Osmosis with epoxy.

Sometimes disagreements start off on the wrong foot, but if we could get to specific details -- what exact resin, solvent percentage, marine ply or other wood, and how were properties tested -- a more useful discussion could develop.

He knows what is talking about.

Could you please explain how you arrived at this conclusion.

Someone wrote with his negative:

You start the attacks on people then beg for mommy to come save you

Interesting tone. Show the quality of this particular thread.
The moderator is not my mommy, is the moderator. Perhaps if you don't know what a moderator is, I suggest you get out of the forum.
One thing everyone has to understand, I tell the truth, and all the anonymous negative will not change my course of action.
I AM THE ONLY ONE HERE WHO USE PAUL PRODUCT.
So all of you please refrain to be stupid and ignorant with your so-call proficiency in chemistry (which by the you don't have)
So to all my red dot friend, get real, and start working inset of gossiping. Use your finger to write a check to Paul for buying its product, and then come back.
If you are no too stingy.

Perhaps.. but it never was about Pauls products and I'm sure they are top quality.. The question was about using solvent with epoxy, so tell us if you do that..

No...you aren't. I have used probably 10 times as much as you have. I have used it unadulterated and as such it works quite well. The question for me then becomes why should this....of all the epoxies on the market that specifically recommend not thinning...be thinable by the consumer. I too would like to see actual numbers and not anecdotal information.

As to your tone...perhaps you are the one should consider leaving the forum. If you can't carry on a discussion like a civilized, educated adult then most people here won't be interested in anything you have to say anyways.

Thanks LB - couldn't have said it better.

And, to add, its not the person who has used a single particular product who is the authority on it - its the person who has used MANY different products, and has rigorously compared and tested them all, who has the most credence.

But I digress - this is about the science of 'thinning' - and as LB says - lets see actual figures and discussion on it being a good idea, as opposed to all the figures that say its often not a good idea.

The reports I have read ( and included earlier ) indicate that with most epoxies
1) It doesn't improve adhesion
2) It creates a water permeable layer
3) It creates a mechanically inferior bond.

Lister, you made a blanket statement that Pauls epoxy is "the best that you can buy" then you stated in another post that you have used just 8 gallons of it? now im not disputing that it is good epoxy, im sure it is but the best that you can buy? that needs to be explained. What other epoxies have you tested it against, how did you conduct your tests? How much epoxy have you used in your lifetime? ive used thousands of gallons over more than 35yrs from many different manufacturers and i couldnt say that any one brand is "the best you can buy" some work better than others for different purposes.
BTW,thank you for the compliment.

OK you are a genuine genius realy, you used far more epoxy than me on my all life and you surely know more about it than me! And I mean it.
My test are not conducted scientifically, just by using it.
The 8 gallons I mentioned was the gallons I bought from him. not the total of gallons from the West, Three and other Systems.
I used the Ciba brand in the 1960 from Switzerland, then using it latter on building the tortured plywood Tornado, and also building with the same system International Moth.
That was the recreational part of my job, normally using tons of coal tar epoxy on the barges.
Also using epoxy for cheap and fast repair. It came on unmarked pails but the best one always came with a 1 to 1 mixture or one to 2 mixture. I find the one to 5 or 4, not flexible enough, and not temperature forgiven.
I slaped the darn thing, I don't studied it. I just follow if it fail or not.
The Paul one never failed, the West had is own share of problems.
Perhaps its me.
I just use it, I don't study it. Doesn't worth it.

Lister, Actually using and observing over a long period of time in the real world is plenty good enough. Most of us need a good all around epoxy and most (but not all) i have used are more than adequate and it comes down to ease of use more than anything and, like you i dont like brittle epoxies,there has never been a time in my career when ive said to myself, gee,i wish i had a more brittle epoxy. I too used a fair bit of Ciba Giegy Araldite and lots of Epiglass back in the 70s and thousand of gallons of Ciba,Jeffco and Hardman press molding epoxies in my snowboard manufacturing days in the 90s in the US and Taiwan and we did a lot of lab testing in those days as they are a lot more demanding to build and have stay together than boats. These days i like to try the different epoxies on the market and will be sure to try Pauls at some point.
