VS101 is a two-part floatable Vinylpolysiloxane impression material specifically used for instant in-office swim and sound plugs. The material is blended by kneading Part A (Base) with Part B (red or blue). The material cures in 10 to 15 minutes. The material can then be coated with the VS101 sealer. VS101 sealer must be refrigerated. The kit includes one base, red and blue material, 3 spoons, and VS101 sealer. Opened material is not eligible for return.
