Is ABS sheet reef safe?

As the title says. Thinking of using black ABS sheet for an overflow box.

Perfect! Thanks Chin. Do you know if it bonds to acrylic?

[Chin_Lee]

I believe so - use weldon16. that stuff seems to bond everything together. but i don't believe its a very strong bond.... you might want to check into that or if somebody else can pipe in.....

Actually strenght isn't all that important for this application. Thanks for the help.

Weldon 16 is a thicker, more syrupy version of Weld-on 4. I dont know if they surfaces they will bond are different or not however?

16 Will act as a 'gap filler' as well, but the portions where it is not a direct bond between the 2 surfaces and the 16 is just filling will not be nearly as strong(infact you can break it off with a fingernail).

Weld-on 4, when applied correctly, is amazingly strong! I have heard it should work for ABS as well.

If you can find a page with the different uses of each Weld-on, you should be able to find one for the job you need.

This site does not seem to indicate #16 will work with things other than acrylic however:

Here we go... didnt really read through it much but this page might help:

I used 16 to build my overflow box out of ABS and it seems to be a strong bond(recomended by industrial plastics).I'll check out those links for more info...
Thanks, Chris.
