Anyone Use This Epoxy?

Ok, sounds reasonable.

I also found this epoxy… very clear, 1 hr pot life, room temp cure, hard, can be oven cured to speed up the cure time. Room temp cure produces a resin that is stable under higher operating temperatures. Don’t ask me how hot you can get it once cured at room temp.

If i can’t get epoxy from the company i’m trying to get from, i’ll probably buy this epoxy resin. How do you think it would do for infusing small parts?

Also what numbers ( viscocity and how it is measured )do you look for in an epoxy for infusing?

Probably not quite as good as a clear poly resin system, which as long as your small parts are purely cosmetic, would be a better choice than epoxy, mean a lot less work, and would be far cheaper.

I’ve used their Ultra Low Viscosity resin (e-Bay #270019321096) in infusions. It works as described . 5 hr pot life and 24 hr to demolding. It’s not perfectly clear (leftover in cup about 1" thick) but not bad. In a flat panel you can’t tell. That’s the resin I used for my sump pump cover.

I think you’ll find a thread on here with the CPS scale of viscosity. I know I seen it somewhere just can’t put my finger on it.

huntsman makes some good infusion epoxies, the 8601 with 8602 hardener has a tg of 140 degrees with cure at room temp, viscosity is about 200cps, 24 hour demold time. if you want epoxy with a higher tg, the huntsman 8604 has a tg of 180 and its viscosity is about 400 cps, also room temp cure, demold after 24 hours. these can be purchased from northern fiberglass

Although the adtech I use is very good (350cps), I would like something with even lower viscosity. I do heat the mold and the resin a bit to lower it even more, and it works well but I think I will give the Huntsman a try seeing as it has a lower viscosity, and that can’t hurt.

hojo, are you using the huntsman? what is the gel time?

I was able to order more epoxy from Jgreer.com. slight mix up when i asked for a price… he quoted me for 6 gallons instead of the 1-1/2 i was looking for. He’s a stand up guy and doesn’t seem to be in business to make a killing off of the products he sells. Also i got 10ounces of yellow epoxy dye from him for $12. he has like 5 or 6 colors of epoxy dye he sells… yellow, red, blue, black, white and maybe one other like green possibly. I wanted it for mold making.

Six gallons of epoxy/w hardener combined, the price was $276 shipped. I don’t have the specs, but i’ll try and get them from him. I do know it’s very clear… as clear as the PolymerProducts Crystal Clear epoxy. Only very slight amber once it was fully cured 2 inches thick in a cup. The #300 epoxy with #21 hardener. has a pot life of one hour at 70F. 1 and 1/2 gallon kit cost me $77 total shipped to me.

go here, you can check all the datasheets on the huntsman infusion resins: http://www.nfgsales.com/products/components_resins/infusion_resins . I recomend either the 8601 with 8602 hardener, or the 8604. the 8603 is not good for cosmetic parts. and the 8605 and higher require post curing.

Any pics HOJO? The link says transparent but doesn’t mention color. Is there a tint thats noticeable when laminated?

the 8601/8604 resin has a blue transparent hue, but is not noticeable in the part at all. has a very nice finish for the carbon. the 8603 was not good for cosmetic parts because the resin is a milky yellow, which makes the carbon look cloudy/yellowish, not pretty.
