Thermosetting Polymers for Printing

07/27/2009 1:25 PM

Does anyone have any idea on the best type of polymer that could be used in sublimation printing on surfaces like glass and wood...one that is transparent ( and one that is milky ) on setting with a melting point of around 300 degrees centigrade.

i cannot seem to find any type that has the correct properties for the ink to take properly without deterioration of colour and opacity as well as durability against wear. something that adheres firmly and permanently and will not flake or peel off. I have no idea what to use as the properties described online are very vague and unhelpful.

I had leanings towards polyethelyne but i dont know if its right for what i want.

Any help would be greatly appreciated

Polyethylene is a thermoplastic.

Is this ink a "primer" that you will overprint?

Printing on glass could be tricky.

300 degrees C is very hot for any polymer. Why so hot? For how long?

no it is sublimation ink that goes from a solid laser toner to a gas upon being heated, the polymer is meant to be a recepitive medium for this gas and the pigment is trapped within the polymer in the desired design. the ideal temperature would be lower than this but it needs to be non flamable for obvious reasons as the print is meant to be worn. 300 was a high estimate more around the area of 200 degrees. But this temp would only be momentary ( about a minute ) for a transfer to occur. The polymers would be the primers essentially

Any polymer used would wold have to adhere even to very slippery surfaces.

Thanks
