QuikClot has been reformulated to minimize the heat created during the clotting process (they swithced from zeolite to kaolin)
Just for completeness, there are still second-generation zeolite-based QuikClot products that you may find out there, such as QuikClot ACS+, QuikClot 1st Response, QuikClot Sport, and QuikClot Sport Silver. I don't recall ever hearing of any heat issues with second-gen QuikClot products.
Products like QuikClot Combat Gauze and QuikClot Emergency Dressing are the newest kaolin-based products.
