ZINC OXIDE
This is a low-viscosity dispersion with high dispersion stability, consisting of highly concentrated fine zinc oxide particles dispersed in volatile silicone fluids.
It has a smooth, non-sticky feel and can be used to manufacture high PA products.

(Not specified values)
The SPD series uses dispersants with high dispersion performance, enabling stable dispersion of high concentrations of fine particles and resulting in low-viscosity dispersions for all products.
SPD-Z5 is recommended for applications requiring high transparency.
SPD-Z6 is recommended for those who want more efficient protection against UVA rays.
Transparency of SPD-Z5
The photo on the right was taken through a glass plate coated with SPD-T5 (using a 6 µm thick wire bar).
Due to its high transparency, the text underneath is clearly visible.
Transmission Spectrum of SPD-Z5
SPD 30% formulation applied at a thickness of 6 µm and measured.
