Mould release wax is the most traditional and still comonly 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.
Suitable 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 temeperature cure, pre-preg or wet-lay where exotherm in the part is likely to take the mould surface over 50°C.
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 contaminents.
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 completly swirl free and shiny you should repeat the application of the wax about 3 more times, each time following the same procedure as above.
