Source scope
Declared Primer 270–273; steel substrate for 271, steel/aluminum for 270/272/273; selected prepared convex edges.
Implementation in Prufi
Part preparation advises mechanically rounded sharp edges of approximately 1–2mm to reduce insufficient primer thickness. INFO below 1mm only, not an upper bound or coating certification. Local quarter-cylinder round with full-length shared generators and oriented tangency to perpendicular planes; opposite curved sheet-bend walls excluded. Stainless and unsupported materials remain unassessed.
