NEARLY HALF ITS 2 YEAR USEFUL LIFE ALREADY EXPIRED.
According to Henkel’s website, the “5A” in the batch code on the Loctite 569 bottle that was delivered today, 12/3/25, indicates it was manufactured in January of 2025 and it’s “Use By “ date is “1/27”. So, nearly half of its useful life has already expired. Not happy, especially at $52.06 for 1.69 ounces.
