PR-1538 is a high hardness potting and molding compound. It has a service temperature range from -70°F (-57°C) to 300°F (149°C). This material is designed for potting electrical connectors, molding electrical cables and mechanical parts, circuit board coating and/or electrical embedding compound. The cured compound is resistant to contact with water and oils. PR-1538 is a two-part, chemically curing polyurethane compound. It cures at room temperature to a tough, semiflexible, cold flow-resistant rubber. The material has very good electrical properties, especially dielectic strength and volume resistivity, in thin films.
The following tests are in accordance with PRCDeSoto International and MIL-S-8516 specification test methods.
