Partall® Paste #2 is a wax-based, silicone-free mixture designed for use on the mold surface prior to application of PARTALL® Coverall Film or as a universal release agent/edge wax.
- For Epoxy-, polyester- and vinylester resins
- Useable up to 60 °C
A blend of hydrocarbon and microcrystalline waxes. For high-gloss surfaces. Ideal for smooth and sealed surfaces e.g. on GRP moulds.
Polishing possible after a drying time of: approx. 1-2 minutes
Could be used in conjunction with film release agent PVA.
Available in green and colourless.
It is particularly recommended for use on moulds where standard silicone waxes hinder post-finishing operations or as a primer coat prior to the application of PARTALL® Coverall Film.PARTALL® Paste #2 may also be employed as an economical edge wax on larger molds, and is used to seal rough wood moulds or plugs for casting composites, cements and grouts.
Maximum processing temperature: 60 °C
Mould surface preparation
Before application of PARTALL® Paste #2 porous molds (i.e., plaster or wood) should first be cleaned and sealed. Composites grade sealers and fairing compounds (body filler) are recommended but a good surface on plaster or wood may be obtained with automobile type primer-sealers and lacquers. For non-cosmetic parts with rough wood molds or plugs a number of coats of PARTALL® Paste #2 should adequately seal the surface.
Application instructions of the manufacturer:
The mould surface should be thoroughly cleaned before use. Using a clean dry rag, apply a thin even coat of PARTALL® Paste #2 to mold surface, covering 3-4 square footsections at a time. Excess should be wiped away, also using a clean dry rag. Begin buffing approximately one minute after application (wax can become difficult to polish out if left to soak in for longer periods). Polish to a glossy finish. For this application we recommend our cleaning and polishing cloth (Art. No. 365-SHT). Note: One layer is sufficient for 3 to 5 cycles on a finished mould. In order to insure complete coverage, repeat entire process 3-4 times for initial molding cycle. One coat per cycle is then sufficient. Apply additional PARTALL® Coverall Film until the mold is complete.
Consumption: 20-60 g/m2 (quantity depends on the condition of the mould surface)
For mould surfaces that are extremely smooth (low to no surface roughness), it is advisable to polish carefully or better not at all, as otherwise there is a danger that the release agent application will be removed again (at least in places).
In the original Rexco manual which we have translated here, the author assumes that the user is a professional processor from trade and industry who has the appropriate routine in the processing of composites and therefore also with release agents.
If you do not yet have this experience as a first processor, we recommend that you refrain from polishing until you have a feeling for the wax build-up and the release effect. It is better not to polish the release wax or only to polish it very little and carefully, and later remove a component from the mould with a silk-matt glossy surface than to polish a mirror-smooth mould surface and then possibly not get the component undamaged out of the mould, as it partially sticks to the mould surface.
