What adhesive or solvent is used to laminate two pieces of [KING StarBoard or Whale Board] together to form a structural bond?
Phil T posted 04-09-2010 11:52 AM ET (US)
For KING StarBoard I have read you can use a product called #7540-AB or 3M's Scotch-Weld DP-8005.

Screws.

I did some research on this site last year and learned that King StarBoard and Whale Board are not the same thing. They are made from different materials. One of the key differences is that epoxy will stick to Whale Board, but it will not stick to King StarBoard.

I have had very good results bonding KING StarBoard with 3M's Scotch Guard DP 8005 two-part epoxy. What are you trying to accomplish?

Marine Tex has a new product called "flex set" available at West Marine they claim works on KING StarBoard. Not an endorsement but it worked well on a poly pool filter.

I am planning to make a small footprint bracket for holding the 54-quart cooler seat in front of my console. In the Dauntless 14, there is precious little flat floor area between the original Whaler designed bracket and the vertical surface of the hull. To make matters worse, the brackets position the cooler about three inches ahead of the center console. By moving the cooler toward the console and reducing the footprint of the brackets I can gain five inches of floor space and eliminate the toe stubber. I plan to use two of the three existing screw holes for the new bracket and just put a screw in the hole that will be exposed so I don't have to deal with non-skid repair.
I have designed a bracket that can be fabricated with stainless. I was considering an alternative approach with the starboard because I have a wood shop and could form the starboard myself. Now I think I will just bite the bullet and bring my stainless design to life. I'll need to find a local metal bender that can get it done before walleye season opens. Any other ideas are welcome.

K Albus: is correct I have not, do not know of anything that will stick to KING StarBoard, Whale Board can be bonded with an epoxy. The only way that I know to put two peices of starboard together is with (aircraft) nuts and bolts. I do not even think the threads of a screw in KING StarBoard will hold up.

My experience with KING Starboard has been that it does indeed take screw threads very well if the proper drill is used before threading.

King sells a welding solvent for their material. I have used it, and it does very well. Before you put the solvent down, you have to take a blowtorch to the area being "Welded" -- the heat takes off a glaze that will allow the solvent to work.
You Starboard Distributor should have this solvent and the applicator gun (it mixes in two parts like epoxy) for sale.

There are five situations required for the bonding as proposed in the initial question:
--KING Starboard to KING Starboard
--Whaler Board to Whaler Board
--KING Starboard to Whaler Board, and vice versa
--KING Starboard to something other than KING Starboard or Whaler Board
--Whaler Board to something other than Whaler Board or KING Starboard
If you recommend a bonding agent, please be clear about which application it will be used in.

Well, the thread has been modified since I originally read and responded to it. Since the original post (as I recall) said to laminate two pieces King Board, I assumed that both pieces were the Starboard.
Subsequent posters introduced the ambiguity of Starboard or Whaler Board.
So my answer, more clearly stated, is that King products sells a King solvent weld adhesive for King Starboard. It (Starboard) still has to be heated with a blowtorch, and it will bond very well if this weld adhesive is mixed and used as directed.
I have no experience with Whale Board.
Sorry.

The need is for King Starboard to King Starboard. I purchased some material today and also sent out a request for proposal to a couple of metal shops for the stainless version. I have a design for both so it depends on price. I may just knock out a couple of the King Starboard versions to gain some experience with the material.

OK.
I'm talking about adhering King Starboard to King Starboard.
In the following continuouswave link, under "macfam", I posted several pictures of King Starboard storage boxes mounted in my former 25 Revenge WT.
The King Starboard was heated and bent into shape, and the spline seam holding the boxes together used 3M DP 8005 epoxy.
This bond was exceptionally strong.
The boxes were fastened to the floor with screws into mahogany cleats to further bolster the strength, however prior to that, those seams were solid! You could not get them apart.
Believe me, these boxes took plenty of stress and abuse, and the epoxied seams never loosened.
Conclusion: Properly prepared, and applied, King Starboard can successfully be adhered to King Starboard using 3M DP 8005 2-part epoxy.

The scope of the discussion included both KING StarBoard and Whale Board from the very beginning. There was no modification of the scope of the discussion. The initial TOPIC mentioned both KING StarBoard and Whale Board as materials to be bonded.
Thanks to respondents who clarified the application their adhesive or bonding technique was intended for.
When KING Starboard is bonded to KING Starboard using the KING welding technique and adhesive, is there a specified strength of the bond expressed as a percentage of the original material strength?
