IB2 Epoxy Infusion Bio Resin is low viscosity and optimized for high performance resin infusion applications, while it is compatible with all common fibre reinforcements it is particularly well paired with flax reinforcements to provide composite parts with a significantly reduced environmental impact.

Our bio resins are not compromised in performance but simply derive the same chemicals from plant-based sources. A key component of epoxy, epichlorohydrin, is manufactured using renewable plant-based Glycerol in place of petroleum-based propylene. Additionally, the raw materials going into our bio resins are co-products or waste products of other industrially important processes which means they do not compete with food sources or displace food-based agriculture. The resin component contains 38% plant based content. Once mixed with its hardener the overall plant-based content is ~31% which is amongst the highest in the industry.

IB2 is a high-performance bio epoxy resin suitable for use with a wide range of reinforcements including glass, carbon and aramid fibres as well as natural reinforcements such as flax and jute fibre. Its special low-viscosity formula is particularly suitable for resin infusion and RTM moulding processes. For hand laminating we have another Bio Resin, LB2, which has viscosity and cure profile better suited to hand layup processes.

Uncompromised mechanical properties compared with conventional ‘non-bio’ epoxy resins. Compatible with carbon, glass, aramid and natural fibres, Vacuum resin infusion / RTM. Sustainable Resins for Greener Products

Typical Uses

Having excellent mechanical and processing properties the IB2 Epoxy Infusion Bio Resin can be used for a wide range of uses including but not limited to:

Sports/recreational equipment - skis, boards, canoes, archery.
Motorsport – panels, aerodynamic elements, structural members.
Marine – hulls, foils, masts.
Wind energy – masts, blades, nacelles.

IB2 is the perfect choice for use in combination with our range of sustainable natural flax reinforcements from Eco-Technilin. Used together, these materials allow the development and production of greener products with significantly reduced environment impact. You can find our full range of flax fibres here: Natural Fibre Reinforcements

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 IB2.

Compatible Moulds

Uni-Mould Mould System
Epoxy Tooling Gelcoat
Epoxy gelcoat based moulds
Polypropylene and polyethylene sheet
Aluminium
Toughened Glass (eg. flat sheet manufacture)

Compatible Pigments

Epoxy Colour Pigment * (for vivid opaque colours)
CULR Pigment * (for vivid opaque colours)
Translucent Tinting Pigment * (for less vivid opaque colours)

Compatible Fillers

All dry filler powders

* With bold coloured laminates such as carbon fibre, the underlying colour of the fabric may still show through the pigmented resin, especially with thinner layers of resin over the underlying laminate.

Key Processing Information

Ease of Use: The resin has no unusual characteristics and offers good ease of use and reliable performance (follow SDS advice).
Odour: IB2 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 15 to 30°C although pot-life and cure time will be affected significantly. Recommended working at an ambient of 20-25°C.
Degassing: Not necessary in most cases. Simply mix and use.
Mix Ratio: Mix 'Resin' and IB2 Epoxy Hardener' 100:22 by weight. Use digital scales.
Mixing: Mix thoroughly by hand for at around 2 minutes.
Pot-Life: Pot life of 500g @ 20 °C is 85 minutes. Increasing ambient temperature and/or batch size can significantly reduce this time.
Exotherm (Over-Heating): 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.
Cure Time/Demould: At 20°C you can expect a typical gel time of 7 hours, and a demoulding time of 35.5 hours.
Pigments and Fillers: A wide range of pigments and fillers can be added to change the properties and appearance of Resin.

Resin and Hardener Crystalisaton

The Resin and Hardener is sensitive to low temperatures and if they get cold (either in storage or transport), it can crystalise; this does not damage the product at all and can be reversed by warming the product in its container with the lid securely in place. The longer it has been crystallised, the longer it will take to reverse. This can be achieved by sitting it directly onto a radiator, putting it into an oven on a low setting or standing the container in hot water.

As with many post-cure cycles for resins, the post-cure cycle for our EL2 and IN2 Epoxy Resins is not too sensitive and a range of different post-cure cycles will produce good results, specifically improved mechanical performance and elevated HDT/operating temperature. Post-curing parts that will be used at or exposed to elevated operating temperatures (such as vehicle bonnets/hoods in direct sunlight, engine-bay parts, car interior parts etc.) is strongly recommended to prevent distortion of the parts when they are put into service and experience these higher temperatures.

Where possible, parts should be post-cured still inside the mould to reduce distortion and improve surface finish (i.e. reduce 'print-through'). When post-curing parts in the mould, it is important to post-cure them without demoulding at all (i.e. don’t demould and then put them back into the mould) otherwise you can get some strange patterns on the surface where some areas are post cured in direct contact with the mould surface and others are not.

A simple and very effective post-cure cycle with the IN2 Infusion Resin (or EL2 Epoxy Laminating Resin) is as follows:

CYCLE #1 SUITABLE FOR MOST SITUATIONS

24hrs at room temperature
6hrs at 60°C

If you’re encountering any surface finish issues (faint print-through) then you can experiment with a slower 'ramp rate' which sometimes improves things:

CYCLE #2 SUGGESTED FOR SUBTLE IMPROVEMENTS TO SURFACE FINISH

24hrs at room temperature
2hrs at 40°C
2hrs at 50°C
5hrs at 60°C

If you need to push the HDT of the finished part higher then you could increase post-cure up to a maximum of 80°C as follows:

CYCLE #3 SUGGESTED FOR HIGHEST POSSIBLE HDT/OPERATING TEMPERATURE

24hrs at room temperature
2hrs at 40°C
2hrs at 50°C
2hrs at 60°C
2hrs at 70°C
4hrs at 80°C

These are all just suggestions. Most situations just call for option #1; 6hrs at 60°C. Many customers also find that they can dispense with the 24hrs cure at ambient and simply load newly infused parts into the oven to begin the cure however this is something that you would need to experiment with yourself. A cure at ambient temperature before post-cure is generally favoured with most resin systems.

Yes, but it's highly recommended to use specialist 'powder bound' chopped strand matt. This is because conventional chopped strand matt is 'emulsion bound' which relies on styrene and solvents in the resin to break the binding down. Epoxy does not have these solvents. As a result, specialist 'powder bound' chopped strand matt is needed as the powder binding is broken down by the liquid itself.

Most cured epoxy resins have self-extinguishing properties however none of our epoxies have formal 'fire rating' data because they're not designed as intumescent or fire retardant resins. The reinforcement you use will also have an impact on the fire retardancy of the finished product.

If you're specifically setting out to make fire-retardant parts I would suggest using a specialist intumescent resin - however, bear in mind that generally these resins will contain inert fillers which compromise their mechanical performance to some extent.

The maximum service service temperature of IB2 once a post cure is has been completed is 85°C. Full details on the post cure cycles can be found on the technical datasheet.
