Has anyone on the list used Aeromarine brand epoxies? They are available at http://www.jgreer.com I seek feedback from users. Off topic, since I haven't used that brand: When it comes to low-cost general-purpose epoxies, I prefer the 635 system from US Composites (http://www.uscomposites.com) with 3:1 medium hardener. In the 2.66-gallon kit, it costs about $30 per gallon (about the same as polyester resin at the hardware store), has a nice 3-hour working time for thick layups, and I've had good consistent cure from it. However, I cannot attest to the strength or other properties of these materials. I've been using it only for tooling parts, so I don't consider it of great importance at this time. I'd want to do a coupon tests before I used it for any sort of flight or structural article. Thanks, and best regards to all Bob K. http://www.hpaircraft.com |
