ABSTRACT:
The agent basically consists of Saxolith, a crystalline marble-based filler, and Erkamar, a binder having adhesive properties. The agent preferably also contains dimethylethanolamine to improve the dissolution of resins and to stabilize the pH, as well as isopropanol as the diluent, Sipernat to improve the flow properties, Agitan as defoaming agent and coagulant, as well as Byk to improve the flow properties and as a filler. The agent is produced by adding Erkamar to at least the same quantity of water, mixing it and stirring it for a few hours, cooling the mixture to room temperature, and adding at least the same quantity of Saxolith as that of Erkamar added previously and stirring until a homogeneous mixture is obtained.
