Production Introduction

     This product uses high quality magnesite as the main raw materials and is obtained through special processing process combined with special binder, sintering agent and coagulant. It has advantages of good fluidity in high temperature, short hardening time, higher sintering strength and corrosion resistance, which is the ideal material for rapid hot repair of the front, back and bottom area.
