Vac Cast is an aluminium filled epoxy casting resin designed for high temperature tooling applications such as vacuum forming tools. Vac Cast cures quickly with minimal shrinkage and can be cast in quite large volumes. The system is highly polishable and very hard-wearing making it ideally suited to vacuum forming and other repetitive pressing/moulding applications.

The low mixed viscosity of this two-part epoxy system ensures very accurate reproduction of even the finest surface detail.

Typical Uses

  • Vacuum forming male tools
  • Platen press tools
  • Any cast moulds

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 Vac Cast.

  • Compatible Moulds
  • Condensation/tin cure RTV silicone rubber
  • Addition/platinum cure RTV silicone rubber
  • Polypropylene and polyethylene sheet
  • Compatible Pigments
  • Epoxy Colour Pigment * (for vivid opaque colours)
  • Translucent Tinting Pigment * (for less vivid opaque colours)
  • Compatible Fillers
  • All dry filler powders

* Although these pigments are technically compatible with Vac Cast, the already grey colour of the resin is likely to make it quite hard to pigment it to other colours in anything other than a dark shade.

Key Processing Information

  • Ease of Use
  • Suitable for professional and hobby use (follow SDS advice).
  • Odour
  • Vac Cast is almost odourless.
  • Safety Precautions
  • Wear gloves and goggles and work in a well ventilated area. Always read the SDS before use.
  • Ambient Conditions
  • Can be used from 10 to 30°C although pot-life and cure time will be affected significantly. For small or thin-section castings an ambient of 20-25°C is required.
  • Degassing
  • Not necessary. Simply mix and pour.
  • Mix Ratio
  • Mix Resin and Hardener 100:6 by weight. Use digital scales.
  • Mixing
  • Mix thoroughly by hand for at around 1 minute.
  • Casting Thickness
  • Block off sections to limit casting thickness to 75mm<
  • Pot-Life
  • 2-3 hours. Be sure to pour your casting(s) before this time.
  • Exotherm (Over-Heating)
  • Resin will heat-up whilst it cures. Once mixed, pour resin immediately.

Can’t find the answer you’re looking for?Ask our technical team a question.

Glass Bubbles can be added to most resins to reduce the density of the cured material. However, bear in mind that they will reduce the clarity of the GlassCast resin, making it more of a translucent 'milky' appearance rather than transparent.

100% solids epoxy resins, including this one, don't contain any solvents and so they don't produce any fumes during mixing, use or cure. There is just the faintest smell but, as stated, this is not fumes and so there is nothing really to consider in terms of density.

No, we wouldn’t suggest Epoxy Resins for lining a fuel tank. In general, epoxies have good resistance to petrol and many of the chemicals and additives found within pump fuel however the ethanol in fuel is known to cause problems over time and so specialist tank lining resins (often novalac vinylester based) should be used instead. One such product is GTS 1750 which is sold by Caswell Europe.

No, this epoxy in common with other epoxies does not attack expanded polystyrene

We have not specifically saught FDA (or similar) approval for this resin system so if you were to make these plates commercially then you would either need to make a plate using this resin system and then have it tested and approved safe for food use or use a different resin system that has specifically been approved for food use. Mixed and cured fully and properly the resulting plastic should be stable and non-toxic but testing would be required to prove this. Regarding being dishwasher safe; a dishwasher is a very harsh environment (abrasive, high temperatures, caustic) and so I think it would be quite hard on any resin system. By all means conduct your own tests but I would strongly recommend that a carbon fibre plate was not marketed as 'dishwasher safe'.

Although generally cured epoxies are non-hazardous, none of the products we have are certified food safe and thus we cannot recommend their use with food products.

We recommend Acetone. The brushes must be cleaned before the resin has cured. If you can’t get hold of acetone it’s also possible to use methylated spirits or neat alcohol.

In really simple terms you can think of 1kg of the Epoxy Resin as being 1L. If you want to be really exact (for example if you want to mix the resin and the hardener by volume and not by weight (which we don't recommend because it's unnecessarily complicated) then the relative density of the resin and the hardener, and the mixed product, can be found on the technical datasheet.

We can send any quantity of resin to Portugal. We would use a TNT Road service. To find the shipping cost for any item, simply add it to your basket and then click the 'Estimate Shipping' button on the basket page. The price will then be shown once you chose your shipping country (Portugal).

Unlike other resin systems such as polyester or vinylester, it's very important to get the mix ratios accurate with epoxies. If you get the mix ratio wrong by a small amount (let's say a couple of grams on a small mix) then the resin will still cure but the mechanical properties won't be quite as good as they would have been if the mix ratio had been exactly right. However, if you were to be out by anything more than a few grams then you might find that the resin would not be properly hard when cured and/or may have a tackiness to the finish. This would result in a much weaker repair and needs to be avoided by careful measurements.

Above the HDT of a resin system it will soften slightly and its mechanical properties will start to fall away however a thermosetting plastic (like epoxy) is NOT a thermoformable plastic so it will not start to flow again such that you could melt it out of your part. It's more likely to become slightly soft and then possible more brittle again before eventually starting to burn if you too the temperature high enough. It sounds to me like you need a thermoformable plastic (aka a thermoplastic) with a relatively low melting point. I'd suggest something like PCL.

An elevated temperature post-cure is not required for parts made with epoxy resin however, post curing parts will improve the mechanical properties of the resin (and therefore the part) and so if you have the means to do it then it's certainly recommended. One major advantage to post-curing epoxy is that you will raise the HDT (heat distortion temperature) of the part meaning that it's less likely to soften or distort in higher temperatures. This can be particularly important for parts like a vehicle panel (i.e. hood/bonnet) which could get very hot in the sun. Without a post-cure there is a good chance that the part would effectively post-cure itself 'in situe' when it's in direct sunlight which can cause the resin to soften, sink and then re-harden. When this happens to a fitted part it's likely to distort the surface finish. A part that had been post-cured prior to installation would not have this problem.

Epoxy resins have very little odour and so it's quite viable to use them indoors (i.e. in your house) without upsetting anyone. The resin is almost completely odourless and the hardener has an amonia smell which doesn't really carry or linger.

In this respect epoxies are very different to polyester and vinylester resin which has a very strong smell and cannot realistically be used indoors. As always, you should still follow safety precautions and ensure adequate ventilation of your work area.

Uncured resins are classed as dangerous goods and would need to be disposed of correctly. For domestic users, usually your local council recycling centre will have a disposal service for such chemicals or containers.

Because cured resins are inert and safe for disposal it's often easiest to mix un-needed or out-of-date resin and hardener together to cure them. Once cured they can be disposed of with general waste.

Epoxy is sensitive to low temperatures so we would not attempt to try and cure the resin at very low temperatures such as below 15 °:C. At those temperatures, the cure time will be lengthened considerably.

One of the most significant problems caused by low temperatures (much below 20°C) is that the resin will be considerably thicker which affects its ability to self-degas after pouring.

Also, curing epoxies are hydroscopic so the low temperature environment may well leave the resin vulnerable to absorbing moisture, especially if the environment is relatively damp or high in humidity as can be found in some outdoor workshops or home garages.

As a result, for best results we always recommend working in an environment that is 20°C or above.

The B stage of the cure is when the resin has cured enough to be firm but still tacky. When touching with a gloved finger, the resin should feel tacky but not leave any residue on the glove.

Vac Cast can be cast into tin/condensation cure silicones as well as addition/platinum cure silicones no problem.

No, Vac Cast is an opaque solid dark grey colour. Just to avoid any confusion, Vac Cast is used for making vacuum forming tools (moulds), not for the actual vacuum forming itself. The vacuum forming could be done using a clear sheet, like Lexan.
