Uni-Mould Tooling Resin is part of the Uni-Mould™ universal mould making system and should be used in conjunction with Uni-Mould Tooling Gel Coat and Uni-Mould Coupling Coat to produce hard-wearing, polishable moulds of any size with zero shrinkage suitable for use in just about any composites process.

The laminating technique for the Uni-Mould Tooling Resin is quite different from conventional polyester tooling resin or laminating resins and it is essential that you familiarise yourself with this technique and follow the guidelines carefully in order for the resin to cure properly and result in a successful mould.
Uni-Mould Tooling Resin is cured by its own exotherm and must reach a temperature of 50-60°C during its cure in order to achieve its full properties. In order for this to happen your workshop environment needs to be between 18°C and 25°C and you must lay down a minimum of 4 layers of 450gsm or resin-rich (4:1) CSM onto the back of the mould in a single session.
In order to ensure that all the reinforcement can be laid down in a single session it is important to prepare the resin and reinforcement in advance before starting to laminate.
Cut your 450gsm CSM to the right shapes for your mould, allowing for a minimum of 4 layers of mat. Once you have cut the mat, weigh it to see how much CSM you will be using.
Next, weigh out 4 times the weight of the glass in resin (Uni-Mould Tooling Resin should be used at a typical 4:1 ratio or resin to glass) which means if you are using 5kgs of CSM to reinforce your mould you should prepare 20kgs of resin.
When you are ready, catalyse the resin using MEKP catalyst (not included) at 0.75 - 1.25% (depending on the ambient temperature) and mix thoroughly.
Working quickly, apply resin all over the mould and then add layers of glass one at a time, wetting with plenty of resin (4:1 by weight) until you have added all the layers of glass to the back of the mould. You should use the last of the prepared resin as you add the last layer of CSM.
As the laminate starts to cure the temperature will rise to 50-60°C and the colour of the laminate will change from a mid brown to a light brown colour.
Allow the resin to cure fully for 24hrs.
Use with Prepregs
Although it is possible to use Uni-Mould moulds with out-of-autoclave (oven cure) prepregs (such as XPREG® XC110) we no longer recommend Uni-Mould moulds for this purpose.
Instead – for prepreg use – better results will be achieved using high temperature epoxy moulds made using our EG160 / EMP160 tooling system or XPREG® XT135 Tooling Prepreg. These high temperature epoxy tooling systems allow the prepreg to be cured at the optimum 120°C which reduces the cure time and improves the mechanical properties of the component. Additionally, epoxy tools have been found to result in a better surface finish with prepregs such as XPREG® XC110.
Compatibility Information - Dos and Don'ts
Although by no means an exhaustive list, the mould materials, pigments and additives listed below have all been tested and are known to work well with GC50.

* Generally there is no need to pigment the tooling resin, although it is technically possible if you desire a certain colour mould back for branding or identification reasons.
Key Processing Information
Ease of Use
Suitable for professional and hobby use (follow SDS advice).
Tooling Resin has a strong styrene based odour.
Wear gloves and goggles and work in a well ventilated area. Always read the SDS before use.
Can be used from 15 to 30°C although pot-life and cure time will be affected significantly. Recommended working at an ambient of 20-25°C.
Not necessary. Simply mix and use.
Add MEKP Catalyst at a ratio of 0.75 - 1.25% dependent on ambient temperature. Use digital scales.
Mix thoroughly by hand for at around 2 minutes.
Can be applied by brush and plastic finned roller
The pot life at 20°C is 35 - 45 minutes. Be sure to use your resin before this time.
Resin will heat-up whilst it cures. Mix in small batches and use expediently. Mixed resin in a pot will quickly overheat (exotherm) and can smoke/ignite. Never leave mixed resin unattended.
Maximum Service Temperature
When fully cured and post cured, the maximum Service Temerpature of Uni-Mould moulds is 90°C
At 20°C the demould time is 24hours.
Where thicker moulds are desired, you can overcoat the tooling resin 1 Hr 30 Mins after the first layers have "whitened" and exothermed.
The Uni-Mould Tooling Resin is available in 2 different pack sizes: 5kg and 25kg. Please choose the pack size required from the drop-down list at the top of the page.
