Aislar from Kulzer is an alginate based, formaldehyde free, aqueous solution for the separation of plaster surfaces from denture acrylic and composites. There are also a variety of requirements for isolation such as a fast drying time, smooth surface representation and effortless separation. These characteristics are fulfilled by Aislar when used with heat and cold-curing denture acrylics. Based on optimized isolation properties, processing is reduced to a minimum.
