Product Overview
For regulated safety signage — egress route marking, fire-equipment signs, photoluminescent stair nosings — the pigment must meet quantitative afterglow requirements, not simply glow. Specifications reference DIN 67510 luminance decay thresholds (measured at 10, 30 and 60 minutes after a defined excitation) and ISO 17398 classification of safety-sign performance. High-brightness yellow-green strontium aluminate grades are chosen for this duty precisely because their emission peak near 520 nm matches maximum dark-adapted eye sensitivity and their decay curve clears the classification thresholds with margin — provided the sign builder uses sufficient pigment loading and film thickness, since measured sign performance depends on the whole construction. Manufacturers listed here supply signage-grade powder with batch decay curves, excitation-spectrum data and formulation guidance for rigid signs, aluminum laminates and solvent-borne inks, supporting downstream certification testing of finished signs.
