Epoxy resin is a polymer that forms a cross-linked matrix when cured. Epoxy is different from polyester in that it has an epoxide group on one of its components, which gives it the ability to form covalent bonds between the two monomers.
As you might have guessed, these bonds make epoxy materials very strong. In addition to being strong and durable, they’re also resistant to many chemicals and solvents (which makes them a great choice for industrial applications), as well as incredibly flexible and elastic.
It’s important to note that there are two types of epoxy resins: polyether and polyester. Polyether-based epoxies are typically used for adhesives because their lower viscosity allows them to penetrate gaps more easily than polyester-based ones do; however, they don’t cure as quickly or completely at room temperature—but since this isn’t usually an issue when working with something like fiberglass cloth or carbon fiber fabric, using a polyether resin will save time and money without sacrificing quality or performance!
Can I mix different brand resin?
Yes, you can mix different brands of epoxy resin. It’s not unusual for artists to mix epoxy resins, especially if they are working on a large project that requires more epoxy than they have in their possession.
Epoxies are made from the same building blocks as all other adhesives: polymers (long chains of molecules) and solvents (which dissolve one or both ingredients).
There’s no reason why these two ingredients can’t be mixed together if they’re compatible with each other. You’ll find this fact consistently mentioned in every manufacturer’s instructions regarding mixing epoxy resins—and it’s true!

What will happen if I pour a second coat of epoxy resin using a different brand?
If you use a different brand of epoxy resin, there’s a good chance that it won’t bond to the previous layer and will leave an uneven surface.
Depending on how much time has passed between application of the first coat and application of the second, some layers may not cure at all.
In addition to leaving bubbles and cracks in your coating, using two different brands could also cause them to bubble up.
Can I mix 2 different resins together?
you should never mix two different resins together. Your best bet is to use the same brand resin.
It’s important to note that mixing different types of epoxy resin can cause problems with curing time, strength, and adhesion.
For example, using a high viscosity epoxy with a low viscosity epoxy will result in poor coating properties due to thickening during cure caused by incompatible cross linking sites between the two types of epoxies being used (more on this later).
Can I mix epoxy resins?
The short answer is yes. However, this depends on what kind of project you’re making and how much time and effort you want to spend on it. The longer answer definitely involves more details than your simple yes or no question deserves!
How do I know which brands are made from the same resin formula?
In order for two epoxy resins to be compatible with each other, they must have been produced by a company that uses the same manufacturing process and raw materials in their production facility.
Companies such as West System, Devcon/Devcon2 (US), Loctite (US), LePage (Canada) will always produce compatible products due to their common origins. Epoxies from companies like Loctite or Gorilla Glue may not be as consistent because they’ve changed manufacturers over time without changing their manufacturing process signatures or suppliers – so don’t assume anything!
Can I mix old and new resin?
- Yes, you can mix two different brands of epoxy resin.
- If you’re using hardener, try to use the same brand of hardener as the resin. However, if necessary, you can mix two different types of hardener with each other (for example: West System 105 epoxy resin and Devcon 2-part urethane).
- Since you’ll be mixing both resins together in one batch (rather than adding some old resin to a new batch), the ratio of mix will be based on volume rather than weight (how much resin is used per gallon). Because this is more difficult to measure than when using a scale for weighing out ratios of old and new epoxy resins separately before mixing them together into one batch, it’s best to have everything ready before mixing begins so that there aren’t any last minute adjustments needed or extra ingredients added at the last minute!
Can I use any hardener with epoxy?
It’s possible to use different brands of epoxy resin, but you have to stick with the same brand for both resin and hardener.
The mixing ratio is usually different from one brand to the next. For example, one manufacturer might make their resin at a 3:1 mix ratio while another uses 4:1. Mixing these two together could produce something like a 2:3 mix which will not adhere well with either product alone.
The best way to avoid problems with mixing different epoxies together is by using only one type on any given project (full strength or diluted). If you do decide you want to try out an alternate brand, just make sure they’re compatible before buying them!
How long do I wait between coats of epoxy?
So you are ready to pour the next layer of epoxy onto your project and wonder, “How long do I wait between coats of epoxy?”
The answer is simple: it depends on the brand of resin you are using. The cure time for each brand varies, so be sure to read the instructions that come with your product.
How do you apply the second layer of epoxy?
To apply the second layer, mix the two parts of resin and put them in separate containers. Use a brush or roller to apply both coats over the entire surface. You can also use an old toothbrush to get into grooves and crevices, but try not to leave any bristles behind.
As each layer cures (which takes 24 hours) wipe off any excess resin or bubbles with a paper towel. When you’re done, allow your project to cure for 72 hours before handling it; otherwise, it may get sticky or tacky!
When you’re ready to clean up after yourself, make sure you have plenty of ventilation—epoxy is made from nasty chemicals like epichlorohydrin that are bad for breathing! If your work area does not have adequate ventilation then wear a mask while working with epoxy resins because they do contain volatile organic compounds (VOCs).
Cleanup is pretty simple: just pour all your used materials down into a drain where they will dissolve away harmlessly into water—that includes a leftover solvent and adhesive remover too!
While mixing different brand resins is possible, it is not recommended. The biggest reason for this is that the chemical makeup of each brand of epoxy resin may be slightly different and you won’t know how your project will turn out until you have used it.
It’s better to stick with one brand throughout your entire project so that you aren’t surprised when it comes time for a second coat or if you need to use another brand later on. If you do need to mix brands during a project, be sure to wait at least 24 hours before applying any more epoxy resin to ensure proper curing.*
