To figure out how to melt asphalt onto stainless steel coupons so that it is not easily scraped off to mimic the the difficulty of getting asphalt off of the client's tools
Date Run:
06/02/2023
Experiment Procedure:
The convectional oven was preheated to 330 degrees F, in order for the asphalt to hopefully melt without its rubber content being burned off. Meanwhile, three stainless steel coupons were chosen. In the fume hood, dry asphalt rocks were set on each coupon. The coupons were then put in the oven and were baked overnight.
Trial Results:
The rocks of asphalt did not melt onto the coupons overnight in the oven. They were still solid, and while they had adhered a little bit to the coupon, they were easily scraped off.
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Conclusion:
Baking the asphalt onto the coupons in the convectional oven will not work to melt the asphalt onto the coupons. Additional testing strategies needed.
