Well, my idea for reinforcement comes a little late. While you were assembling it, you could have inserted thinwall conduit into the PVC pipes so that outside the desk looked like all PVC but inside it had a hard stiff core of thinwall pipe in it. A 3/4 inch thinwall conduit fits nicely into a 1 inch PVC pipe. A 1/2 inch thinwall fits nice into a 3/4 inch PVC. Thus stiffening it up.
Epoxy is not one thing, it is a class of propolymers and polymers that epoxides. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins. So, their are organic epoxies, but the ones used in this case are inorganic.
