Loctite 480 Vs. 410 Vs. 380

[Greenie]

Please forget about the high failure rate of these......

 

I am wondering if anyone knows the practical/function difference between these products. I have used Loctite 480 for certain applications on BHR with reasonable success. Nothing is perfect.

 

I looked here to get more detailed answers, but I am still not certain. 380, 410, and 480 are all listed under CA adhesives, "toughened", black.

380 says tight fitting, viscosity 300

410 says gap filling, viscosity 3500

480 says tight fitting, viscosity 200

 

Otherwise, they look quite similar.

 

Has anyone used 410 or 380? I found an old thread where Ron Zorn stated "black max" was the same as 480, and searching for that product, I seem to get listings for loctite 380, with an occasional listing for 480.

Off the top of my head, after a day of preparing to go to a pen show, no.

 

You will find application notes for each product on the Loctite website. Lots of useful information there and a good place to start. Loctite has also been very helpful when I've called them with specific questions after reading the tech data.

I sorted this out once. I look and see if I can find what I determined.

Thanks guys! Otherwise I will stick to the 480.

OK I found it.

 

Loctite 380 is ethyl 2-cyanoacrylate, carbon black and hydroquinone.

Loctite 410 is the same as 380 with a filler added. (We were unable to determine exactly what the filler is.)

Loctite 480 is the same as 380 with phthalic anhydride added.

Great info FarmBoy!

 

I found this with superficial investigation into CA with pthalic anhydride, and to whatever extent I can trust Wikipedia.....

https://en.wikipedia.org/wiki/Cyanoacrylate , see most of the way down page under "Aquaria"

 

"However, as a class of adhesives, traditional cyanoacrylates are classified as having "weak" resistance to both moisture and heat^[5] although the inclusion of phthalic anhydride reportedly counteracts both of these characteristics.^[6] "

Based on this minimal information, it looks like Loctite 480 would be preferred for pens, although the additive makes it better for usage under water in an aquarium, so it might be overkill to use 480 over 380 on a pen.

I don't know..... Moisture from ink, moisture from sweat, heat in southern California... I like to go with heavy duty that's less likely to fail.
