WebAcetals are the protecting groups for aldehydes and ketones.They can be used, for example, when a selective reduction of an ester is needed in the presence of an aldehyde or a ketone:. Remember, aldehydes are more reactive than esters and when mixed with, for example LiAlH 4, they will react first before the ester is reduced and that is when the … WebPresence of primer may be detected by means of a UV inspection lamp (365 nm). If polyolefin and more active or easier to bond materials are involved, apply the primer to the polyolefin only. For best results, apply LOCTITE® cyanoacrylate adhesive and bond assembly right after the LOCTITE® SF 770 dries on the surface of the substrate.
