Abstract
This study focus on influence of different drying and annealing conditions on the mechanical properties and film formation of the produced paint which is based on a novel hydroplasticized polymer dispersion. Two different coalescing agents with different polarity and a neat sample with two different thicknesses were used in order to study the influence of coalescing agent’s polarity, thickness and the binder on the mechanical properties and film formation of the samples. Pendulum hardness test, AFM, FTIR, water uptake, and tensile strength test were used to study early service life and mechanical properties. The hydrophilic coalescing agent was most effective at lower/room temperatures and lowers relative humidities and lead to a fast... (More)

Pendulum hardness test, AFM, FTIR, water uptake, and tensile strength test were used to study early service life and mechanical properties. The hydrophilic coalescing agent was most effective at lower/room temperatures and lowers relative humidities and lead to a fast hardness development but E-modulus and strength development was fastest at higher relative humidities. The hydrophobic coalescing agent was most effective at higher temperatures and lead to a fast hardness, strength, and E-modulus development, different relative humidities had no influence on mechanical property’s development. The neat sample had fastest hardness development at higher temperatures and lower relative humidities. The degree of film formation was higher at higher relative humidities and temperatures and Samples generally had a lower water uptake regardless of coalescing agents. A thicker sample leads to a longer hardness development and harder sample compared with the thinner one. AFM and FTIR couldn’t contribute to some new information in this study where the FTIR was not accurate to scan the self-crosslinking development during film formation, and the non-contact mode used during AFM was the wrong method.

The purpose of the AkzoNObel from this master thesis was to study the influence of the different drying conditions on the film formation and mechanical properties of a latex dispersion in order to produce a more resistance paint that can be used in all over the world.
