\u00a0Product not in stock anywhere! <\/strong><\/p>\n

You may have asked why some of our adhesives cannot be found in stock at a local distributor location, and that\u2019s a great question!<\/p>\n

The short answer is Quality Control.<\/p>\n

The longer answer follows.<\/p>\n

Permabond manufactures adhesives formulated for engineered designs with strict requirements for performance during and after application. We know our customers rely on the dependability of adhesive performance to ensure that manufacturing and assembly processes run smoothly. We also know that our customers may require technical support before, during and after the selection of an adhesive.<\/p>\n

Distributor Partners of Permabond meet rigid criteria that includes product training to help customers through the selection, testing, approval and specification processes. Every customer has unique needs that are most effectively managed by a team of folks from both Permabond and the local distributor.<\/p>\n

It is by intentional plan that our products are not carried in retail home hardware stores. These channels do not typically offer suitable storage conditions for many products and are often not prepared or committed to monitoring shelf life.\u00a0 This can result in out of date material with poor performance.<\/p>\n

I just want a sample to test.<\/strong><\/p>\n

But, you say, I am not yet in production, I\u2019m still in testing and trials. How can I get a sample of adhesive quickly?<\/p>\n

We appreciate the time sensitive aspects of customer projects and when needed, can work with you to arrange a drop shipment when local stock is not available.<\/p>\n

Permabond is committed to providing solutions for customer sealing and bonding needs and understands that your best results will come with the freshest product. It is our goal to make sure that we sell and ship only quality product that meet customer requirements.<\/p>\n

What happens if the product I test is not fresh adhesive but beyond its shelf life?<\/strong><\/h3>\n

Poor performance may not be the best description of what can happen when out of date adhesive is used.\u00a0 Changes that occur with aging can sometimes be seen as a benefit.<\/p>\n

Jim in Michigan<\/h4>\n

\"old\"New<\/p>\n

Here\u2019s what happened to Jim in Michigan.\u00a0 Jim called Permabond looking for \u201cCA glue number 02.\u201d\u00a0 He had an old bottle and tried it, and it worked great \u2013 he just needed to get some more.\u00a0 The only trouble is he couldn\u2019t find anyone with ca glue 02 in stock.\u00a0 Since we don\u2019t make a cyanoacrylate<\/a> adhesive 02, I expected he wanted Permabond 102.\u00a0 He sent me a picture of the bottle, and yes, that label had been scuffed off to the point of being illegible.<\/p>\n

There was a bit of nostalgia for the near antique logo \/ and label I saw in that photo \u2013 clearly, the cyanoacrylate Jim tested was a minimum of 5 years old.\u00a0 Permabond 102 in a one-ounce package has a shelf life of 1 year \u2013 when stored refrigerated.\u00a0 Jim\u2019s bottle had been lying around for over 5 years in a factory.\u00a0 I was surprised that adhesive that old had worked at all.\u00a0 So with a bit of pride for our quality and purity of our cyanoacrylates \u2013 I sent Jim a fresh sample.\u00a0 However, upon testing, Jim called to announce \u201cthis new ca glue doesn\u2019t work.\u201d\u00a0 We discovered that Jim was attaching molding onto curved parts and the fresh ca glue was curing before he could align the parts properly.\u00a0 We were able to provide a delayed set cyanoacrylate that met his needs.<\/p>\n

Heather in California<\/h4>\n

Heather in California had a similar problem.\u00a0 She was looking for a single part epoxy<\/a> to pot an area in a prototype and found a cartridge of Permabond ES558 on a shelf in her design lab.\u00a0 The single component epoxy filled the area neatly without flowing excessively.\u00a0 The cartridge of Permabond ES558 had a one-year shelf life when stored refrigerated.<\/p>\n

The epoxy Heather used was NOT fresh adhesive. It was 2 years old and unrefrigerated.\u00a0 When additional prototypes needed to be made, fresh epoxy ES558 was used.\u00a0 Heather called and said \u2013 \u201cI must have ordered the wrong product.\u00a0 Before I had an epoxy putty, but what I received is too thin.\u00a0 It flows out of the area during the heat cure.\u00a0 How do I order the epoxy putty?\u201d\u00a0 Permabond ES558 is designed to be free flowing \u2013 so a few questions later we determined the trouble and provided Heather with a non-sag epoxy adhesive.<\/p>\n

I\u2019ve heard from many engineers that they do very preliminary testing with old adhesive that is lying around and if that works, the assumption is the fresh adhesive will work better.\u00a0 Again, poor performance is not the best description \u2013 perhaps inconsistent performance is a better phrase.<\/p>\n

More examples<\/h5>\n

Let\u2019s look at a few other examples of adhesive aging that might appear as benefits to some include:<\/p>\n
