The major resin manufacturers such as Dow and Shell and Ciba [now called something else...hard to keep track of the new name for some of these companies] offer a variety of modified resins as well as the basic unmodified ones. Those same companies also offer a variety of raw materials used as curing agents, as well as their own mixes of curing agents premixed for some combination of properties they suppose are wanted by some target market groups.

Anyone can start an "epoxy business" by buying a couple drums of stuff, repackaging it and distributing it. I will admit that calling oneself a distributor sounds a bit better and different than a company or such, as being a distributor implies a large infrastructure exists. I don't believe any real industrial distributor has the time and personnel to sell things over E-bay. I think that guy is repackaging material himself.

The raw materials cost about $12/gallon for these product formulations, and there is adequate margin for low-overhead cottage industries to start up selling preformulated mixes.

There is a large area of the market that does not need sophisticated properties, and can be easily satisfied with these formulations. Many are perfectly adequate, for example, for gluing together fir plywood that will not get much wet, some that may, fiberglass layup and a variety of amateur construction projects. Home Depot, for example, sells a "tabletop epoxy" for about $40/gal.

So, depending on what you are doing, they may or may not be adequate. It is highly unlikely that anyone in that business who promotes their products as "from the same place the name brands do" will have any technical expertise, so if your product doesn't wet your glass sometimes or does something else weird, you are likely on your own. The name brand companies know that adding .02% of so-and-so eliminates a particular kind of problem, and also do their own formulating and use different ingredients, some of which add a lot to the formulation cost. There are reasons for this. Cost comes by adding things that cost more, and lower cost by adding things that cost less. See

You're right on Mr. Bob but i'd sure like to see "the Chemist" get back on this forum

[Paulyboy]

Alright. After reading this and following Bob's link to a 4 year old thread involving ethylene glycol, I have to go on a tangent here. Chemist, if you're still browsing, back me up or shoot me down. I've been told by several people that treating nail fungus with good ole auto parts store ethylene glycol (antifreeze) is quick, effective and cheap. Whats it cost to buy an eyedropper, a small bottle and keep it in your med cabinet?
Boy, did I make a turn off the freeway or what? :eek:

"nail fungus"? Do you mean the red rust streaks running down the topsides from a nailed together boat where the fastenings are rusting?

If so, you dig out the putty and coat with a paint containing lead. Such as "red lead". Seal the fastening and reputty.

Ethylene Glycol is "hydrosporic" meaning, it will attrack water molicules. One of the conditions needed for rot is a stable moisture content.

I'm not Chemist, nor do I play him on TV

Boy, did I make a turn off the freeway or what? :eek: Various people here and elsewhere have advocated using ethylene glycol to treat various skin conditions. Before you go down that route you might want to read this MSDS (http://www.jtbaker.com/msds/englishhtml/e5125.htm) .

The health effects listed include (emphasis mine):



Inhalation:
Vapor inhalation is generally not a problem unless heated or misted. Exposure to vapors over an extended time period has caused throat irritation and headache. May cause nausea, vomiting, dizziness and drowsiness. Pulmonary edema and central nervous system depression may also develop. When heated or misted, has produced rapid, involuntary eye movement and coma.
Ingestion:
Initial symptoms in massive dosage parallel alcohol intoxication, progressing to CNS depression, vomiting, headache, rapid respiratory and heart rate, lowered blood pressure, stupor, collapse, and unconsciousness with convulsions. Death from respiratory arrest or cardiovascular collapse may follow. Lethal dose in humans: 100 ml (3-4 ounces).
Skin Contact:
Minor skin irritation and penetration may occur.
Eye Contact:
Splashes may cause irritation, pain, eye damage.
Chronic Exposure:
Repeated small exposures BY ANY ROUTE can cause severe kidney problems. Brain damage may also occur. Skin allergy can develop. May damage the developing fetus.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders, eye problems, or impaired liver, kidney, or respiratory function may be more susceptible to the effects of this substance.

I am the discoverer of this pharmaceutical wonder, and have had a good many testimonials from satisfied users. I completely eliminated athlete's foot and toenail fungus over 15 years ago. I cured my balanophosphitis (diaper rash under the foresking) to the amazement of my urologist. During the three years my beloced Eleanor was bedridden, we kept her skin free of breaks or bedsores with it. I have had reports of cures from people for whom Lamosil® had failed. To me, it makes more sense to put something on your toes than to treat by taking something internally.

What a great thread. Are we all drinking this weekend or what?
Ya gotta love how someone wants to know if anyone ever used a certain epoxy on eBay
and now we are learning of others balanophosphitis.

God bless the WBF. ;)

back to the subject at hand!

folks like WEST, MAS. Progressive epoxy, System 3
start with the raw resins and curing agents and modify them for selected properties

the 'bottom feeders' take the raw resins in bulk and just repackage them.
