DAG 193 is a concentration of refractory pigments in a water base designed specifically as an aluminum permanent mold coating. The coating functions as an insulator providing controlled solidification of the molten metal, thus ensuring high quality castings. DAG 193 is recommended for use on large surface area castings where additional insulation is needed. It offers protection against mold erosion and increases mold longevity while decreasing downtime. DAG 193 is nontoxic, nonflammable, and smokeless which promotes a cleaner work environment. Available as a 5 gallon concentrate.
DAG 193 concentrate should be diluted with water before use. Mildly agitate the concentrate with a mechanical mixer prior to dilution. While stirring the mold coating, slowly add water until the desired dilution is achieved determined by your particular application. For initial use, a ration of 1:4 (mold coat : water) is recommended.
DAG 193 should be applied to mold surfaces free of dirt, oil, grease, and previous coating. Preheat mold to at least 350 – 400 F, and apply mold coating with a good quality spray gun using air pressure of 35-50 psi. Stir the coating occasionally during use to prevent settling.
Mold coating should be protected against freezing temperatures at all times. Severe freezing may cause coating to take on a granular appearance and settle.
