Does epoxy resin dry in a closed tube?
Hello, I have a pipe that is a bit unstable and I want to stabilize it by pouring epoxy resin into it and letting it harden.
Is that possible? Does it dry properly? Does epoxy resin need air to "breathe" while drying?
Epox does not need air, it cures by a chemical reaction between resin and hardener.
Yes, since it is a reaction of part A and part B and no air, but only the relevant chemical components are required.
How large is the pipe and what material? The epoxy resin is a 2-K resin and does not need air or moisture to harden in the tube. It is a high-strength plastic, but if your part is stressed on bending, or bending, it only strengthens the pipe moderately. I would pour in a second thinner pipe or solid material, which can then absorb more forces.
