Mold release agent null for water removal die water soluble die-cast

摘要

PURPOSE: To obtain a water soluble releasing agent for die-casting, capable of without causing a dirt in the metal mold, keeping a stable dispersion, and having a good releasing property with a high heat resistance. ;CONSTITUTION: This releasing agent is characterized by containing a dispersing agent consisting of (A) an inorganic powder (mica, talc etc.), (B) one or more substance selected from a group of silicone, waxes, oil, fat, and metallic soap, (C) a surface active agent, and (D) a dispersing agent consisting of a smectite clay and a water soluble high molecular weight compound, and water. A content of the smectite clay and the water soluble high molecular weight compound is 0.1-10wt.pt. in the total dispersing agent of 100wt.pt., and a ratio between the smectite clay and the water soluble high molecular weight compound can be set as l:0.2-l:2 in wt. ratio.;COPYRIGHT: (C)1995,JPO
