Adaptive speckle imaging interferometry (ASII):New technology for advanced drying analysis of coatings

摘要

In this work a new optical technology,ASII,is presented,for the study of film formation from all kinds of dispersed systems,such as latexes,emulsions or solvent-borne suspensions.Various film-forming products have been investigated,including water-borne coatings,on various types of substrates.A wide range of information can be extracted such as objective drying times (dust-free,dry-hard times,etc) or mechanism taking place,thereby offering new possibilities to analyse film formation from complex colloidal systems.
