High performance, unfilled vinylester laminating resin. Uni-Mould Coupling Coat offers excellent cured mechanical properties, low shrinkage, high service temperature and excellent chemical resistance. It can be used on its own as a vinylester laminating resin or as the coupling layer in the Uni-Mould rapid tooling system.
Requires MEKP catalyst, not included. Available to buy online in 1kg, 5kg or 25kg tins.
AVAILABILITY:6 in stock available for immediate shipping

If you believe you’re buying an equivalent product cheaper elsewhere, contact us to discuss your requirements.
Uni-Mould Coupling Coat 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 Tooling Resin to produce hard-wearing, polishable moulds of any size with zero shrinkage suitable for use in just about any composites process.

Further Information
Application
The Uni-Mould Coupling Coat is designed to eliminate print-through of the mould reinforcement, to reduce the risk of blisters underneath the gel coat by ensuring the gel is reinforced with a skin of resin and glass and to provide an ideal substrate for the main reinforcement.
Uni-Mould Coupling Coat should be catalysed with standard MEKP catalyst (not included) at 1.5 - 2%. Apply a layer of the coupling coat over the mould surface and then two layers of 100g chopped strand mat . We do not recommend the use of glass surface tissue in lieu of the 2 layers of 100g CSM.
Wet out the CSM thoroughly with the coupling coat resin and ensure that all air is removed from the reinforcement, that it is well wetted through and that the reinforcement is conforming to all the contours of the mould, particularly any tight corners.
Uni-Mould Tooling Coupling Coat should applied to cured Uni-Mould Tooling Gel Coat and then be reinforced with Uni-Mould Tooling Resin as per the guidelines for those products.
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.
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
The Uni-Mould Coupling Coat can be backed up with tooling resin and CSM as soon as it is tacky and up to 48 hours later. The time for the resin to become tacky varies depending on catalyst ratio and ambient temperature but typically we would expect around 2hrs after application if using 2% catalyst in a typical 20°C ambient temperature.
