Mold Coatings

RH-200 Lubricating Mold Coating is a semi-colloidal dispersion of graphite in a water base, forming a continuous and smooth film with extra-long wear life and good high temperature wetting properties. It is used primarily as an aluminum permanent mold coating and provides superior release, improved surface finish, and longer tooling life. RH-200 Lubricating Mold Coating is available in a 5 gallon concentrate.

Mixing Instructions:
RH-200 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.

Application:
RH-200 Insulating Mold Coating should be applied to mold surfaces free of dirt, oil, grease, and previous coating. Preheat mold to at least 200 F, and apply mold coating with a good quality spray gun using air pressure of 35-50 psi.

Caution:
Mold coating should be protected against freezing temperatures at all times. Severe freezing may cause coating to take on a granular appearance and settle.

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.

Mixing Instructions:
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.

Application:
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.

Caution:
Mold coating should be protected against freezing temperatures at all times. Severe freezing may cause coating to take on a granular appearance and settle.
