ABSTRACT
Mikrosils requires a two-part formulation: one tube is larger, has the consistency of toothpaste, and contains the base material; the smaller tube contains a blue-colored catalyst, which hardens the base material when both are mixed with one another (Figure 4.5a). An approximately 2” strip of base material is squeezed onto a weight boat, followed by an approximately 1.5” strip of the blue catalyst. A wooden spatula or tongue depressor can be used to mix the two components together for about twenty to thirty seconds until the color of the blue catalyst is no longer visible in the base material. The mixing time must be kept to a minimum, since the material begins to harden after about thirty seconds (Figure 4.5b). Accutranss is a polyvinylsiloxaine casting agent that also requires a two-part formulation; however, the product is in the form of an automix gun that allows direct application to the fingers using a spreader tip (Figure 4.6).
