BONASIL A+ Crystal Vision is a transparent laboratory vinyl polysiloxane (VPS) impression material with medium viscosity. Its novel formulation produces highly transparent matrices through which the lab technician can polymerize light-curing composites and detect the accurate waxing placement and the reproduction of composite. Indications: Transparent matrix for creating masks for the moulding of light-curing resins Characteristics-Advantages: Outstanding transparency Exceptional dimensional stability High final hardness Highly thixotropic Ideal consistency Very high tear strength Void free Composites free from oxygen inhibition layer
