ALWA SIL SH System
Silicone rubber ALWA SIL SH 22 and SH 33 are silicone impression materials. These materials have extremely high mechanical values. In addition, they are very fast to handle and very easy to handle as well.The two-component silicone rubbers cure at room temperature. After mixing the two components, a low viscosity liquid develops, which crosslinks to a resistant and rubber elastic material. During the crosslinking, no exothermic heat is developed. When 1 – 3 % thixotropic agent is added per component, a spreadable mixture is obtained.
