We are trying to formulate stone epoxy coating with curing time less than one hr without yellowing at cost ~ of 200 per kg. I request any one of experts in this field to suggest suitable hardener. It is to be used on backside of the stone so the price is competitive in the market

Hello,

maybe this overview will help you with the selection of the appropriate hardener. Generally speaking (aliphatic) amines tend to cause yellowing. You should avoid them.
