Shelf life dates are normally conservative. Years ago we would "requalify" adhesives by running lapshear tests. Don't know if Loctite has a "requalification" test or not. I do know that we have used Loctite chipbonders that were over a year out of

On a lot of Loctite products there is a shelf life stated via a lot number on the bottle. It has been my experience as a distributor that Loctite will in most instances re-certify a product for an extended period of time, sometimes up to a year based

For CYA reasons you made the right choice (I agree with Mark). But, for whatever it is worth I have used Loctite 383 up to 4 years past it's shelf life It worked fine for my application (wire tacking, FR4 bonding etc...). Have you ever seen a shelf

Hi, I am looking for anyone that uses the Henkel/Loctite FP4460 glob top encapsulant. We use considerably less than the minimum order quantity during the product's 6 month shelf life and could really use a reseller or company that may be intere

Where I worked we used a different chip bonder. When we had trouble with flux entrapment in the epoxy from the wave solder, we checked the date of the epoxy. The tube didn't have one but the manufacturer gave a shelf life of 6 months and then the s

I hope that someone can help me with my problem! I am experiencing a lot of glued on parts falling off in the wave solder machine. A little information about my process: 1)We use Loctite 3609 glue that is used up long before its shelf life 2)Our pa

Is anyone still using Loctite 348 chipbonder for bottom side attachment? Is it truly adequate for dispensing up to 18k/hour? We will be dispensing with a Camelot 2800, so somewhere in the neighborhood of 15k/hr. is as fast as we'll ever see. I'm c

Hi, I've been looking into UV cureable conformal coating and the UV ovens but a chemist I know is very negative about this. He suggest by heating standard conformal coating to 90deg for a couple of minutes will make the product good enough to handle
