Supreme 18TC maintains high bond strength properties even when exposed to hostile environmental conditions, including high/low temperatures. It bonds well to a wide variety of substrates including metals, composites, ceramics and plastics. This compound offers a tensile lap shear strength of 2,200-2,400 psi, a tensile strength of 6,000-7,000 psi, a t-peel strength of 5-10 pli and a compressive strength of 22,000-24,000 psi.
Significantly, Supreme 18TC is a one part system that requires no mixing. Its working life is essentially “unlimited”. It requires heat curing for 60-90 minutes at 250-300°F. A post cure of a few hours at 350°F will optimize performance properties. Supreme 18TC features a low shrinkage upon curing, 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.
