Chemical Activation – Chem Cure
Chemical Activation – Chem Cure Recently, we’ve been doing experimentation on ways to enhance viscoelastic stiffness and bond in gum natural rubber thereby minimizing flow and/or sag. Sometimes one needs to assemble a thick section of gum rubber by layering up four or more 1/4″ plies of gum rubber to 1″ thick or heavier. In laboratory trials, we have found …
