The CHMA602 PRO is a two-part methyl methacrylate structural adhesive, specificallydesigned for ceramic,sintered stone basin. It is custom-colored to match ceramic basinand used for seamless bonding between ceramic basin and sintered stone.
When CHMA602 PRO is used with a hardener at a ratio of 10:1, the operating time is 6-12 minutes, the initial curing time is 15-25 minutes,and the grinding time is 25-30 minutes. After hardening, CHMA602 PRO exhibits high bonding strength, fast curing, excellent UV stability,yellowing resistance, high-temperature resistance, good water resistance, good impact resistance, and abrasion resistance.
