Once cured, is this resin food 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.
Does this resin have a smell/odor?
In common with most epoxy resins, this resin only has a faint odor/smell when mixing and working with it. This is due to the fact that epoxies have little or no volatile content and so don't give off fumes or vapor. When in their liquid state the hardener side does have an ammonia smell whereas the resin is just faintly sweet smelling. Once fully cured, the finished part will be stable and odorless.
What is the proper disposal method for an unused or out of date resin?
Uncured resins are classed as dangerous goods and would need to be disposed of correctly. For domestic users, usually your local council recycling center 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Because cured resins are inert and safe for disposal it's often easiest to mix unneeded or out-of-date resin with hardener together to cure them. Once cured they can be disposed of with general waste.
Is post curing needed on finished part?
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.
What happens to the resin above the heat distortion temperature? Will the resin melt and flow again?
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.
Is it possible to do a elevated temperature cure with this resin (without removing the part from the mould)? What is the maximum temperature?
Yes, it is. The max temperature would be 60°C. At this temperature the resin will cure very quickly; see the datasheet for more information on cure times and post-curing.
What would happen if I get the mix ratio wrong?
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.
What can I use to clean epoxy off brushes?
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.
