GC EUROPE GRADIA - Manual (Page 8)

GC GRADIA provides superior physical properties and beautiful, natural aesthetics. The unique
chemistry of GC GRADIA couples its micro-fine ceramic/pre-polymer filler with urethane
dimethacrylate matrix to produce a unique ceramic composite with exceptionally high strength
and wear resistance.
As a consequence, GC GRADIA can be safely used also in those cases in posterior areas where
often chipping and cracking problems occur.
