Clearfil K Etchant Gel Red

Thixotropic etching gel which is used to etch tooth enamel, dentine, ceramics, hybrid ceramics and cured composites for adhesive restorations. When you shake the bottle, the contents become liquid, simplifying the application. Reverts to the gel state when it comes in contact with oxygen, ensuring that only those areas which are supposed to be treated are etched. 40% phosphoric acid.
