Be careful：
The polymerized resin used in Durakote 651W will react when it is preheated. Please store it in a cool place (not near the hot mold). Durakote651W can be used directly without mixing and shaking.
Mold cleaning:
It is necessary to clean the mold before operating the product.
The mold must be clean and dry before use. If necessary, mold cleaning must be done (e.g. sand, sand blasting or dry ice). If possible, then use the solvent type cleaning agent to wipe the mold again, for example, the mold cleaning agent Durakote PMC-600.
If a semi permanent release agent has been used on the surface of the mold, Durakote 651W can be covered again. But if you first remove the products you used before, you will get the best release effect.
Application - spray use:
Before spraying Durakote 651W products, make sure the mold surface is clean, dry and remove all previous dirt.
Durakote 651W can use spray gun (for example: SCHUTZE SPRITZTECHNIK spray gun W3/FZ-Duo). For more information, please contact us at any time.
Most of the operation of the most suitable spray gun is SCHUTZE W3/ FZ-Duo, 90 degree fan and 0.5UM nozzle spray gun.
