strange catalytic reaction with 30 minute epoxy
Hi I also have had larger amounts cause a faster cure rate ! I since never mix much more than 1/2- 3/4 oz in one container. I use the paper pad mixing pallet for smaller amounts. But the 1oz epoxy cups for my larger amounts I clean and reuse the cups ! I clean the cups as quikly as possible with rubbing alcohal !or if it cure I pop it out. But the cups are cheep if your working on a large glue job and want fast mix and managable. I think the last batch of 50 was around $2 at our LHS . Just not expencive enought to break anyones bank!! also the cups have graduation marks in fractions of OZ or in CC .. just my $.02
