Message:

Hi everyone. I´ve brought a 1 liter can of LATEX or Isoprene. My goal is to make some solid rubber parts. Now, my problem is how do liquid LATEX transforms into a hard rubber block? Until now, I only get thin layers of rubber, when the liquid is exposed to the air. In such conditions, It forms a surface skin isolating the liquid below. I´ve read something about hardeding LATEX using sulfur as a crosslinking agent.This is the old vulcanization method that also needs heat. Now, can anybody tell me how in detail this process of vulcanization could be done? I mean ideal temperatures, percentages of sulfur or any other reagents,procedures etc, etc... Thanks in advance
