Re: Resin Types In Catamaran Construction

Generally, a plug, which is the male pattern that you make a female mold from, is not built from expensive materials because you are just going to dispose of it when you have pulled the mold. It just...

Re: Resin Types In Catamaran Construction

Very interesting Phil,
I have never tried laminating over polyester gelcoat with epoxy or had any desire to do so. As you know gelcoat is insanely heavy due to the required mil thickness so has no...

Re: Resin Types In Catamaran Construction

I suspect that you are familiar with the West epoxy resins we use at work which are in fact substantially weaker in tensile strength than the VE we infuse with as are all of the readily available...

Re: Resin Types In Catamaran Construction

All good points Phil. However my point is that most people when they think of epoxy, they are thinking, as you are, of the 2 part epoxies such as West systems 105/205/206. Why, because they have been...
