I Need Help

05/21/2017 10:41 PM

I Knew I should Of listened more in school! This formula Has been giving me fits.I Recently Got into the Business Of sublimation Printing on T-Shirts Ceramic Tiles,Mugs And ect!But The issue seems to be the Coating of the items before they can Be sublimated..I Have The Formula But I am Not Sure what This formula Consist Of...I Know They are a Polymer Combination any additional Info Would be greatly appreciated so That I can try and make the coating for my products so my business can be successful ..

Ouch, your asking us to reverse engineer the result of a completed chemical process.

You may get lucky if someone here is able to provide a link to the process that results in the end result you have posted, but reverse engineering is......unlikely with only this bit of information.

The "R" seems to be a misprint (among many others in the post).

The R is for pirate chemists . . .

Not a misprint. The R is what one might call an algebraic term in the description of an organic molecule. It could stand for an H, a C or a more complex hydrocarbon, see this page.

These coatings belong to the class of polymers comprising epoxies, acrylics, polyesters and polyurethane. I believe the polyurethane dominant compositions mixed with epoxy resin and a blocked polyisocyanate could be what that formula was trying to say ! Now The blocked Polyiscyanate is another issue..I really do appreciate all the Help on the subject I can get.I Have tried the Digi coating as someone in this discussion suggested and it wasn't what I believe or would consider a quality product,I Have wasted so much money On sprays,Paper,Urethane, poly,epoxy resin and the list goes on,I am very close but Now i am stumped and need a little help!!

blocked polyisocyanate - 1K product, no pot life (unless you heat the pot to cure temperature).

http://www.coatings.covestro.com/en/Technologies/Solventborne/Blocked-Polyisocyanates

All the information you most likely need can be found through the above link, and a quick telephone call to the providers of this product.

Thank You So Much James,I really Do appreciate All the Help and Understanding of My Frustration It has really been a Nightmare Trying to Become a Chemist!! LOL! I Have also Read That Epoxy Is a lot Cleaner when Curing,than Other Polymers ..I also Know it is more expensive But i would rather spend a little more than Breath the toxic fumes LOL! I just wonder if I took Like 4 Oz of Epoxy,4 Ml Of Catalyst ( Hardner ) and Maybe A little H20 and start with that as a Base,and kinda go from there Maybe adding a few drops of other Polymers for different applications if i would be on right Track or completely off base!

If you are breathing fumes off any polymerization, you are doing it badly. Use a fume hood, glove bag, or the like to prevent general contamination of the work space with potentially hazardous fumes, also to limit the effects that variable humidity can have.

As to the direct water addition concept, what have you read in that regard? I suppose it can weaken the final product, and also slow the curing just a bit, but it could lead to something you would rather just throw out and start over if over done.

If relying upon thermal setting of the epoxy by driving off the water, you could end up with something like epoxy sponge if things are bad enough. Not good IMHO.

...another one....

If you're thinking about manufacturing your own, you need a good chemist and some money, it's complicated....

Yes It Is a combination Of Thermosetting Polymers Combo With Other additives to thin the base. This Formula has been so difficult for me to put together and I thought with having this as a Starting point would make it easier if i reached out to someone who could understand the code and had knowledge in this field.I didn't realize that it would be just as hard,I thought each Letter stood for a Polymer or a Additive and all I needed to do was post an someone who could read it would be Okay 1 2 3 WAH LAH!! I Guess it is Back t the Drawing board..I Do Appreciate all the Ones who took time out to help!! Any Advice would be very Helpful! Because My knowledge is very Limited

Well, it ain't beef arts. Old Milwaukee, tastes just like the refreshing taste of the Mississippi River. I have consumed this and other Wisconsin favorites in the past, but my liver is no longer up to it, any more than I would take a wooden boat, and go raiding the coastline of England.

Well if it was that easy the formula would be readily available and the coatings would be cheap....It should be obvious by now, that is not the case...These companies that make and sell the coatings no doubt hired a chemist to develop the formula they use, and as such, they are proprietary in nature and protected by patent or copyright...You might be able to buy the rights to use some patented formulas...It seems that every surface demands a certain chemical formula, so finding a combination that will work well in your particular application, is likely by trial and error...

It is free if she contacts the suppliers of blocked isocyanates. Doh!

Basically, if she does not raised the printed pattern to the correct temperature to cure the thing she printed on the T-shirt, then it is just smearable goop.

Follow directions to the letter, and all will be well.

R is a placeholder for different kinds of radicals which may be attached to the molecule....

"Illustrated Glossary of Organic Chemistry

R group: An abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule. Sometimes used more loosely, to include other elements such as halogens, oxygen, or nitrogen. R is an abbreviation for radical, when the term radical applied to a portion of a complete molecule (not necessarily a free radical), such as a methyl group. Should not be confused with R (the gas constant), R (the one-letter abbreviation for the amino acid arginine) or R (a designation of absolute configuration)."

R = ?R =

CH3
Toluene

R = H

Benzene

R =

Ph
Biphenyl

Thank you So Much For Your Help,It Is All Greatly Appreciated!! I was Seriously at my wits end, because although I do Understand that others did their research before me and some feel like why should I help them,But I Have seriously Put in Months and Hours and Hours Of research and Time energy and money! I can also see their side of it But I Have Honest Put in Effort and work! This has Provided me with a ray of hope and Hopefully I will be able to finally put together something i can use! Hopefully I can give a Positive Update!

That appears to be a poly-urethane coating. I hope you also know how to remove it?

I was almost tricked into seeing that as a homo-protein, one that is made up all the same amino acid. The extra oxygen, I think definitely places this in the polyurethane class.

Why not buy them in all ready made from top manufacturers.

Then when you have a lot of experience,starting a small way with a tiny R&D to develope your own.

There are companies that will take a small sample, scan it and let you know the chemicals in the sample. Also the approximative amounts.

Use an unmarked container.....
