A screening study was performed on a family of UV‐curable fluoro‐silicone polymers designed to coat aluminum. Solvent durability, adhesion, dimensional stability, and thermal oxidative stability were important physical parameters to control. An XVERT mixture experimental design was used to model the behavior of selected polymer formulations. A calibrated linear model showed excellent correlation with experimental data. The coefficients from this model were then used to predict and optimize the responses of the polymer formulations to specific requirements. It was shown that percent fluorination was a strong influence on the amount of solvent absorption and the level of thermal oxidative stability, while the amount of hydrocarbon‐based alcohol was shown to be necessary for adhesion to aluminum and a post cure polyurethane top coat.
