Title: epoxy resin, 1:1 ratio?
Post by: elite51203 on March 25, 2014, 11:17:52 PM
Has anyone heard of an epoxy resin that is a 1:1 ratio?  I have an opportunity to buy an epoxy resin from a local supplier.   They have a 2 gallon kit for ~$70.  Im wondering if it makes 2 gallons of finished product or just 1.  I have asked (email), so I am waiting on a response from them...

The only 1:1 epoxy I've seen/used is the 5 minute type epoxy.  I buy it at HD for about $15 for about a pint total (maybe it's less volume).

If it's truely a 1 to 1 ratio, 2 gallon kit you would get a gallon of resin and a gallon of hardener and would in theory have 2 gallons of mixed resin...like Rick I haven't seen a 1 to 1 mix epoxy sold in bulk, my epoxy come from us composites and is 3 to 1 mix, so a 2 1/2 gallon order would be 2 gallons resin and 2/3 gallon hardener. :thumright:

Some manufacturers dispense in a single pump to single pump ratio. The pumps are calibrated per the resin/hardener, you just dispense a single stroke of each to achieve the correct ratio.

Here's the MAS product:

I get the 1:1 all the time from a local supplier for about the same price, yes a 2 gallon kit will come with 1 gal of resin and 1 gal of hardener.  It's just a little thicker than 1:2, works great for fillets, or anytime you need to thicken resin, you can laminate with it if you have to-  may not give you the best/strongest layup for critical parts but for sealing wood it works great.  Have thinned it too with good results.

I was planning on using it for my transom rebuild and stringers which are obviously structural. So I'm not sure now, since it might be thicker.  My next choice would be US Composites.

This is the product.  Thoughts??



Epoxy Laminating Resin in 2-gallon kits. The more you purchase the lower the price!

1:1 Mix resin is a very high quality for a great price.

Customers say they use this 1:1 instead of a more expensive 2:1 or 3:1 resins.

(We now only carry the more popular 1:1 mix).

This adheres well to gelcoat.

Use with fiberglass, or as a glue, or a finish.

Customers have raved about Superez Laminating Epoxy.

Buy 1 of the 2-gallon kits for $71.95, or purchase 2 of the 2-gallon kits for $67.95 per kit, buy 4 of the 2-gallon kits for $64.95 per kit.

well if it is a laminating epoxy it should be OK.  Check into if it has amine blush when it cures.

I've laminated with the 1:1 and it worked fine, but it does take some convincing to get the glass saturated vs. a thinner resin.  With the thicker it's also easy to use more resin than you need and end up with layers of glass 'floating' within the resin, not as strong as a tight layup - in the real world I doubt that'll cause a failure, but don't quote me on that I'm still just a backyard hack.  Should be able to find the 1:2 for not much more $$$.
Not sure where you're located but Glue Products in West Palm Beach has some nice prices & good help.

THIS^      Even though it says laminating it still might be a pain. See how thick it is compared to others.   Really gotta be warm out for most 1:1s to penetrate well...

OK to use to mix glue, but I would not use it for wetting out glass.  So that means you would buy two different epoxies?  Just get one epoxy that can do both jobs
