Alginate impression materials have been a staple of dental practice. However, their hygroscopic nature and their tendency to deform in humid weather make storage and handling a bit worrisome. Dusting of dental alginates is another problem and dust free alginate comes at a premium. We believe that dental alginates being dust free is hygiene to the product. Our dust free dental alginate - Chromalgin® is available in 450 gm pack.
