Your epoxy and plastic
How well does your epoxy adhere to plastic?
It seems that I have a teeny tiny fissure/scratch where the volute of my skimmer pump meets the pump body that is preventing a seal. I need a filler more than a glue as the fissure doesn't go all the way through to the exterior of the pump. So I was considering whether using a bit of epoxy to fill the fissure would be the best method of repair. It's the regular hard black plastic of a Sedra pump. Thanks. |

Epoxy does not like smooth services so make sure you rough it up a bit.
There is so many epoxies these days not sure what you have, but most epoxies have pretty good bond strength. Or you could try to melt it back together with a solder iron that might work.

IME epoxy doesn't adhere all that well to plastic, although if you add a little sawdust or fine plastic filings to the epoxy when you mix it, it might hold better. Esp. since you seem to be looking for more of a 'filler'. Failing that, you might try something like weldon or another solvent type of adhesive. If it's black plastic, a little ABS solvent cement might do the trick.

I have weldon 16, works great on acrylic but wont stick to most plastics. I have some stuff called rez-n-bond, thin like water and works great on most plastics but has no filler capabilities unless you dissolve some plastic shavings in it and use it as a filler that way.

Check lordco or maybe other auto parts place for fusor products. We use fusor products for all our plastic repairs at work(bodyshop). Its like 50+ bucks per tube but it is very strong and it will seal anything you need. I used fusor 142 on my reeflo pump to stop a leak and so far so good.

While it may work I would not recommend it for plastic. Best to find an adhesive specifically for material of your skimmer.
Epoxy has a few applications IME and include attaching corals, leveling low spots in live rock to better facilitate aquascaping, making bases for acans, zoas and other encrusting corals, among others.
