Sealant is 56% filled to provide long-lasting barrier and wear protection. Excellent flow properties ensure penetration into the smallest pits and fissures. Innovative and patented SmartCap™ technology utilizes semipermeable resin microcapsules filled with ionic solutions of fluoride, calcium, and phosphate, which diffuse in and out of the sealant. Bioavailable ions can strengthen enamel and seal margins against microleakage. Additionally, the remineralization compounds present an extra line of defense during acid attacks.
