The epoxy will not cure without the hardener. The hardener is what causes the epoxy to harden and cure. If you don't add the file, the temperature of the epoxy is important for it to cure properly. Only when mixed with an epoxy hardener can they cure properly.
If applied to a floor without the hardener, the resin would remain almost liquid indefinitely and could not be transformed into a durable flooring system. It usually takes about 72 hours to fully cure the epoxy. Whatever the drying time, the resin should be allowed to cure completely before attempting to move or sand it. If the epoxy is not allowed to sit until it is fully cured, your project will be prone to surface contamination.
Epoxy resins alone are very stable fluids with a relatively long service life. Accurately measuring and mixing well is essential to ensure that the epoxy resin cures properly. If you have an epoxy resin without a hardener, it simply dries as soon as water comes into contact with it. The ratio of resin and hardener varies from product to product, so read carefully the instructions on how much to use before mixing them.
If none of these solutions work, it is possible that the resin has expired or is contaminated in some way. It's likely that the sticky resin is because you didn't mix the resin and hardener well the first time, so be sure to pay special attention to mixing it well this time. As nouns, the difference between resin and hardener is that resin is a secretion of viscous hydrocarbons from many plants, particularly coniferous trees, while hardener is one that, or what, hardens. In most cases, the reason why the resin bends is due to the fact that the resin needs more time to cure.
These attributes occur due to the chemical reaction between the epoxy resin and the curing agent. Start by pouring 15 oz of resin into the measuring cup, followed by 15 oz of hardener, for a total of 30 oz. However, if there is too much hardener in the resin, it can cause problems such as cracks or bubbles. One possible reason why the epoxy resin is separating is that you didn't mix the hardener and resin correctly.
But if you don't use a hardener, will this still happen? The answer depends on the type of epoxy resin and how quickly it cures under ambient conditions (room temperature). If you are wondering if epoxy can be used without the hardener, then no: it will not harden or cure properly. The main reasons why your epoxy resin is flexible and soft are reduced to insufficient curing time, improper proportions of base resin and hardener, not mixing well, pouring resin too thin, expired or compromised, and moisture into your epoxy before curing, resulting in an elastic and flexible epoxy resin.
