Product Description

Partall® Paste #2 (one 24 ounce can) is a polishing compound produced from a combination of hydrocarbon and microcrystalline waxes. It is particularly recommended as a primer coat to create a smooth, compatible mold surface prior to application of Partall® Film #10.

Partall® Paste #2 is also useful as a general purpose parting agent, especially on molds where standard silicone waxes hinder post-finishing operations. Partall® Paste #2 may also be employed as an inexpensive edge wax on large molds.

It is recommended that Partall® Coverall Film or Partall® Film #10 be used in conjunction with Partall® Paste #2 to achieve adequate protection on molds that are particularly intricate or too expensive to risk demolding problems.

PREPARATION OF MOLD SURFACE

Porous molds (i.e., plaster or wood) must first be sealed with lacquer or similar coating. A good surface on plaster may be obtained with automobile type primer-sealers and lacquers. Plaster molds must be completely dried.

Mold surface should be thoroughly clean and free of other parting agents, especially those containing silicone, prior to application of Partall® Paste #2.

APPLICATION OF PARTALL® PASTE #2

New Molds: Using a clean dry rag, apply a thin even coat of Partall® Paste #2 to mold surface, covering 3 to 4 square foot sections at a time. Excess should be wiped away, also using a clean dry rag.

Begin buffing immediately (approximately one minute after application), preferably using a power buffer equipped with a terry cloth or lamb’s wool pad. Keep power buffer moving constantly so as not to allow a build-up of friction that could burn through the wax coating. Surface should be buffed to a glossy finish.

In order to insure complete coverage of mold surface, repeat entire process 3 to 4 times for initial molding cycle. Alternate rubbing motions during application of each coat (i.e., up-down on one coat, left-right on another, circular on another).

Wait approximately one hour after application of final wax coat before proceeding with molding process. Apply one coat of Partall® Paste #2 following every cycle thereafter until mold is broken in.

Conditioned Molds: Using the same process described for new molds, apply one coat of Partall® Paste #2 to mold surface and buff. Re-wax mold as necessary.

REMOVING PART FROM MOLD

The best procedure for separating the part from the mold depends on the size and shape of the part. In most cases the part can be lifted from the mold after loosening around the edges. A jet of air between the part and the mold at the edge is sometimes useful.

On large curved parts it may be necessary to first tap over the surface with a rubber mallet. A very strong blast of air (or a few squirts with a CO2 extinguisher) will free very rigid parts that cannot be flexed.

On a well-conditioned mold, the part should loosen and fall away easily. Using Partall® Paste #2 regularly can assist in the conditioning process, reducing parting problems and increasing production cycle efficiency.
