Thanks for the replies guys. A bit more detail about the process if it helps: This process is about pre-treating glass bottles prior to printing with organic UV cured inks. As I understand it, the aminosilane is indeed forming a chemical layer on the inorganic glass for the organic compounds in the ink to bond with. before being sprayed with the aminosilane solution, the bottles are flamed with gas burners to remove the cold end coating (a kind of protective wax on glass to stop it scratching in transit) and increase the surface energy to help the ink properly 'wet' onto the glass. I've included the SDS for the S1 Series of inks we use, along with the sheets for Part A and Part B.

Hi - Looking for some help identifying a chemical compound that I use in one of my manufacturing processes. The compound in question is supplied by the OEM of my equipment and is part of an adhesion promotor for printing directly onto glass. It's one of three parts in the end solution that's used. I tried looking at the Safety Data Sheet to see what it is but there isn't any CAS number or description as it lists the substance as non-harmful. I'm trying to source alternative supplies, but not being able to identify this compound is making that difficult. The three parts in the end solution are Distilled Water (92%) Part A - liquid (2%) - this is the one I can't identify Part B - liquid (6%) - 3-Aminopropyltriethoxysilane CAS 919-30-2 The process for creating the solution involves mixing the distilled water and Part A for 30mins, then adding Part B and mixing for a further 30mins. I'm guessing the part A does something to the water to make the 3-Aminopropyltriethoxysilane soluble or not break down perhaps, but I really don't know. I'm hoping someone might know based on the 3-Aminopropyltriethoxysilane what function Part A could be doing, and therefore what kind of compound it might be, or alternatively, know of any UK based facilities that could test a sample and let me know. Any help would be much appreciated! Thanks Ben
