Hi viscosity and for laminating dont really go hand in hand. If west is to flexible, are you sure your fabric choice and/or layup schedule isnt the problem?

Fiberglast has a high temp resin with a Tg around 320f that may work for you. You will probably have to post cure it.

Rapptor
The best laminating epoxy I have found is from Tap Plastics. It is there 4 to 1 epoxy and used for years to make glass parts and fuselages for Dick Hanson Models. It is a true laminating epoxy and is a ton harder than West Systems whether making glass parts or just doing laminations or glassing wings
You will really like the stuff

Not unless you have a way of post curing. The medium hardener is what you'll want if you cant post cure

It has a 20 minute pot life, once you get it out of the pot its a much longer working time. Ive been using it for layups that take 2 hours by the time i start to the time it gets put in the vacuum bag and fully sucked down.


you know, some research and google searchs will bring up a LOT of choices on epoxy laminating resins available. Maybe some of your time devoted to seeing what is out there would be time well spent.

Thomas gives good advice. There are many good laminating resins, and all have some different properties. USC635 is my daily go to resin. I use all three hardeners depending on what I am making.
One more thing to keep in mind. With composite structures, fabric orientation is everything.

This newsgroup turned me on to Gorilla Glue a few years ago and I'll never go back to epoxy. You just have to get the original Gorilla Glue, not the GG version of so many other glues.

If you are laminating wood projects, balsa and plywood then a wood glue would give u the working time and rigidity after it has set. I use a Titebond glue although am not sure which. Has a green lable. Cleans up easily just wipe the excess with a damp cloth

Well I will through my 2 pennies in hear I have used all the above materials at some point. but the OP did not state what he is building, and that just might be the deciding factor. also he did not say how he was measuring his material and that could be the problem, so IMHO I think we all need more info.
But that just me and I am NOT an expert by any stretch

Here u are Rapptor. No its not too much work. But your question should be more exact. In the absence of clarity I chimed in maybe I could be of help. That is why you are here no? For help and not to be insulting...

It is Titebond III Ultimate wood glue.

I have used this epoxy system in business and for models for nearly 25 years, it has a very low viscosity and a long pot life, it works well for laminating fiberglass, carbon fiber or laminating balsa sheeting on foam core wings as well. I am posting just a couple of projects using this epoxy system. The Extra 300 is a fiberglass and Nomex honeycomb fuselage with sheeted foam core wings and tail feathers and the red and yellow Cobra is an all carbon fiber and Nomex honeycomb airframe. There are two hardeners available, the 83 and the 84, I generally like to use the 84.
