PURPOSE: To prevent the lowering of curing temp. and the cracking of a film, to enhance the film properties such adhesive force, mechanical strength, flexibility, water resistance or wheatherability of the film and to increase the sterilizing power of water or the activating force of water at low temp.
CONSTITUTION: 5-45 pts.wt. of a fine magnetite powder B and 5-40 pts.wt. of a fine far infrared emitting powder C are mixed with 100 pts.wt of an inorg. coating compsn. A consisting of 100 pts.wt. (on a solid basis) of an inorg. binder with a silica/potassium oxide mol ratio of 4.0-5.3 prepared by melting 20-50 pts.wt. of ultra-fine particulate silica in 100 pts.wt. (on a solid basis) of potassium oixide and 1-10 pts.wt. of a fine inorg. fibrous powder.
