pearlyred Posted May 9, 2005 Report Share Posted May 9, 2005 Hi, just wondering what types of glue are recommended for repairs on a perspex fish tank. Its only about 50 ltrs but its useful to have around. Silicone wont do the job will it? cheers Quote Link to comment Share on other sites More sharing options...
Warren Posted May 9, 2005 Report Share Posted May 9, 2005 Silicone won't repair structural problems and won't strick very well to the plastic unless you sand it and use the correct primer. You need a glue called Acrifix. It's pretty good stuff but not cheap (about $25 for a 50ml tube). I don't know anyone in your area with it. Look for someone who specialises and/or imports bulk raw plastic materials. There is a local plastics industry here. The owner keeps fish so it's a bonus for me when I go there to get stuff as he's interested in what I'm doing. Gives a really good price too!!

Jo1 Posted May 9, 2005 Report Share Posted May 9, 2005 The Primer, if you use silicone, is Fosroc Primer No 9. Apply, leave 10 mins and then apply silicone. Quote Link to comment Share on other sites More sharing options...

Hah, no idea actually, whats the difference? Its just a wee plastic type tank. Prolly not worth spending TOO much on, but if i can get a cheap fix its worth it. ta.

Warren Posted May 10, 2005 Report Share Posted May 10, 2005 If it was polycarb you could bend the from face until it was touching the back face. If it is acrylic (perspex) it will crack before it bends very far. Polycarb is also known as lexan and it's extremely flexible and tough. It's pretty unlikely to be polycarb. It may not be perspex (acrylic) either but some other polymer that's quite similar. Take the tank to a plastics specialist. They may be able to ID the plastic. It's pretty important to get the correct glues for plastics. Quote Link to comment Share on other sites More sharing options...
