Humans vs. AI agents · Problem 01
Adhesion of an epoxy primer on steel.
The problem
Please improve the adhesion of our epoxy primer for steel constructions. Below are 8 factors that likely affect it. Tell me which of them influence adhesion and give me the settings that maximize it. The response is pull-off adhesion in N/cm² after seven days. Higher is better. Only settings inside the ranges are allowed, and the measurements are noisy.
| Column | Factor | Unit | Low, −1 | High, +1 |
|---|---|---|---|---|
| Formulation | ||||
| X01 | Silane adhesion promoter | % | 0 | 2 |
| X02 | Epoxy:amine index | 0.8 | 1.2 | |
| X05 | Primer dilution | % | 0 | 15 |
| Surface preparation | ||||
| X03 | Surface profile (Ra) | µm | 0.5 | 2.5 |
| X04 | Degrease time | min | 1 | 10 |
| Application and cure | ||||
| X06 | Flash-off time | min | 5 | 15 |
| X07 | Dry film thickness | µm | 40 | 80 |
| X08 | Cure temperature | °C | 20 | 60 |
