Kohesi Bond KB 1040 CTE-LO is an exclusive two component epoxy system suitable for bonding, sealing, coating and encapsulation applications. It has a favorable 10:1 (Part A: Part B) mix ratio by weight. Remarkably, it offers extremely low coefficient of thermal expansion (CTE) and is capable of passing NASA low outgassing test. The optimal cure schedule is an overnight room temperature set-up followed by a heat cure at 70°C – 90°C for 3 – 5 hours. However, speedy cures are achievable with a straight heat cure as well at elevated temperatures.

KB 1040 CTE-LO can withstand extreme thermal environments down to cryogenic temperatures. It offers an extensive serviceable temperature range of 4K (-269.15°C) to +120°C. It is a phenomenal adhesive that offers outstanding physical strength properties and dimensional stability. KB 1040 CTE-LO adheres well to a wide variety of substrates including metals, ceramics, most plastics and glass. In addition to superior electrical insulation and thermal conductivity, it also offers astounding chemical resistance to a variety of fuels, oils and water. Part A has an off-white color and Part B has a clear color. Owing to its vacuum compatibility and exorbitantly low CTE, KB 1040 CTE-LO is widely used in electronics, aerospace, optical, semiconductor and various OEM applications.
