Hydrochromic ink is a kind of water-based ink,which is also a special ink that can change color from white(color) to transparent when it get wet,and would return back to original color when it get dry,Hydrochromic ink can be used by screen printing,which has been proved get very good effects on Paper and textile printing.

Theoretically,We can add some thickening agent which we could buy it from some normal ink shop.As when we add thickening agent into the ink,which would increase its soluble degrees,and then reduce its liquidity,with which would reduce the time for becoming transparent.

Slurry could be mixed with clear adhesives to make thermochromic/photochromic ink (water-based) and then applied on fabric printing, If you like to make the fabric much more comfortable,which you could add little Fabric softener and curing agent-All need to be water-based, the adding ratio is about 0.1%~0.2%,please note that the dosage of curing agent must less than Fabric softener.

The answer is that the hydrochromic ink would not directly affected by moisture content, as it would only to change color when it directly met water, so not matter how much the moisture content in the air, the ink would not easy to change color without directly activating by the water.

It is not suitable.As thermochromic pigment can mostly bear about 180C~220C as its processing temperature, so it is not suitable to be directly mixed in the ceramic glaze slip, because the processing temperature for glaze slip would be too high for thermochromic pigment,with which is better used on its surface by spraying or by screen printing in the stage of finished product of ceramic.

Unfortunately, the answer is no, because NYG-603 is a kind of solvent-based pigment, although it can be workable in the test, it is not workable for large quantity in the long time, or the water-based dispersion would be easy to be broken, even be cured after a while.Anyway, the solvent-based pigment can not be used in water-based system, and please choose water-based pigment for that, with which there is NYG-603T available.

If the pigment were become wet, there are usually following way could dry it.You could dry it by using oven, The temperature controlled under 100C would be fine.Drying in a ventilated and dry place where away from direct sunlight.Above method based on the precondition that the pigment were not wet in water for a long time.

If our thermochromic pigment mixed with polar alcohol type of solvent, which may cause following issues: 1. Producing the chromatic aberration. 2. The color change effect would be become weak, and the worst is that the pigment could not change color final.

If thermochromic pigment overexposed to UV light, which may ruin the pigment and cause it could not change color., according to experience, thermochromic pigment is better not continuously exposed to strong UV light more than 3 hours.If thermochromic pigment overexposed in a Humidity environment, which may cause it easy to caking, and make it hard to use,, as well as may affect its color change response sensitivity.

There were some customers who like to use big particle size of glowing pigment to make Photoluminescent masterbatch, but NewColorChem doesn’t suggest, because if you use big size glowing pigment to make related glowing masterbatch, which may easy to cuase the friction between the machine and pigment and lead to some chemical reaction, which would finally make the masterbach turn to black color and then could not glow color again.

The answer is  YES, Thermochromic pigment could be mixed in both waterbased ink and solventbased ink, but not for the polar solvent.If for the fabric printing use, please consider to use thermochromic slurry, which is special for textile printing use.Thermochormic powder could be also used in UV ink.

Some customers are curious if the water-based Fluorescent powder could be dispersed in the water, the answer is not, because the water-based powder form could be only dispersed in the water-based varnish/ink/paint etc, but not in the water, if you would like it to be dispersed in the water, then please use the slurry form, with which already in the liquid form.

The answer is yes, but need to be test by customers, because if by pad pad printing, the layer of thermochromic ink would be thinner than by screen printing, which would lead the color of thermochromic pigment would look a little weaker than by screen printing.

Actually,Hydrochromic ink is a kind of ready-to-use water-based ink, which is better used by screen printing ,so usually, it don’t need to mixed any other type of crosslinker.Just when you find  it is a little thick to print, then you could add little clean water as it thinner to dilute it.

The Black color of Thermochromic pigment already widely used by people nowadays, its particle size is about 5um, so with which could be applied on many different fields, just like on fabric by screen printing; on craftworks by spraying; on Baby spoon, toys by injection; even on film by gravure printing.

Choosing the best pigment for a plastics application can be challenging. Typically, the type of plastic to be molded will determine the particular product. If you cannot determine the best candidate from the website information, please submit a technical request with as much detail as possible and our technical or marketing staff will respond promptly.

Fluorescent color converts light to a dominant wavelength or color. Without a light source, there is no color. Phosphorescent colorants store energy and re-emit it when the light source is removed. They are, therefore, visible in the dark for some period of time.

Phosphorescent pigments are commonly referred to as glow-in-the-dark pigments. They have the ability to absorb energy and store it. Once the light source is removed, they begin to give up that stored energy in the form of light. The most common glow is the yellow-green shade that we all know.

Fluorescent’ refers to a pigment that absorbs and reflects more light than conventional colors, resulting in brighter and more powerful shades. The color spectrum moves from invisible, low-energy infrared rays to high-energy ultraviolet rays. The ‘visible light spectrum’, or the colors that we see, are actually in the middle of the range. Normal color absorbs and re-emits a portion of the visible spectrum that matches its principal wavelength, while the remaining colors are absorbed and dissipated as heat. Fluorescent colors use a larger amount of both the visible spectrum and the lower wavelengths compared to conventional colors. They not only absorb and convert light energy of the dominant wavelength, but also the wavelengths of ultraviolet rays and other colors lower in the visible spectrum. As a result, your eye perceives a far more intense color.
