I know someone here has used the anti-scaling paint when heat treating and I have a question about application. Steel being heat treated is AEB-L 1/16" thick Tried dipping a small blade and coating was twice the thickness needed minimum Second blade was coated four times with a foam brush. Both were allowed to air dry for at least 24 hours before hitting the furnace. Both blades were as black as the night when the coating fell off in the quench tank. Just a little decarb to say the least but luckily no grinding before heat treating so the damaged layer will hopefully be gone by the time shaping is done Thinking maybe I should bake the coating before putting in the furnace? Did a little research on the brand I chose ATP-641 and it appears to be a love hate relationship, some say it works and others like me end up with heavily blackened blades when working stainless. will have another batch later this week and plan on four coats to build up the thickness, pre-heating the steel to help burn off moisture and speed up cure time. Plus I might add in a step in the heat treating process of 250F for 10 minutes to reduce any moisture in the coating that could possibly be causing cracks and exposing the steel to the air. Anyone have any other ideas or suggestions (foil wrap) yes I have that as well but wanted to try out the paint. Going to experiment with using it to form a hamon in a 1095 blade this weekend as well.
