LK 31-73
LK 31-73 is a ready-to-use suspension of fluorescent magnetic powder in hydrocarbons for wet magnetic particle testing.
About the LK 31-73
LK 31-73 is a ready-to-use suspension of fluorescent magnetic powder in hydrocarbons for wet magnetic particle testing. The fluorescent pigment used enables high contrast under UV light. Due to small size particles, this powder is very sensitive and particularly suitable for surfaces with low roughness. LK 31-73 is a product with low sulphur and halogen content, according to standards. Intended NDT method: fluorescent magnetic particle inspection, wet method. CGM states compliance with EN ISO 9934-2, ASME V Art. 7, ASTM E709, ASTM E1444, AMS 3046, AMS 3045, AMS 2641, PMUC (certificate of compliance upon request). Published packaging: 10 L cans, 400 ml spray, 500 ml spray.
