F/G resin compatibility

[Hou-Chap]

All,

I once again am hoping someone could help me out. I am fabricating a rear baitwell station for my boat. I have sourced a plastic cylindrical tank made of polyethylene that is perfect for what I need. I know F/G resin has problems adhering to some plastics, and was wondering if I will be able to use this tank . Will epoxy resin adhere to this tank if I rough up enough "tooth" for it? I do not have the money it would take to give it a try and "experiment", just to find out it won't work. I am hoping somebody here has had experience with this and can give me some good advice. Thanks again guys for all your help!!

Almost nothing will adhere to polyethlene. that's why they use it for glue bottles. Polyester resin will adhere to pvc. Sometimes you can find laundry tubs that will adhere to either epoxy or polyester. I don't know how large a bait tank needs to be but if you start thinking outside the box you might find a container of the size and shape that you need without having to spend next months mortage money.

Ssor,
Thx for the response. That's pretty much what I figured. This tank was the perfect size and cheap. I will have to re-think what I want to do. Maybe I can fab an enclosure and slide that tank inside it?? I hear what your saying on the prices of the manufactured baitwells. I found out pretty quick that if I was going to do this for what I was wanting to spend I was going to have to be creative.

Hey Chap, You didn't say what you had in mind for a bait station, but if you wrap that cylinder shaped tank in coated butcher paper, with the coated surface out, and then glass it into place, as long as you don't trap it at the top you should be able to pull it out and strip the paper off. Then with careful planning you can complete the other work around it. Just measure it carefully to insure that it is not smaller at the top than at the bottom, maybe even fill it with water before you start your glass work.

And then bring the PE tube back to the seller, saying you can't use it after all...

Yeah, why not use the cylinder as a mould, after all, nothing will stick to it.

Wrapping it with coated paper just makes it a little bigger and therefore easier to pull out. Sometimes when I need to make a sleeve with a close fit I wrap waxed paper around the piece to be supported and then glass that. When I remove the core the paper tears and can be pulled free and I have a nice close fit sleeve.

I am leaning towards using the tank for a mould. It is the perfect shape for what I am wanting to do. The plus side is I shouldn't have to force it out, I don't guess I will even have to use any PVA. I like the wax paper idea, I have never thought of doing that before. Could come in handy. I may tackle this over the weekend weather permitting. Thanks for all the feedback!!
