Model Forum / Radio Controlled / Water Models / September 2003Adhesive query
I find that translucent 35mm film boxes (the slightly greasy feeling plastic type used by Fujii etc) make ideal watertight on/off switch containers which can be fitted flush to deck on model yachts but I can't find a reliable adhesive to glue them into the deck and as they are awash at severe angles of heel a waterproof seal is important. Any ideas please? Hi, don't wanna shock you, but I think this material cannot be glued. If you melt the material does it smell like candle-wax? If so, forget the glue, try to melt it to the underground. If not; guaranteed you can glue it with 2-comp glue. Best to use resin/powder products like Pattex' Stabilit express.

Have you tried abrading the surface with sandpaper then rubbing silicone sealant round the tube before using more such sealant to glue the case to the deck?

Look on the bottom for a recycle symbol. On my Fuji box it says HDPE - High Density Polyethylene. It's unlikely you'll find any glue that will stick to that. (Ruling out the kind of acid etching they do to make teflon gluable - not sure HDPE can even be processed that way, though.) The recommended method is heat welding, but, obviously that only works with another heat-weldable material. You could get a watertight seal with an O-ring and/or a somewhat flexible sealant. That would leave the problem of securing it mechanically so you can take the lid off. (Small screws inserted from the inside into the surrounding wood, maybe.) -Wm In another hobby group I read, a fellow was looking for a way to "glue" Delrin to metal. Folks recommended a pricey epoxy.

Here is a report on another group on the use of a product from Home Depot to "glue" film containers together.
