Why is epoxy not hardening?

The main reason is caused by inaccurate measuring two ingredients: resin and hardener, or not mixing it thoroughly. The most common sticky problems are: Tacky, Sticky Resin: the problem occurs when two components – A and B are measured and mixed inaccurate or curing in cold temperatures.

What happens if you don’t put enough hardener in epoxy?

Off ratio: Too much or too little hardener will affect the cure time and thoroughness of the cure. Remove epoxy. Do not apply additional material over non-curing epoxy. DO NOT add extra hardener for a faster epoxy cure!

Why is my UV resin still tacky?

Like most UV resins it’ll be tacky after only curing for a few minutes. That’s normal since UV resins harden fast but take some time to fully cure. It’s because it’s overheating while curing. Doing it in thin layers or curing it slowly (weak light) will greatly reduce this problem.

What is the difference between hard and soft resin?

Hard epoxy resin cures hard like a piece of plastic. Soft Resin cures soft like a silicon, it feels soft even after curing. UV Resin will not dry until it is cured under UV light.
