PURPOSE:To provide a resin separator for dental use which is fast drying and forms tenacious separating film, prepared by blending sodium alginate, monosodium phosphate, trisodium phosphate, water, alcohol and aqueous silicone rubber. CONSTITUTION:The resin separator consists mainly of a compsn. obtained by blending sodium alginate, monosodium phosphate, trisodium phosphate, water, alcohol and aqueous silicone rubber. Sodium alginate and aqueous silicone rubber form separating film. Monosodium phosphate and trisodium phosphate improve adhesion of sodium alginate to gypsum. Water and methyl alcohol act as solvent. When necessary, preservative such as citric acid may be added. |
