Engineering Adhesives PERMABOND ET5164Two-Part Epoxy Provisional Technical Datasheet Features & Benefits Excellent adhesion to stainless steel i EU Food Contact 10/2011 compliant t FDA 175.300 compliant High shear strength Description PERMABOND® ET5164 is a lightly thixotropic, 2-part epoxy adhesive designed to be compliant to both FDA 175.300 and EU food contact regulations 10/2011. ET5164 is designed primarily for bonding of stainless steel in food contact applications, however it will bond a variety of other substrates including steel and aluminium. Typical Physical Properties of Uncured Adhesive Graph shows typical strength development of bonded aluminium components. Curing at 60°C improves the crosslinking and results in higher final strength values. Lower temperatures will result in a slower cure. Hot Strength Typical Curing Properties Mix ratio by volume Typical Performance of Cured Adhesive Shear strength* (ISO4587) Cured 1 hour @ 60°C *Strength results will vary depending on the level of surface preparation and gap. Aluminium Stainless Steel Fully cured specimens conditioned to pull temperature for 30 minutes before testing at temperature. ET5164 can withstand higher temperatures for brief periods (such as for paint baking and wave soldering processes) providing the joint is not unduly stressed. The minimum temperature the cured adhesive can be exposed to is -55°C (-67°F) depending on the materials being bonded.
