RC-50 is a medium-high sensitivity, nonwater-wash fluorescent penetrant. RC-50 is a general use material – high flash point, resistant to over-washing, self-developing where specifications permit, and relatively low viscosity. Excellent electrostatic spray capability. RC-50 is formulated especially for the pre-wash process using Sherwin Inc’s ER-83A Hydrophilic Emulsifier. Most RC-50 is removed easily by the mechanical scrubbing of the first wash, thus, reducing heavy reliance on an emulsifier, and insuring that flaw entrapped penetrants are less likely to be diluted or displaced.
