Mold Coatings

RH-198 Insulating Mold Coating is a concentrate of refractory pigments in a water base. It is used as an aluminum permanent mold coating and works as an insulator for controlled progressive solidification of the molten metal ensuring high quality castings at high production rates. This product also protects against mold erosion, resulting in better tooling life. RH-198 Insulating Mold Coating is available in a 5 gallon concentrate.

Mixing Instructions:
RH-198 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-198 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.

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.

DAG 632 Refractory Mold Coating is a concentrate of refractory pigments specifically designed as an insulating coating for various casting applications such as permanent mold and low pressure casting. DAG 632 adheres particularly well to mold surfaces and has high abrasion resistance. This mold coating can also be used as a gate and rider coating to control metal flow and solidification rate. The fine particle size of the DAG 632 improves casting surface finish while proving excellent insulation – 10.1W/mk thermal conductivity at 2 mils coating thickness. Available as a 5 gallon concentrate.

Mixing Instructions:
DAG 632 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. Typical ration should be 1:1 (mold coat : water). Periodic agitation should be maintained.

Application:
DAG 631 should be applied to mold surfaces free of dirt, oil, grease, and previous coating. Preheat mold to approximately 300 F, and apply mold coating in thin multiple coats with a good quality spray gun using air pressure of 35-50 psi. Allow coating to air dry for 20 minutes before use.

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 633 Insulating/Lubricating Mold Coating is specifically designed to provide both an insulating and lubricating coating for applications such as low pressure casting and permanent mold casting. combining lubricating and refractory pigments, DAG 633 provides a very durable coating. This mold coating promotes superior solidification, metal flow characteristics, and mold release properties. DAG 633 will not stain, is resistant to aluminum and magnesium adhesion, and can withstand temperatures up to 2000 F. The fine texture improves casting surface finish while proving excellent insulation — 10.3W/mk thermal conductivity value at 2 mils. Available as a 5 gallon concentrate.

Mixing Instructions:
DAG 633 concentrate should be diluted for most applications. 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. Typical ratios will vary from 1:1 to 1:5 (mold coat : water). Periodic agitation should be maintained.

Application:
DAG 633 should be applied to mold surfaces free of dirt, oil, grease, and previous coating. Preheat mold to approximately 350F, and apply mold coating in thin multiple coats with a good quality spray gun using air pressure of 35-50 psi. Allow coating to air dry for 20 minutes before use.

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.
