| Résumé : |
Covering sharp edges has always been a considerable challenge for the coatings industry. Existing coatings struggle to maintain a uniform layer of protection on a sharp edge throughout the curing process, especially those that have edges cut on steel. This lack of uniformity on sharp edges can compromise a coatings performance and lead to deterioration. Rust and corrosion along these exposed edges continues to be a significant issue, prompting a need for innovation in the coatings industry. |
| Note de contenu : |
- Fig. 1 : Maximising powder coverage at the edges is a challenge for both liquid and powder thermoset systems. Pull-back of paint during the cure cycle further exposes these sharp edges
- Fig. 2 : Example of line-coated parts at a customer trial, this time over primer, another instance of PPG's high-edge powder and its ability to overcome transfer efficiency and flow issues and build film
- Fig. 3 : 1000hr sait spray data on actual powder line-applied parts. Even on a large application line, using Envirocron, the improvement in edge film build is greatly improved based on this long-range test data
- Fig. 4 : These SEM images demonstrate Envirocron high-edge formulation's ability to cover highly ragged, burred edges
- Fig. 5 : Salt spray results fora standard powder formulation and one modified for edge-protection. Significant performance improvement is evident in the high-edge formulation when using Envirocron |
