Bt-epoxy is a special kind of glue that people use to stick things together. It's made out of something called epoxy and chemicals called bisphenol A and F (BPA and BPF). Epoxy is a type of material that is strong and sticks to things very well, so it is a great choice for fixing things like broken dishes or making arts and crafts. However, it can also be dangerous because BPA and BPF can be harmful for people's health if breathed in or touched for long periods of time. To be safe, wear gloves when you use bt-epoxy and make sure to use it in an area with good ventilation so that you don't breathe in the fumes it gives off when it's drying.
