UT1 Uni-Mould Tooling Resin is a low shrinkage filled polyester laminating for composite moulds and tools. Its special filled composition is designed for use a rapid tooling system where all the mould reinforcement is laminated at the same time, making mould production significantly quicker compared to a conventional laminating resin.
This special filled tooling resin should be used as part of the Uni-Mould rapid tooling system.
Requires MEKP catalyst, not included. Available to buy online in 5kg tins.

Further Information
Application
The laminating technique for the UT1 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.
UT1 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.
Preparation
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 (UT1 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.
Begin Laminating
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.

The reason we can’t ship MEKP outside of the UK is because it is highly oxidizing, and standard carrier services do not permit it to be transported.
However you can purchase MEKP from any suppliers of composite materials including fibreglass (GRP) shops, roofing suppliers, boat buildings, car bodyshops etc. There is nothing special about the MEKP we supply, you can ask at your local supplier for ‘Standard reactivity MEKP’; brands such as Andanox KP9, Akperox A30, Butanox M50 (Akzo Nobel) are all suitable and widely available.
It's always worth testing a small amount on a discrete area first to check that the gelcoat wont attack the vinyl. If you still have the vinyl left over, you could even apply your chosen release agent and do a test with some of the gel to make sure that it releases okay. Apart from that it should be fine, applying vinyl over a part is a well used technique when the finish of the part may not be compatible with the chosen tooling gel and the original needs to be protected.
There is really very little you need to consider in terms of storing Uni-Mould moulds in the long term. We've had moulds that we've used for many years, sometimes using them every day, other times using them every few months. The only likely condition that could do them any harm would be if they were stored in very damp conditions or out exposed to the weather and elements. Because you'll have an exposed glass fibre edge, over time, water could 'ingress' into the glass fibre and the moulds would deteriorate; this would take a long time however and would need require constant exposure to wet weather.
It's also worth pointing out that if you're using a semi-permanent release agent, like Easy Lease, you would need to give your moulds a fresh coat of release agent when you use them again if they've been in storage for anything more than a few weeks.
Yes, you will need MEKP Catalyst to cure any of our Uni-Mould resins, including the Tooling Gelcoat. You can order the MEKP from the product page and can also find the MEKP separately here: MEKP Catalyst
Really, any more than 4 layers at a time would be risking the mould overheating. If you wanted to go thicker, then you will need to wait for the first 4 layers to cure, then key the surface and apply another 4 layers (you need the 4 layer thickness to give you the heat to cure the resin)
Uni-Mould Tooling Resin, and most resins, are highly temperature sensitive and should be cured at around 20°C where possible. The lower the temperature, the longer the cure but below 10°C, the cure is likely to stall completely. As such we cannot recommend using it at sub zero temperatures as it will not cure.
Hi Sjoerd, firstly, I'll assume that you have a good reason why you want 15mm thick mould; this is much thicker than would ever normally be required and will increase a lot the weight and cost of the mould. Normally, if a large mould needs extra rigidity (stiffness) it is usually better to create a support structure (using something like plywood) which can be laminated onto the reverse of the mould.
If you really do want to create a 15mm thick Uni-Mould laminate then it would be possible to make it up in 3 sessions of 5mm per session. Whilst it might be just about possible to increase the thickness up to 7.5mm per session, the increased thickness would significantly increase the risk of the system exotherming and reaching excessively high temperatures, potentially causing distortion to the mould. Better to stick to 5mm per layup session and not start the next session until the previous session is back down to normal room temperature.
