S-630 is the newest product launched in 2012. The strength has reached 9000psi unbeatably. It shows the highest technique of capping gypsum at present all over the world and the R&D ability of TAIWAN CAPSTONE Lab. The holding time is slightly longer than any other products at 40 mins. It fits the highest strength concrete compressive test.
The water to gypsum ratio for S-630 is recommended to be 15.5-16%. After simply mixing with water, it can be used immediately. The gypsum will fully harden after 30 minutes and reach the strength over 630 kgf/cm2, equals to 9000psi
