Kohesi Bond TUF 1820 AOHT is a noteworthy toughened, single component epoxy system that requires no mixing and offers an unlimited working life at room temperature. It cures in merely 60 – 70 minutes at 120°C and even faster at higher temperatures. TUF 1820 AOHT offers a sweeping serviceable temperature range of 4K (-269.15°C) to +200°C. This product can withstand severe thermal cycling and shocks even at cryogenic temperatures. Being a one component system, it provides ease of application and also adheres well to a wide variety of substrates including metals, ceramics, composites, most plastics and glass. It provides phenomenal bonding and physical strength properties, as well as dimensional stability. It offers a startling tensile lap shear strength of over 3,800 psi. TUF 1820 AOHT is a 100% solids and a reactive system i.e. it does not contain any solvents or diluents. In addition to superior electrical insulation, TUF 1820 AOHT also offers very good thermal conductivity. It has a gray color. It also extends first-rate chemical resistance to a variety of solvents, fuels and water. Owing to its high-caliber performance and ease of use, TUF 1820 AOHT is widely used in various other electronics, optoelectronic, aerospace and specialty OEM applications. PRODUCT HIGHLIGHTS Excellent thermal conductivity Cryogenically serviceable Stellar mechanical strength properties Outstanding dimensional stability Resistance to extreme thermal cycling Unlimited working life at room temperature TYPICAL APPLICATIONS Bonding Sealing
