Hi, anyody can help me?
how to determine the new resin/hardener ratio when liquid epoxy resin has been loaded with intert fillers to form a putty? first case is when hardener is neat, and second case is when hardener also has been filled with inert loads.

Thanks!

Mmmm, no... I use talc all the time. The ratio stays the same. If it's a 2:1 ratio, it doesn't matter how much talc you add, the ratio of resin to hardener stays at 2:1. If you have 1000g of resin, you need 500g of hardener, no matter how much talc you added. You can add 2kg or 5kg of talc, you still have 1000g of resin and need 500g of hardener.
