Sherwin, Inc. is pleased to introduce two new products:
TWIN KDS PANELS
Sherwin Incorporated has introduced new penetrant test panels, known as Twin KDS Panels. They have induced defects of known size and depth.
The panels were designed specifically as a realistic means for complying with the ASTM E-1417 requirement that in-use penetrants be compared side-by-side to new, unused penetrant.
Twin KDS Panels give accurate, reliable information not obtainable by referring to impressionistic verbal data, or to nonfluorescing photographs.
Manufactured with a proprietary, patent pending process that controls crack size and depth, Twin KDS Panels are the best means available for complying with the ASTM E-1417 requirement. At the same time, they are similar to PSM-5 Panels in that they are rugged and relatively inexpensive when compared to other test pieces, such as NiCr Panels. With a base metal of stainless steel, Twin KDS Panels withstand the rough handling and rigors of daily trips down the penetrant line.
A feature not shared with PSM-5 Panels is ease of cleaning between tests, complying with ASTM E-1417, 7.8.3.1. A simple 30-minute soak in isopropyl alcohol clears the induced cracks of residual penetrant.
There are two Twin KDS Panel models to choose from, depending on sensitivity monitoring.
| MODEL WW | For use with water-washable (Method A) penetrants |
| MODEL PE | For use with nonwater-washable (Method B, C & D) penetrants |
WATER-BASED FLUORESCENT PENETRANTS: WB-100 AND WB-200
Sherwin Incorporated is the first manufacturer to offer water-based penetrants approved under MIL-I-25135 and listed on the QPL AMS-2644.
Sherwin WB-100 and WB-200, Level 1 and 2 penetrants respectively, may be used in place of any conventional Level 1 or 2 water-washable fluorescent penetrant, and with any QPL-approved developer, except water-soluble.
WB-100 and WB-200 have special advantages. Made without petroleum solvents or oil, their base ingredient is water; nonpolluting, inexpensive, and renewable. Free of petroleum distillates, they biodegrade readily and are more likely to be accepted by sewage treatment facilities.
WB-100 and WB-200 can be purchased in ready-to-use form or as a concentrate to which the user adds water. When purchased as a concentrate, freight charges and storage requirements are greatly reduced.
Both penetrants have excellent "self-developing" properties which, when conditions permit, eliminate or reduce the need to use a developer. WB-100 and WB-200 are a step forward in the evolution of penetrant technology. Contact Sherwin Incorporated or one of its representatives for additional information.
