Glad to see the papers on ratios,mixes etc confirm my hands on experience.I have stated from the beginning 10% epoxy is impossible with our limited tools at home.I have stated in the past,which is better,10% dry epoxy mix or 20% with better wet out.The papers seemto say 20% is AOK.
Cameron the carbon black ratio is way too high.Unscientific ratio:add to taste or its black enough.
I was hoping for a Home Depot mix.Playsand,filter sand or aggregate,graded sandblast sand etc,for simple easy to obtain mixes.To dupe the big guys,impossible,at least on ratio.
De-Gassing 7% German beers presently;conclusions,7% Alcohol is obtainable in beer mixes,not in epoxy.Outgassing is smelly,refrane from smoking or other sources of ignition.
