| Résumé : |
Improving dirt pickup resistance especially in waterborne coatings is critical to future coating innovations. This review article focuses on the development of a coatings with improved dirt pickup resistance, with seems to be continues important goal in the coatings industry. The basic demand for this is due to the growth in "softer" elastomeric wall and roof coatings which demands low-VOC formulations and with traditional emulsions it results in tackier coatings due to reduced glass transition temperatures (Tgs). If we consider the current scenario of Asian continent, there are a huge number of high-rise commercial buildings constructions are planned, which is driving the need for coatings that are easier to clean and maintain.
Different processes of emulsion preparation such as post (room temperature) crosslinking and inorganic organic hybrid emulsion, which facilitate the cleaning of coating by water are been discussed. It also draws a brief idea on the possible applications of the same with different paint formulations.
This paper explains the terminology Dirt Pickup Resistance, laboratory test method to measure the same, newer challenges for Paint industry regarding DPUR & how the DPUR fora paint can be improved. |
