3 M or huntsman ?
Both of them apparently have a great amount of products for all kind of application
I’m sure all of you use adhesives so I would like to know which company you like the products the best in general?
Also 3M DP490 doesn’t exist in the USA what would be the equivalent ?

#2

Both 3M and Huntsman (Araldite) make good products. So it is up to price and availability which make the final choice…

Use the Huntsman Araldite selector app to make a choice from their range.

#3

Worth considering the Plexus adhesive range of products they also make some excellent adhesives/products.

Thank you I will check and also look if it is available in the USA

#5

Plexus ma310 is a very good allround adhesive however it will eat up blue foam which does not happen with 3m dp490, however it is considerably cheeper than dp490.

#6

Thank you for the suggestion About plexus
Can you tell how good is this 3 M dp490 because we don’t have it in the USA
Only one or 2 company sometime have it but they sell it
$ 100 kind of pricey … For 50 ml
We have few DP from 3M here like 420 and 460 but no 490
So I always ask myself why and how good is this 490

#7

I can vouch for DP490 since it is all I use for AL or TI to carbon. I was told by 3M at the time that the only difference is pot life (20, 60 or 90 Min.) 420 and 460 are not available in Germany so I don’t use them.

#8

I will check with 3M if it’s only the pot life time that is ok Because the difference is approx $100 for dp490 and $25 for DP460

#9

By the way do you use it also carbon to carbon (epoxy)?
Thank you

#10

Glueing foam with an MMA is a bit overkill. The glue is way more strong than the foam.

I believe in the USA there is a black variant of Plexus MA310, I would use that for carbon-carbon joints.

I would really need to check on the 3M stuff. 100 USD for 50 ml looks a bit stupid. (buys you at least 2x 400 ml Plexus MA310…)

#11

I agree $100 it’s crazy …I think they bring it from Europe

#12

Plexus ma310 is available in black and white here in the uk. I usually only use the black and buy a crate (12 tubes) at a time of the 400ml tubes.

#13

I checked the price on DP490, which is totally normal at some 20 euro or so (25 dollar). for 50ml units.

For 400 ml units it is some 90 euro. (110 USD)

This is one place where to get the 490dp in the USA
There is another one or 2 places where to get it
But at this price. I don’t think that it’s a deal… :slight_smile:
3M don’t sale 490DP in USA so some people bring it and sale it at any price they want apparently
