The Teas chart, projecting three dimensional Hansen solubility parameters onto a triangular space. ‘Peak swelling’ region identified by Hedley [98] based on data from Stolow (see “Theoretical prediction of swelling” section) in grey, extended ‘peak swelling’ region based on different paint types identified by Phenix in light red. W = water, N = nitrogen containing solvents, K = ketones, Alc = alcohols, G-E = glycol ethers and esters, E = esters, C = chlorinated solvents, Ar = aromatics, Ali = aliphatics.
