Default Does 5200 adhere/bond to starboard???

I need to remount a fuel filter that tore out. Do not want to re-screw. Looking to mount filter to piece of starboard which in turn is bonded to fiberglass.

Does quick set 5200 bond to starboard??? If not what does? Anyone tried this successfully?

Thanks!

Yes, 5200 bonds to starboard.

Flame treat the starboard first with a MAPP or propane torch

I just used 4200 to make a starboard bracket for my vhf mic and i cant pull the thing apart so I must assume 5200 will ??

All day everyday - Do Amp back boards all the time. Rough up both surfaces and clean with Acetone.

Instead of acetone use Zylene, it will soften it up.

A scuffing, cleaning wit Acetone or Zylene and 5200 will do the trick.

According to the company, nothing properly adheres to Starboard. If you want to glue a piece of Starboard to something else, the best general approach is to create a rough surface that gives the bonding agent something to grip. Ideally something that creates pockets or a way for the bonding agent to get fully trapped in some way.
That being said, many people, including myself, have managed to glue Starboard using various high strength adhesives with decent results, but I have only done it for things where I do not need to really trust the bond.

This stuff is good for LDPE/HDPE, not sure how well it bonds to fiberglass though, maybe someone else will know:

For something with fittings and hose connections that carries fuel, I’d err on the side of caution and re-screw. Or better yet, thru bolt. I wouldn’t want any chance of that falling off and bouncing around.

5200 is difficult to use with starboard. While it may stick to starboard if correctly prepared, I would not use it in this situation, especially dealing whit fuel lines.. Rescrew or throughbolt if able as mentioned above. I think, at a minimum and not recommended, would be to epoxy the starboard in place.

3M's Scotch-Weld DP-8005 or Lord Corporation's 7540-AB

https://www.kingplastic.com/wp-conte...Techniques.pdf

Page 6 of the Info guide (link above) describes the gluing process....

Excerpt from the King Plastic web site :
It is preferable to mechanically fasten or weld King StarBoard®, but when an adhesive is necessary you can use a product called Lord 7542-AB, or 3M's Scotch-Weld DP-8005, or Chem-Set™ 6105 Polyolefin Bonder. We do not represent these products, make any claims about their abilities or accept liability for them.Jun 22, 2011.

I have personally used the Chem-Set 6105 product, and it does work without any scuffing or heat treating... I ain't cheap !

Good luck

This is not correct. 5200 is an adhesive sealant, specifically designed to bond surfaces together. Check your facts.

I've used this product for fastening materials beneath clean room floors where drilling anchors into the concrete is a no no. Thought about trying it in the bilge. Super strong bonding, and waterproof. Can't vouch for bonding starboard to other materials though.

From 3M, specifically about this situation where someone tried to do this- Starboard is made from a High-Density Polyethylene Plastic which can be extremely difficult to bond and 5200 is not the right choice for this type of substrate.
So yes, it is sticky and adheres to things, but it is not what this situation calls for. I would not use 5200 for this situation with starboard, especially for something as significant as fuel lines.

Marine Tex makes a product called Flex Set which works with Starboard when properly treated, and the flame treatment is pretty easy.


The best way, by far, is going to be to either (a) use expanded PVC which is cheaper than Starboard, available at Home Depot and Lowes, and easy to glue, or (b) to use a router and cut grooves in the back of the starboard that can be filled with the 5200 to create a full mechanical bond.

I have used 5200 on Starboard and had it peel like it was Scotch tape. Other people have had it work... so I believe it can be done, I just would not want to trust adhesion alone with Starboard.


As to the other comment, 5200 is absolutely an adhesive. Normally, it is a spectacular adhesive, but just not on this particular material.
