RC-29 Post-Emulsifiable Penetrant – Level 1

RC-29 is a low sensitivity, nonwater-washable fluorescent penetrant. RC-29 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-29 is formulated especially for the pre-wash process using Sherwin Inc’s ER-83A Hydrophilic Emulsifier. Most RC-29 is removed easily by the mechanical scrubbing of the wash, thus, reducing heavy reliance on an emulsifier, and insuring that flaw entrapped penetrants are less likely to be diluted or displaced.
