Our Data
Tack is described as a measure of how quickly an adhesive bond is formed when two surfaces are brought together with light pressure with brief contact.
The more negative value represents greater adhesion.
In this test a probe is brought into contact with the formulation at a fixed speed, contact pressure, and contact time. The tack is then recorded as the maximum force required to break the resultant bond.
The work of adhesion correlates to the adhesive or cohesive strength of a formulation.
The more negative value represents greater adhesion.
In this test a probe is brought into contact with the formulation at a fixed speed, contact pressure, and contact time. The work of adhesion is calculated by measuring the area under the force–time curve.
PROFISIL
Profisil Fluoride Varnish contains 5 % sodium fluoride in a mucosa-friendly, pleasantly flavored dimethicone gel. This formula does not contain ethyl alcohol or colophony (rosin), thus reducing the potential of soft tissue irritation or rosin-based allergies.
