Polymer Dispersions

The effect of mineral filler compounds on vapor permeability and hygroscopic properties of water-based polymer dispersions and the possibility of their use as decorative and protective material for stucco facades finishing was studied. According to Facade Protection Theory (H.M. Künzel), the assessment criterion was vapor permeability and water vapor diffusivity. The pairwise correlation of building physical properties of water-based polymer dispersions in the coordinates of Künzel's diagram clearly demonstrates that, in terms of hygroscopic, all the samples studied correspond to the low hygroscopic class, and in terms of vapor, they are close to high water vapour diffusion rate class.

The present study shows the optimization of mineral filler blends for use in water-based paints. The aim of the modelling is to evaluate the possibility of creating a model of prediction of the contrast ratio and brightness of the dry film, where the fillers that participate in the system are fillers used commercially by the paint industry. The differential of the use of the mixtures design, called Simplex, is that the predictions are made by carrying out a linear combination between the proportions of the mineral fillers and the response variables. The proposed procedure consists in generating a numerical model that can predict final paint properties depending on the concentrations of the mineral fillers (PCC, GCC and kaolin) used. As support for simplex mixture design, the methods of Partial Least Squares regression and Response Surface were used in the calculations of the models and in the visualization of the response variables.

Adhesion Work

The properties of coatings largely depend on the nature of the interaction of the film material with the substrate – the type of bonds between them. The degree of this interaction, associated with the nature of the paint and varnish material, mineral fillers and the nature of the surface to be protected, may be a criterion for evaluating the protective and operational properties. Therefore, an urgent scientific and practical task is to study the silicate fillers effect on the nature of adhesive interactions at the interface of water-based coatings with a steel substrate and to establish the relationship of adhesion strength properties with the thermodynamic adhesion work. It is shown that the adhesion strength in the paint systems for steel is significantly affected by the thermodynamic adhesion work, in which the dispersed component of the surface free energy makes the greatest contribution when the degree of filler content changes.
