LORD 3170 is a two component epoxy adhesive system designed to bond a wide variety of substrates including glass, metals, reinforced plastics, ceramics and foam materials for cryogenic applications. This advanced material has minimal outgassing suitable for aerospace applications and it will provide high strengths even in cold environments. The appearance of 3170-A resin is a milky white liquid and 3170-B hardener is an amber color liquid. Thoroughly mix LORD 3170 equal parts of hardener and resin by volume until uniform in color. The color of the mixed adhesive will be a light amber paste. When mixing, it is strongly recommended to no whip excessive air into the adhesive.
Heat buildup will occur due to exothermic reaction between the two components causing the working time of the adhesive to be shortened. When applying LORD 3170 Adhesive, it is important to remove grease, soil, oil, and other contaminates that may be on the surfaces being bonded. The thickness to apply for general use is roughly between .05 to .07 mm. When bonding foam insulation materials, the recommended thickness is .25 mm. At 24 degrees Celsius, the product will have a working time of approximately 2 hours. Once set, time to handling strength will be 24 hours. Parts that bond well and don’t need excessive clamping will have maximum adhesion. Clamping pressure may squeeze too much adhesive from the bond causing failure to bond.
LORD 3170 will be fully cured and have full strength in 4 days at 24 degrees Celsius. A 1 hour cure is possible to achieve if needed by heat curing the adhesive at 100 degrees Celsius. Use hot water and detergent or ketones to remove any excessive adhesive left on the tools or on the assembly before it cures. Once it cures, LORD 3170 will be difficult to remove. Heat the adhesive to 204 degrees Celsius to soften it up, this will allow an easier removal of the adhesive. Some commercial epoxy strippers may be used with some success.
This innovative material is not to be used in household applications and it is not suitable for consumer use. When handling any type of adhesive or sealant, it is important in understanding the safety precautions and proper application methods. When stored in its unopened container, between the temperatures of 21 and 35 degrees Celsius, LORD 3170 Adhesive has a shelf life of two years from the date of manufacture. If more handling instructions are needed, take a look at the LORD 3170 MSDS for all of your safety needs.
