Mold Preparation

It is essential that the mold surface be thoroughly cleaned so that all traces of previous waxes used and/or other release agents or any foreign materials are removed. Durekote PMC-600 will remove waxes and wax residue. It should be noted, hower, that the Durekote PMC-600 breaks down the wax and, therefore, must be removed from the mold surface. A clean cloth should be used for this purpose to ensure that the dissolved wax is completely removed and not merely being spread.

Continue the process until the surface is completely clean. To test the surface for cleanliness, use a piece of masking tape on various points on the mold surface. Good adhesion to the mold should be noticed when removing tape. If not, further cleaning is necessary.

Application

Once the mold surface has been thoroughly cleaned, Durakote Wax #10 can be applied using a soft cotton cloth, being careful not to scratch the fibreglass mold surface. Do not power buff Durakote Wax #10.

1. Apply a thin, even film of Durakote Wax #10 using circular motions and making sure there is complete uniform coverage.

2. The coating should be left to haze completely. This process should take approximately 15 minutes depending upon ambient temperatures and humidity. Hazing is an important step, as all the carriers (mineral spirits) should evaporate completely before buffing. The wax film should be totally dry.

3. Buff the surface to a luster using a fresh, clean absorbent cloth.

4. Wait approximately 10 to 15 minutes before applying another coat of Durakote Wax #10. This should be down following Steps 1, 2 and 3. Five to seven applications initially will effectively fill the pores and coat the mold surface (The number of coats depends upon the porosity of the mold).

5. Once a part is pulled, apply two more coats of Durakote Wax #10 following Steps 1, 2 and 3.

6. For the third part, a single application will suffice. From this point on, multiple pulls can be achieved.

Note: In high humidity conditions, it may be necessary to give the mold a final wiping with a clean, dry cloth to remove any haze that develops from unreleased solvents. In order to avoid contamination, a clean cloth should always be used when applying and buffing this product.

Also recommended, is the use of our Durekote 615 as a sealer. This will provide superior smoothness and effectively seal the surface of the tooling mold before applying the Durakote Wax #10. The use of the sealer to new molds ad plugs during the break-in period will protect the Durakote Wax #10 coating from being attacked by styrene migration.

Durakote Wax #10 is available in 11-ounce cans, 12 cans per case.
