ARJAY Technologies pourable ceramics

Has anyone heard of Arjay?

I was at fiberglass coatings in St pete the other day picking up some gelcoat and got into a conversation about transom replacement and core materials. The guy mentioned Arjay 611, or pourable ceramics. He said the strength/ rigidity/tensil and compression was far better than wood or other cores plus it will not rot lighter too. Instead of cutting out the glass skin on the transom you take the cap off, drill/grind auger the wood out, so you are left with a hollow transom two fiberglass skins. than mix and pour the ceramic, he said a 23 would take 15 gal, @ a cost of about $160

Has anyone tried this method or heard of it? He also said this can be done with stringers as well.

Hey neighbor.......I used it, as well as my brother. We are both very stisfied. There are some "secrets" we learned. If you want to give it a try PM me. Seeya

Between the datasheet and MSDS it looks like polyester resin and microbaloons. Kind of dense, though. 7.1-7.3 lb isn't much less dense (lighter) than water, and certainly more dense than many woods. And isn't there an issue with polyester in wet locations? Better than wood, but not ideal.

I was looking at research papers on doing this and found a paper showing microbaloons and vinylester as having a much lower density when 50-60% microbaloons. At 60% it starts to run the risk of fracture like a ceramic, but the skins contain it. Generally stronger than douglas fir. I will see if I can find the reference.

I also used ARJAY to pour my transom great product.

So it is an option.
My transom is fine right now, very solid. But I do want to close in and put on a bracket at some point in the future.

where can you get 15 gallons of that stuff for $160?

From memory........and it ain't what it used to be! I think I paid $115 per five gallon bucket, plus the catalyst. I got a good deal because my brother and I bought seven 5 gal pails at one time. Check with Fiberglass Services in Sarasota 941-923-8112
