight.
B. Surface Treatment
SYLYSIA® grades are characterized by high specific surface area (300-700 m2/g).
Surface treatment is applied to the product in order to improve the performance in various applications.
In most SYLYSIA® grades an organic treatment, based on different wax types, is applied in order to meet specific needs, as for example: prevention of the formation of a hard sediment and improvement of the mechanical properties of the applied paint film
C. Particle Size
Each SYLYSIA® grade has a specific and controlled particle size distribution.
The particle size is immediately relevant to the matting efficiency, smoothness and transparency of the applied paint film.
In most applications, the selection of a suitable SYLYSIA® grade with a specific particle size is governed by the thickness of the applied film.
