Blue Edge

37% Phosphoric Acid Etching Gel
Syringe 3.0 ml Blue Etch is in the form of 37% phosphoric acid gel. Blue Etch creates
microscopic spaces in the tooth enamel (increasing the surface Blue Edge
roughness) which results in very good bonding (micro-mechanical
retention).
When drying, the etched surface appears white. Blue Etch also removes
surface contamination and helps keep tooth enamel moist. (It removes the
smear layer and the hybrid layer.)
