This amorphous titanium phosphate which have anti-biotec function, deodorizing. and stain-proofing effect in dark places without ray radiation has been developed by reaction phosphoric acid and titanium oxide which is known as ray active photo catalyst. Activated bay sun's ray (Ultra Violet ray) irradiation and it is achieved by cooperation with Osaka city Industrial Laboratory. ECOKIMERA series are commercial products based on this technique.

Non color transparent liquid

Non color transparent liquid, Titanium phoshate of ECOKIMERA(R) is able to adhere strongly on substrates such as fiber, woods, glass, metals, plastics and paints without organic binders and the durabilities have been evidenced by 50 times of washing test, 10,000 times of rubbing test for abrasion.

Mutability Test

Abstract
In Accordance with Ministry of Labor Notification No.77(Sep.1.1988)mutability of SW-50 was evaluated. To evaluate reverse mutation including metabolism on 100~500オ/plate of SW-50, Escherichia coli WP2uvr and 4 types of Salmonella typhimurium TA were used. Reverse mutated colonies are not observed every specimen. So SW-50 does not have mutability in the condition above.
