Light-curing radiopaque one-component glass ionomer composite for cavity linings. Mixing is not required: Ionoseal can be directly applied from the syringe; time-saving and economical. High physical strength provides durable linings. Ionoseal is thoroughly polymerised with a standard halogen device within 20 seconds (2mm). Acid-resistant and bonds well to composites and compomers. Releases fluorides for secondary caries prevention.
