LEECAST 38-191 is a proprietary two-part epoxy adhesive and encapsulating compound. It has been used extensively for potting lead wires in UL-listed commercial gasoline pumps. LEECAST 38-191 has exceptional chemical resistance, especially in respect to gasoline, various gasoline alcohol additives, and other aggressive organic solvents. It also features fast room temperature cure and excellent adhesion to a variety of wire coatings and other substrates. It is formulated with enough thixotropy to inhibit sag on vertical surfaces and self-leveling when applied in a bead on horizontal surfaces.

METHOD Cylindrical specimens of LEECAST 38-191 were exposed to saturated vapors for a period of 168 hours. Following these exposures, the samples were placed between two parallel plates and crushed with a compression-testing machine having a crosshead speed of 0.1 in/min. The load was applied perpendicular to the axis of the cylindrical samples and the compressive force required to crack and break the specimens was recorded. RESULTS. The resistance to crushing following sample conditioning was higher than 85 percent of the As Received value.
