Ardrox 9813 is a high-sensitivity fluorescent penetrant (Level 3 per AMS 2644) for post-emulsifiable applications, ideal for non-destructive testing of metallic components. It provides sharp indications with exceptionally low background and excellent UV and temperature stability. Suitable for spray, immersion, brush, and electrostatic application.

Compliant with AMS 2644 (Type I, Methods B, C, D) and EN ISO 3452-2, approved by CFM International, Pratt & Whitney, SAFRAN Group, Rolls-Royce, and SNECMA.

Used with Ardrox 9881 (hydrophilic emulsifier) and Ardrox 9D4A (dry powder developer), it ensures reliable inspection results. Non-corrosive on common metals; compatibility tests recommended for plastics and rubbers. Store between 10°C and 40°C, away from heat sources.
