« on: May 17, 2008, 07:08:31 pm »
I`m looking to stick my varistream box on the side of the tank frame and won`t something that`s going to hold it,in the past i`ve used cable ties as it keeped coming off.I was going to try a good spread of superglue down each corner,does anyone recommend another glue or product.

The snag with trying to stick plastic is that the only effective adhesives are the ones that "melt" the plastic a bit - solvent adhesives, but they don't work on metal.

Evo-Stik Contact Adhesive will probably do it

When you buy superglue or similar, they give you a plastic spatula to stir it - because the glue doesn't stick to plastic!!!

Araldyte, its an epoxy resin.....it super super strong and the reason it doesnt stick to the caps is because the ingredients are in 2 tubes!!!!!!! This stuff will bond ANYTHING

Epoxy adhesives are a major part of the class of adhesives called "structural adhesives" or "engineering adhesives" (which also includes polyurethane, acrylic, cyanoacrylate, and other chemistries.) These high performance adhesives are used in the construction of aircraft, automobiles, bicycles, boats, golf clubs, skis, snow boards, and other applications where high strength bonds are required. Epoxy adhesives can be developed to suit almost any application. They are exceptional adhesives for wood, metal, glass, stone, and some plastics. They can be made flexible or rigid, transparent or opaque/colored, fast setting or extremely slow setting. Epoxy adhesives are almost unmatched in heat and chemical resistance among common adhesives. In general, epoxy adhesives cured with heat will be more heat- and chemical-resistant than those cured at room temperature.

Your tank is made of Polypropylene the same material as the caps of super glue, its about the only plastic that super glue won't stick.

Glue will one of two things. It will either stick it permanently, or not at all. Neither of those is really desirable. What you want is a semi-permanent attachment - that's why these things are held in place by screw fasteners.

Could you glue velcro strips to both the controller and the tank. That way, you get the best of both worlds - semi permanent.

I`ve done that before and they don`t hold it,heavy duty ones aswell.Self tappers are a good idea the one i have at the moment has them but i`m fitting my old varistream and don`t want to drill.Will that araldite that Luke said do the trick.

The problem with glue is that it's either permanent or unpredictably temporary.

What you need from an engineering point of view is semi-permanent fixture. By that I mean that you can fix it permanently if you so wish, and have the option of removing it any time you wish.

Could you screw the controller to a wooden board and somehow attach the board to the frame? That would be semi-permanent.

why not use cable ties, they would hold it on no damage to frame, drill few small holes in back of control thread and tighten.

That`s a good idea Ian,you mean screw the box to the strips of metal and then bend them over the frame don`t you.That could work mate.

Out of interest have you seperated it from the pump? How far is it from the pump? Where is the pump in all this?
