The casting resins, which are usually commercially available, usually have a heat resistance between 70° C. and 100° C. If the resin is colored, it is possible that the temperature resistance will decrease. Therefore, it is common practice, especially for epoxy tables, to apply a layer of clear epoxy resin afterwards. As seen from the results above, transparant resin dyes have a slight increase in exposure time on a monochrome LCD 3D-printer like the Elegoo Mars 2. For the opaque resin colorants at maximum loading level, an additional 1,5 seconds was needed to cure a layer of 0,1mm. Please note this could be different for each printer. On printers with an RGB screen, the increase in exposure time is expected to be significantly higher. This is a gorgeous holographic vinyl for resin. The silver is especially pretty because it actually captures all the colors of a true holographic prism. It also comes in green, gray, rose gold and other finishes depending on the look you are trying to achieve. Once you’re sure that your resin and hardener have been mixed together adequately, it’s time to throw in your pigment powder. We recommend using a small spoon and adding a full, level spoon full of pigment powder to your container of resin. Liquid paint is particularly suitable as a colorant for epoxy resin because it is very easy to mix with the liquid resin. The liquid epoxy paint dissolves very evenly in it and ensures a homogeneous coloring of the casting resin.
There are products out there specifically made for coloring your resin. Liquid colorants are easy to use and will give your pours a saturated look without very much colorant. A little goes a long way. We really like the basic colors from this line. You add these in after your resin and hardener have been mixed. Just remember to stay to your mixing ratio of no more than 10% colorant to resin (whether you are using resin alcohol ink, epoxy dye, mica powder pigments, liquid epoxy paint, glitter powders or any other colorant). It is always best to add a bit at a time before adding more to achieve the look you are going for. Two resins were selected for this experiment, Liqcreate Premium Tough and Liqcreate Clear Impact. Both resins are clear. Premium Tough will change in a milky white polymer upon curing, while Clear Impact remains colorless. Both materials should be easy to color, due to the natural color of the polymers itself. Three main points of focus will be: Figuring out how to color resin castings can be tough, but since we know that pigment powder and liquid resin dye are among the most popular and most effective, let’s have a look at some of the best liquid dyes and pigment powders the world has to offer. Remember that not all brands of resin dye products are created equal, therefore choosing a low-quality product could result in your workpiece being ruined. Always ensure that paint, pigment, dye, or chalk you choose will produce a decent color effect.

Similar tests have been done with Liqcreate Clear Impact resin in combination with resin colorants from 3DJake. In the first tests, a similar colorant loading level of 2,5% was used in Clear Impact. With the opaque pigments Deep Blue and Light Grey, adhesion issues occured at 2,5% loading on the Mars 2 MSLA 3D-printer. First layers were difficult to adhere to the platform with the addition of the pigments. Two changes were initiated after the first tests. The loading level was decreased to 1,25%. Next to that the printer was changed to the Photon Mono SE, as this printer has a aluminum platform, it is easier to get adhesion. After these changes, it prints were looking good at an exposure time of 16,0 seconds, compared to 11,0 seconds for the original Clear Impact resin. You can use a holographic nail pigment to achieve a color shift in your resin, and what some resin artists do is actually mix a holographic pigment with a color shift medium to get a really unique result. Then mix the ready paint into the epoxy resin. Start with a small amount of color pigments or liquid color concentrate and mix well. Repeat this step until the desired color intensity is achieved. Another option to get a less opaque, more dominant holographic color shift effect, is to use a holographic vinyl. With vinyl though, remember it typically comes with a clear layer on top you will have to peel off before pouring resin on.
As a rule, the epoxy resins available in specialist shops are temperature resistant up to temperatures between 70 and 100 degrees Celsius (158 °– 212 ° Fahrenheit) without any problems. However, the exact value depends on the products used and the additives added. In some cases, mixed-in dyes and pigments can have a negative effect on the temperature resistance of the castings produced. For this reason, it can make sense to cover tables with colored epoxy resin with a protective layer of transparent epoxy resin before use. Today we're going to chat about the quality colorants for resin and what you can add into epoxy resin to get different color effects. Watercolors have a very low pigmentation. This means that only in very large quantities would they actually color the resin. In addition, the components epoxy resin – watercolor/watercolor are very difficult to mix. Now that you know what pigment powders and liquid dyes are, what the alternatives to these types of dying agents are, what the differences between them are, and what the best product for each respective dying agent is, it’s time for you to go out and put your newfound knowledge to the test. Remember to always work with gloves and a face mask when working with resin, and that your work area is well ventilated. For the test purpose, the maximum recommended loading level of 2,5 weight percentage was chosen and tested. Right after weighing the liquids colorants in the resin, it was apparent that the colorants are very compatible with both Liqcreate resins and are easy to mix in, by just shaking the resin bottle with colorants for a minute.In 2005, Charlene completed her Wellness Diplomas in Therapeutic Aromatherapy and Reflexology from the International School of Reflexology and Meridian Therapy.
