Is there a good way to remove labels and sticky residues?

Old identification or QC fault labels can be difficult to remove. They either leave sticky adhesive behind that is insoluble by commonly available solvents like isopropyl alcohol (IPA), or are so dried and baked-on that they won’t budge. While consumer products like Goo Gone or bug-and-tar remover are common to see on workbenches, Chemtronics offers a cleaner that is actually intended for PCB repair called The Mighty Pen®. It contains a fast acting solvent that breaks down dried and sticky adhesives.

How do I figure out the shelf life of a product?

The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.chemtronics.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.chemtronics.com/batch-codes.
