Supreme 18TC is a single-component epoxy adhesive that contains thermally conductive fillers. Can be applied in bond lines as thin as 10 to 15µm. Offers thermal resistance of 5-7 x 10-6 K•m²/W and a thermal conductivity of 22-25 BTU•in/ft²•hr•°F [3.17-3.61 W/(m·K)]. Reportedly maintains high bond strength properties when exposed to hostile environmental conditions, including high or low temperatures. Bonds well to metals, composites, ceramics and plastics. Offers tensile lap shear strength of 2,200-2,400 psi, a tensile strength of 6,000-7,000 psi, and a compressive strength of 22,000-24,000 psi. Is a one-part system that doesn’t require mixing. Requires heat curing for 60-90 min. at 250-300°F. A post-cure of a few hours at 350°F optimizes performance properties. Features low shrinkage upon curing, low CTE and high degree of dimensional stability. Is a reliable electrical insulator. Is designed to withstand thermal cycling and shock. Is serviceable over the temperature range of 4K to +400°F. Passes NASA low outgassing tests.
