axtually i am trying to make coconut shell powder composite based cups. i have tried various reinforcing materials like accacia gum, gaur gum, starch but i didnot get good results as the composite was stcking to mold even after using mold release agent ( silicone spray) and even teflon sheets and i was not getting enough strength as it was breakig so i thought of using epoxy? please help me out of this problem
