Industrial Adsorbent
SYLYSIA
Paint / Ink / Plastic / Paper / Other industrial

SYLYSIA is Fuji Silysia Chemical’s micronized synthetic amorphous silica-gel product line. This material is highly versatile and can be used in many industries, including paints & coatings, plastics, inks and adhesives & sealants. SYLYSIA is an excellent agent for matting and anti-blocking polymer film. With variable pore volume, particle size and density, SYLYSIA can be widely applied into the paper and ink industries to improve receptivity and other functional coatings. 

FEATURES

Porosity Control

SYLYSIA has the variety of grades with controlled porosity. It makes possible to control from high density and small pore volume like SYLYSIA 700 series to low density and large pore volume like SYLYSIA 300 series. Besides, the adsorption isotherm also differs depending on the difference in pore diameter and pore volume. The SYLYSIA 700 series shows high moisture absorption rate at low humidity, while not high at high humidity condition. On the other hand, the SYLYSIA 300 series shows high moisture absorption rate at high humidity, exceeding to 1.4 times against its own weight. The other grades which have intermediate characteristics between the above can be available as well in the product line-up.

Controlled Particle Size

Controlled Particle Size

The particle size distribution is controlled under the range shown in the left figure. The smaller the particle size, the sharper the particle size distribution it shows. It is possible to control the particle size based on the corresponded application.

Surface Treatment

The silica surface is covered by the hydroxyl group    (OH group) called “Silanol”. SYLYSIA treated with organic substances is available to improve the compatibility with solvents and resins. Furthermore, it is possible to improve the surface characteristics by corresponding its application.

PURPOSE

Industrial Applications

SYLYSIA is widely used as the matting agent for the variety of paint and inks. We can recommend the best suitable grades for each target gloss value.
SYLYSIA is used as the anti-blocking agent in plastic film. It is effective to prevent the plastic film from cohering and piling, and it helps for easier separation of polymer films. It also prevents from the transfer of printed ink to other surfaces.
SYLYSIA is widely applied into newspapers, inkjet papers, synthetic papers, diazo photosensitive papers, and second original drawings. SYLYSIA helps to improve printing performance and color development.
