You wanted someone from Loctite to add their opinion on the matter. Our official statement on expired material is that after the expiration date we can not certify the performance and/or quality of the material. Although most likely the material is g

Just a thought. What is the real shelf life of the past? Do manufactures low ball the self life to sell more paste. If the past is perfectly good one day before the expiration date is it still bad one day after I doubt it. Right or wrong I have seen

Hi Dave, J-STD-005 is the standard for solder paste requirements. I checked J-STD-006 for solder alloys fluxed and non fluxed and could not find any information on expired wire and how to requalify. Is there some other place that I should be looking
