Sherwin HM-707 Fluorescent Water-based Penetrant Level 4

HM-707 is an ultra sensitive, last acting, self-developing, water washable fluorescent penetrant. HM-707 resists over washing, is low in sulfur and  halogen, heat stable, and has a high flash point (368°F). OSHA Class IIIB material.

HM-707 qualified to the stricter requirements of MIL-l-25135 D & E. Sherwin Incorporated recognized early the need for high flash point, highly stable nonvolatile, low toxicity penetrants.

Special Features:

Where ultra-sensitivity is essential and water washabi|ity is preferred, HM-707 is recommended. It should be noted, however that HM-707 is more expensive and more viscous than conventional petroleum distillate penetrants. Also,before using on difficult surfaces, the acceptability of background fluorescence should be ascertained.
Containing no petroleum distillates or light oils, HM-707 is biodegradable, and disposal authorities are more likely to accept its waste water than the waste water of conventional penetrants.

HM-707 is a proven product with the following advantages.
1. Reliable, ultra-sensitive performance on smooth surfaces.
2. Clean, relatively odorless product and vapor-free atmosphere.
3. Accepted as low-toxicity product by health authorities.
4. Biodegradable; effluent more readily accepted by sewage treatment officials.
5. Excellent electrostatic spray capability.
6. Special feature - does not contain petroleum distillates.
7. Use without developers where specifications permit.
 

HM-707 meets all military and applicable commercial specifications. Full conformance certification complying with MlL-STD-
6866 and other applicable governmental and commercial documentation specifications are provided with each shipment.
