Abstract
The paper presents a description of acrylic-based polymers used in civil engineering for concrete protection. Some information on chemistry and properties of the acrylic coatings is included together with current trends in coating technology. Moreover, the paper shows test results, that is barrier properties and SEM observations of a commercial elastic acrylic-based polymer subject to artificial weathering for 1000h. The studies showed that the weathering did not change carbon dioxide permeability of the tested coating and its influence on water vapour permeability of the material was also very small. The test results show that an assessment of coating performance based only on barrier properties is not enough.
Highlights
In the middle of XX century the first acrylic water-borne emulsions were developed
Water-borne acrylic coatings are known for some sought-after properties, such as very good weathering resistance and toughness, these types of coatings find a wide range of applications in civil engineering
The elastic acrylic-based coating was tested for 1000h, i.e. 126 cycles in a weathering chamber according to ASTM G 154a [10]
Summary
In the middle of XX century the first acrylic water-borne emulsions were developed. Later on, a wide range of modifications have been made in order to produce durable coatings. The obtained polymers can be used to produce two-component coatings containing water-borne acrylic and a crosslinking material used as a hardener. Water-borne acrylic coatings are known for some sought-after properties, such as very good weathering resistance and toughness, these types of coatings find a wide range of applications in civil engineering. They are a very good alternative for solvent-born systems keeping in mind safety of workers and environment protection. In order to accelerate the process, coalescing agents are added These volatile solvents optimize the coalescence of the particles. The most effective coalescing agents are partially watersoluble coalescing agents [1,2]
