Glue for reef tank

[Richie49]

I bought this glue and was wondering if it is safe to use in my reef tank?please let me know thank

 

[jsker]

Looks like that will work

 

[Richie49]

But it has ethyl cyanoacetate, is that safe?

 

[Richie49]

It also has cyanoacrylate

Pretty sure @Randy Holmes-Farley knows this.

Ethyl cyanoacetate is not safe for people so I assume that it is not safe for your fish/coral. It is on the EPA list of Hazardous materials.

However, it really depends on the concentration on whether is it safe or not. But then, better be safe than sorry, pun intended.

Dang it, I spent $5 on it lol

Many people use these types of glues in reef tanks for frags and such, although I generally would not try to use it underwater because it may not work that way.

 

[Richie49]

So you're saying that I should try this one?

 

[Richie49]

But it has 2 different ingredients

ethyl cyanoacrylate is just fine to use....and actually needs moisture (water) to cure properly. It is the "common" cyanacrylate in Krazy Glue, Super Glue and many other "one drop" glues. I see no problem in using it. If it makes you feel more comfortable, it's an acrylic resin....similar to Plexiglass.

 

[Richie49]

But the one you are saying is ethyl cyanoacrylate. I got one that has cyanoacrylate and ethyl cyanoacetate

I think you may be misunderstanding the chemistry. "Cyanoacrylate" is not a chemical, at least not one in adhesives.

The two ingredients in your product are ethylcyanoacrylate and an inhibitor to keep it from hardening in the tube. People often refer to this type of adhesive as a cyanoacrylate, and sometimes they may contain other varieties of monomer, such as methylcyanoacrylate.

Here's the data sheet for your glue:

http://www.krazyglue.com/docs/default-source/MSDS-Sheets/skg0483.pdf?sfvrsn=4

from it:

Section 3 - COMPOSITION / INFORMATION ON INGREDIENTS
Component Name..................................................................Percent
Ethyl cyanoacrylate................................................................. >95.0
2,2'-Methylenebis(4-methyl-6-tert-butylphenol)..................... 0.1%

 

[Richie49]

But what is the cyanoACETATE?

 

[Richie49]

Nevermind, I got this new glue instead, it ONLY has cyanoacrylate. Will this one work?

 

[Randy Holmes-Farley Verified Community Expert]

Again, you are misunderstanding the chemical names.

There is no cyanoacetate in an adhesive. There is no individual chemical called cyanoacrylate that is in an adhesive. "Cyanoacrylate" is a laymans term for a family of chemicals, of which ethyl cyanoacetate is the one in the glues.

 

[Richie49]

But this new one I got says that it is not recommended for bonding parts which are subject to great shock or immersion in water. So will this one work?
