When the Resin (Part A) and Hardener (Part B) are mixed, they start to cure through a chemical reaction that produces heat. when left in too large a volume, this reaction can start to accelerate leading to premature curing and excessive heat. To avoid this issue, pour out the product soon after mixing into a larger working container. This spreads the volume out, reducing heat buildup. Additionally, it's best to start with a small batch. You can always increase the batch size if necessary.
