ARC SD4i

Chesterton ARC SD4i is a sprayable, 100% solids ceramic-reinforced epoxy coating designed for extreme immersion service in corrosive and erosive environments. It forms a smooth, high-gloss barrier that resists chemical attack and microbiologically influenced corrosion (MIC).

Applied at 250–370 microns per coat, ARC SD4i performs in continuous dry temperatures up to 248°F and wet conditions up to 149°F. It’s ideal for flotation cells, hydrocyclones, slurry pipes, heat exchangers, and thickener tanks—extending equipment life with minimal downtime.
