Black water tank material

[mamos]

Hi All

Things are progressing with the re building of out 1972 Globe Trotter.

We have to do some work to the black water tank.

It is made of plastic and we need a glue that will stick to it.

The plastic is quite soft like Tupperware and is a greeny blue colour.

Any idea what the actual material is so i can find a glue.

The glue need to stick to the plastic and fibreglass

Any help would be really appreciated

Thanks

I have constructed a new tank out of fibre glass and I want to bond the tank fittings into the new tank

I have tried sikaflex but even this does not stick to it

The black water tanks are made of polyethylene. No glue sticks to it. You should use fittings made of the same material and weld them into place.

West System Epoxy makes an epoxy glue called G Flex. Folks use it to attach hatch covers to kayaks and other plastics. The sheet says it will work on poly. Might be worth a try. I have use it on several plastic items with good success.

Check out West Systems G-Flex epoxy. They have a video where they cut a plastic kayak in half and then "glue" it back together. I've used West 105 epoxy for years building small boats and canoes. The G-flex is new formulated for roto-molded plastics. I've used it for small projects. I picked up a guart last week from West Marine (a different company that sells West Systems), it's expensive. I hope to fix some cracks in shower pan and other ABS parts in the next few weeks.
