Miracle Gloss Mould Release Wax

Mould release wax is the most traditional and still commonly used release agent in composites.

Easy Composites' Number 8 Mould Release Wax is chosen because of it's excellent release properties, easy application and exceptional mirror finish shine.

This handy 100g tin should provide hundreds of releases from small to medium sized moulds.

Typical Uses

Number 8 Mould Release Wax can be used on its own to provide a reliable mould release surface when making composites using polyester, vinyl ester and epoxy resin systems although it is not suitable for high temperature applications such as elevated temperature cure, pre-preg or wet-lay where exotherm in the part is likely to take the mould surface over 50°C.

Further Information

Application

Ensure the mould surface is properly sealed (porous mould surfaces such as wood or plaster must be sealed prior to the application of any mould release agent) clean and free of contaminants.

Using a clean, lint-free cloth collect a small amount of wax on the cloth (like you would shoe polish) and then begin to apply to the surface of your mould in small circular motions. Ensure you cover the entire mould surface, paying particular attention to any tight corners.

Allow the wax to dry which will cause its appearance to 'matt off' slightly making the swirls more apparent on the mould surface. This will take around 15mins.

Using a different, clean, lint-free cloth start to gently skim the cloth over the surface of the mould. This will start to gently smooth out the swirl pattern of the wax. Always keep you pressure very light, you want to polish the wax, not remove it from the mould's surface. Once the surface of the mould looks completely swirl free and shiny you should repeat the application of the wax about 3 more times, each time following the same procedure as above.

This depends upon the complexity of the mould, however it is not normally required, it is considered good practice to apply one extra coat between the first 5-10 releases, after this the mould can often release 5 or 10 parts without re-applying.
If you are in any doubt it's always best to be on the safe-side and apply an extra coat!

The wax has a maximum service temperature of 50°C which makes it unsuitable for high temperature applications such as curing pre-Pregs.

I guess this really depends on just how rough the surface of the aluminium is. If we're talking of lots of light scratches over the whole surface then it's very likely that mould release wax, such as the Miracle Gloss, would be sufficient to fill in the scratches on the surface of the part and ensure the mould releases without any difficulty. The more coats of wax you apply, the more likely this is to be the case.

However, if the scratches are really coarse, resulting in some of the aluminium almost sticking up from the surface then this would be more that the wax could infill and is likely to cause the mould to mechanically grip and lock onto this surface. If this is the case then no release agent is going to work reliably and instead you would need to improve the surface of the component (using abrasive paper and wire wool) until it's smooth enough and free of anything that the mould could grip onto. If you took the surface to an 800 grit abrasive paper then there wouldn't be any concerns.

Either way, mould release wax is a good release agent choice when you want to fill in some micro-texture in the surface of an original part or pattern. PVA is another good option, particularly if you were able to spray it so that you can build up more than one layer (more than one layer by wipe application of PVA isn't possible).

Yes, do people sometimes do this. If you're going to try then the sequence is wax then PVA, however, what you're likely to find is that the PVA 'fish-eyes' away from the wax so much that it's almost impossible to get any kind of a coating of PVA onto a waxed surface. You normally just end up with a few patches of PVA in some corners and then streaks/beads of it in lines where the wax has repelled it. If this doesn't happen then that's usually a good indication that you didn't do a very good job of applying the wax!

Providing you're using suitable materials for your patterns and/or moulds then it shouldn't ever be necessary to use both wax and PVA, just one (most often wax) applied correctly, will be sufficient.

Yes, providing your mould surface is suitable (non-porous) you can could use the Mould Release Wax to prevent resin from sticking to your mould surface.

No, we would not recommend attempting to use a mould release wax on sheet glass. It is very difficult to apply to glass and usually the end result is unreliable. Instead, we would always recommend using chemical release agent to make glass non-stick for resin infusion or any other lamination process.

Your best best would be a proper Mould Cleaner which will thoroughly clean mould release wax off a mould without being too aggressive and damaging the mould. Alternatively, for well cured and stable moulds, acetone can be used but is more aggressive than mould cleaner.

The wax is not suitable as a release agent on silicone. A simple good release agent for silicone to silicone is petroleum jelly brushed on in a thin layer.
