adhesive curing light alternatives

Looking thru the product MSDS may help you identify the chemistry and you could compare their chemistry to other processes.

You will probably need a shorter wavelength source than the dental light you tried, these can be expensive, depending on the power density you need. The energy density may need to be quite high since you have a lot of solids in your solution.

5-6KJ/cm2 between 200 to 400nm is possibly in range for speed curing.

Try ebay

Before you need to make sure you are wearing appropriate protection for your eyes and skin.

Here are some other possible technologies and tinkering you may try:

Deuterium lamps

Xenon lamps (Possibly a powerful photo flash or stroboscope with the UV filter removed)

multi chip LED's down to 230nm

Mercury lamp

Tanning lamp

Thanks for your input and advise Gigaconcept. I have not tried to get the MSDS from the company yet but, will try that first. The links that you supplied have been very helpfull. I will try looking on E-Bay also.

Thanks again.

It is a pleasure to help.

Can you disclose the company who manufactures this product?

Hi Gigaconcept,

5-6KJ/cm² - if deposited as flashlight - will melt down steel surfaces.

So may be it should read mJ?

Is this thought as the lamps power x time or is this only the UV-B part of the spectrum?

Some ordinary lightsource that certainly will work for a test is a TIG welder.

But be very careful to protect your eyes and skin!!!

This an exerpt from the paper liked.

This is a ceramic printing and curing research project, perhaps not applicable for metals or plastics.

Loctite has a nice selection of units: Some are lower priced than your $2000 model. Jon Boyle On-Hand Adhesives www.gluguru.com

Dear, Gigaconcept,Rhade,and gumb17jb,

Maybe I should give you a little more info to come up with some answers. Being a Dinosaur in the way of using Forums please excuse me for seeming a little vague.

The Company's name is "Heimerle- Meule" in Germany and they offer a product to the jewelry trade named Colorit. If you buy their products they sell lights to cure them. One such light is a hand held and the other is a type of small light box. It is mainly used for coating gold and silver as an alternative to High fire enamel which is basically glass melted onto 18K gold or better.

From my short expereince with the product, without using their lights to cure it; a basic Black light will somewhat cure the darker colors but , not the lighter ones. I have used a Dental hand held blue UVB light and it will cure both but, not to it's full hardness. I am told that once it is totally cured you should not be able to scratch the surface but, I can which leads me to believe it's not being cure properly with these methods of curing lights.

Also, the pieces being cured should be placed into Glycerin to cure the oily smear layer left on the surface after the colors cure or you end up with a matt finish on the surface to be polished. It seems easier to cure it in Glycerin and knock a step out because, it is very time consuming to polish.

I hope I have given a little more info for all of you to work with.

Once again thank you for all of your imputs, it has been a great help in my knowledge. HemiHi

Hi Hemihi,

if you have a look at the website of the company you will find the data for a pure thermal cure of these "colors".

I suppose that these materials consist of a polymer that is filled with hard and colored mineralic or ceramic particles.

Your use of a dental light means your target is small.

We bought a very simple toaster oven then punched a hole in it's top for a halogen lamp socket. We chose a 600 watt, 120 volt projector bulb. Put an aluminum foil reflector under the target. Total cost was maybe $100. It cures fast and it heats. We use it daily and the $15 bulb lasts a year.

Hello Rhabe and BobG,

First Rhabe- I looked on the companies web site and the only thing I saw was "Intense Blue Light" for curing Colorit products. Maybe I just couldn't find "Thermal"? So is what your telling me is, it can be cured by just a Halogen high watt light bulb that will put off some degree of heat (no blue light like UVB needed)?

Second BobG- The Toaster Oven sounds great! Should it be my understanding that this device that you made and use cures this "Colorit" product?

Thank you all, Mark

Halegen lights do have a fair amount of UV in their spectrum.

It is filtered out for regular lighting.

In UV curing lights, the IR and Vis part of the spectrum are filtered.

My Translux EC dental curing source uses a EFR64634 15V 150W halogen lamp.

If you look at Osram ,GE, you will get line powered lamp datasheets with unfiltered UV output. Not much is on their sites, you may need to call.

Lots of people make UV curing lamps, shop around. Some will let you try before you buy, others will evaluate a sample of material that you send to them.

the curing light on the market mainly consists of two types according to the difference of light: the light is white and the blue light.

i found this site they provide many reasonable price for dental curing light hope this will help you.

I bought a Dental Curing Light last week, xlite II Curing Light Widen Wavelength LED,anybody heard this?
