Bonding with Differing Coefficients of Thermal Expansion
We have a problem maintaining adhesion to two steel surfaces at divergent temperatures because of the response of materials to thermal conditions when going through heating and cooling cycles.
Question: We are using epoxy adhesives to bond steel substrates that are exposed periodically to both 150˚C and as low as 0˚C. Our problem is in maintaining adhesion to the two steel surfaces at such divergent temperatures because of the response of materials to thermal conditions when going through heating and cooling cycles. Do you have any suggestions?
