Dental Aluminum Oxide Micro Blaster Four-Hole Interface Microetcher Sandblasting Alumina System Dental Instrument. Alumina sandblast guns have proven to be the most valuable tools in the dental field thanks to their effective. Powerful effects and extensive application methods. Alumina sandblasting guns provide precise surface micro-grain treatment that can increase adhesion up to 400%. The surface that has just been etched is more active, so it can increase the chemical adhesion and optimize the bonding effect. It can be applied to all metal materials, composite materials and ceramic materials. High-temperature and high-strength engineering material sand tanks to ensure a firm grip structure. High sensitive touch switch, start and stop by the heart. Convenience and gas connection. Product use for : to increase the viscosity of the tactile surface, roughening. The surface of the metal composite material, tungsten Steel, fiber post, inlay surface. Aluminum Oxide, 90 micron, tan Rapid removal of cements from metals. Preparation of metals for bonding. Aluminum Oxide, 50 micron, white General bonding preparation of metallic and nonmetallic surfaces. (Will not discolor porcelain or composites). Microprophy B, white Stain removal. Pit and fissure preparation. SA-85 Remove resin paste without enamel erosion. Glass Beads, 90 micron, white Satin luster texturing metal surfaces to reduce brightness. Not for bonding or intraoral use. 1 x handpiece connector (1.8m flexible tube/ joint). 1 x sand tank. 1 x user manual. Air Flow Polisher Blue/Clear 4holes/2holes. Skin-like texture, Various colors available. Perfect fit on the hand, relieves grip fatigue. Transparent Windows Design, easier observation of remaining powder. Two-section air-polishing handpiece design. Detachable handpiece, handpiece can be detached for maintenance if clog occurs. The handpiece can be rotated 360°, By adjusting different angles, it can clean the lingual side, labial side and adjacent space. Connect through quick connectors, easy quick connection for plugging and using. The recommended pressure of water supply. 0.15 MPa to 0.4 MPa. 0.25 MPa to 0.4 MPa. AAmbient temperature:5? To 40?
