Silica-Titania composite oxide "SANSIL™FA"

SANSIL™ FA is a silica-titania composite oxide, which can control its refractive index.
By adjusting the ratio between silica and titania, the refractive index of SANSIL™ FA can be controlled from 1.46 to 1.60.
Produced by sol-gel method, SANSIL™ FA is spherical particle with narrow size distribution and its paticle size can be controlled from 0.3 to 0.7 μm.

Effect of refractive index-matching(epoxy resin)

Effect of refractive index-matching(epoxy resin)Adding SANSIL™ FA having the same refractive as regin, resin can be improved mechanical strength and get anti-blocking, while maintaining its transparency.
