| Résumé : |
Many commercially available coatings that have been used are subject to combined effect of exposure to sunlight, changing humidity, and hot and cold cycles experienced during weathering. In many cases, due to lack of maintenance, the paint gets deteriorated, and starts to peel. Also, in the past, lead-based paint was used as a primer for the coating systems applied to these steel structures. Peeling lead-based paint will eventually fall into and contaminate the soil, and require extensive environmental cleanup.
This paper will discuss a one-coat, high-build, lead-free, low VOC, self-priming coating that provides long term corrosion protection, low application costs, requires minimal surface preparation, and is easy to maintain. The system has been in use for over 50 years. Surface tolerant coatings, which can be applied over existing coatings with minimal surface preparation, provide a solution to these problems. |
