EPOXY - resin:hardener ratios ?
Visit: http://69.239.32.181/Jeffco/Hardener...ustomers2_html
and you'll see that each hardener is formulated for a specific use and nominal cure time. You'll also notice the chemistry of hardeners is not uniform, noting for example the various "main ingredients" that comprise these many selections: Amidoamine Aliphatic mannich Modified polyamine Modified aliphatic amine Novel modified cycloaliphatic Modified polyamide/polyamine etc... 'What's going on' is apparently an extensive ammount of research to find a combination of chemistry that perform specific tasks. BTW, I've used the Jeffco products (almost) exclusively in hand laminating my project (their 1310-L6 / 3138) in either 50 or 5 gallon increments and am happy with the performance / price. Yes, I do live in a BIG city, but they do sell direct to "non-annoying'' novices. (By this I mean they are *not* West or System 3 with a big "customer care" department willing to guide the uninitiated through the process). MW Los Angeles |
