- The delineation of phase separation of two very similar polyester resins is not achievable using characteristic ions from the resins, which occur a relatively high mass, and are not of sufficient intensity to provide good images. This paper presents a new multivariate analysis approach for the processing of ToF-SIMS data, developed at Surrey now formalised as open source software (mvatools.com; doi.org/10.1016/j.chemolab.2018.10.001) with 142 users worldwide, to achieve this. This work will lead to the development of self-stratifying systems for coil coating applications, and generated further funding from Becker Industrial Coatings.
