The recommended steps in coating a mold with TraSys® follow. These steps can be accomplished in-house, if you are equipped with an oven that will bake the coating on at 360°C (680°F). Molders who want to use TraSys® but lack the proper equipment should contact DuPont for alternative coatings or for names of third-party companies that specialize in this area.

1. Place the mold into an oven and raise the surface temperature to over 371°C (700°F) for a period of 30 minutes. This will turn any excess rubber deposits to ash, but more importantly, will burn any previous release out of the mold's pores, thereby thoroughly cleaning the mold.
   NOTE: The burning off of foreign materials is only recommended prior to the initial coating of the mold or before any application of these products where contamination may have occurred. This step may not be required if no other release coatings or lubrication products were used in conjunction with these products.
2. The mold should be bead blasted, have the dust blown off, and then wiped with solvent using a clean rag. A recommended alternative is to spray the bead-blasted mold with solvent and blow dry with filtered air.

1. DuPont Coating & Release Systems TraSys™ can be applied with a pressure-fed tank sprayer such as those manufactured by Binks or Devilbiss.
2. Gun pressure should be regulated to a maximum of 25 psi, and pot pressure kept to the minimum pressure necessary for application, 5 psi or less.
3. With the mold at room temperature, spray four light coats, once from each direction, to coat places that may have been shadowed from raised parts. The spray will go on wet, dry quickly, and then turn white when all solvents have evaporated. This enables the operator to see any areas that may have been missed.
4. Touch up as necessary for complete coverage. There is no problem with overlapping of the spray causing discoloration of the finished part as with some other mold releases.

2. Gun pressure should be regulated to a maximum of 25 psi, and pot pressure kept to the minimum pressure necessary for application, 5 psi or less.
3. Material must be sprayed in a fine mist; a 0.028 inch fluid nozzle is recommended.
4. Mold surfaces must be hot (99-104°C [210-220°F]) for rapid water evaporation. After spraying, molds should be removed to oven as soon as possible.

1. Insert mold into bake oven.
2. The melt temperature window for these products as measured on the mold surface is 360-366°C (680-690°F). It is essential that the coated surfaces reach this temperature range and that this temperature is held for at least 10 minutes, but not more than 60 minutes. Excessive time at this temperature will degrade the coating. For optimum coating performance, we recommend a mold surface temperature of 360°C (680°F). When these conditions have been reached, the oven should then be turned off and dampers opened to allow quicker cooling of the mold.
   

1. Place mold into oven set at 315-327°C (600-620°F).
2. When the mold surface temperature reaches the required temperature range of 315°C (600°F) minimum -327°C (620°F) maximum, maintain this surface temperature for a minimum of 1 hr. This pre-cure bake will drive out the remaining moisture and dissipate surfactants and emulsifiers.
3. Immediately upon completion of pre-cure, increase oven temperature to 360-365°C (680-690°F).
4. It is essential that the coated surfaces reach this temperature range and that this temperature is held for at least 10 minutes, but not more than 60 minutes. Excessive time at this temperature will degrade the coating. For optimum coating performance, we recommend a mold surface temperature of 360°C (680°F). When these conditions have been reached, the oven should then be turned off and dampers opened to allow quicker cooling of the mold.

NOTE: Temperature can be conveniently measured by attaching a thermocouple to the coated mold surface. Measurement of oven air temperature, rather than mold surface temperature, may be misleading in determining whether the proper melt temperature has been reached.
