One Part Epoxy Adhesive Has Ultra Low Thermal Resistance

Master Bond Supreme 18TC is a single component smooth paste epoxy adhesive. Formulated with a blend of special thermally conductive fillers, this system can be applied in bond lines as thin as 10-15 microns. It offers an exceptionally low 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)]. Heat transfer capabilities are outstanding. It passes NASA low outgassing requirements and can be used in applications in the aerospace, electronic, optical, specialty OEM and cryogenic industries.

Supreme 18TC maintains high bond strength properties even when exposed to hostile environmental conditions, at both high and low temperatures. It bonds well to a wide variety of substrates including metals, composites, ceramics and plastics. It has a high strength profile consisting of tensile lap shear strength of 2,200-2,400 psi, tensile strength 6,000-7,000 psi, t-peel strength of 5-10 pli and a compressive strength of 22,000-24,000 psi.

As a one part system, it requires no mixing. Its working life is essentially unlimited. To obtain optimal performance properties, heat cure for 60-90 minutes at 250-300°F followed by a post cure of a few hours at 350°F. Supreme 18TC features low shrinkage, a low CTE and a high degree of dimensional stability. This system is also a reliable electrical insulator.

Supreme 18TC is designed to withstand thermal cycling and shock. It is serviceable over the wide temperature range of 4K to +400°F. This formulation is available for use in a variety of standard packaging options in sizes ranging from ounces to gallons.
