Coloring epoxy resin
Coloring epoxy resin - instructions
The terms epoxy, resin and casting resin usually hides epoxy resin. The most versatile way of tinting this versatile material is with the color pigments , color pastes or concentrates intended by the manufacturer . Then it is ensured that the special composition is coordinated.
But even experiments with other colors are often worthwhile. Especially when it expands the spectrum of possibilities. As always when experimenting there are more or less successful results and often unexpected effects even with small deviations.
Since the commercially available epoxy resins and hardeners differ, we recommend in any case before a larger application to make an attempt with their own starting materials. This is worth it because the material is not cheap and at the same time your own ideal mixture can be found.
Color Pastes for Epoxy Resin, Color Powder and Other Epoxy Dyes:
- Color paste RAL black
- Color paste RAL white
- Special color pastes
- Starter Kit Epoxy Resin (7 Epoxy Resin Pastes)
- Starterset transparent
- Starter set glitter
- Pigments for epoxy resin
Alternatives to special colors
- printer ink
- Airbrush colors
In general, color additives of any kind should be concentrated so that they have as little influence as possible on the curing of the material. In addition, the colors are always added to the finished resin-hardener mixture.
When cured, epoxy resin is usually colorless and transparent. When coloring, this transparency is more or less preserved depending on the color type and quantity.
Practical implementation - coloring of epoxy resin
Step 1: Mix the color
If you want to mix a color, then you should do this before touching the epoxy resin in peace, otherwise the processing time of the finished resin may be in short supply.
Step 2: Mix epoxy
Measure and weigh epoxy resin and hardener according to manufacturer's instructions and mix well. Please also note the information on pot life, ie the time available for processing.
Step 3: Add paint to the epoxy resin
The proportion of color must usually make up no more than 5 to 10% of the finished colored epoxy resin, please refer to the manufacturer's instructions. Start with a very small amount (such as a very small drop) and mix well until the color appears homogeneous . Increase the color addition until you like the color intensity - up to the maximum amount specified. Stir well until no streaks, lumps or the like can be seen. In general, the more fluid the color, the easier it is to stir into the epoxy resin.
Frequently asked questions and answers on the topic
- Color epoxy with acrylic paint? Normal acrylic paints often show deposits on the bottom of the solid resin. But many of the colors that are specifically designed for coloring epoxy resin are also acrylic colors - but more concentrated and with a different material composition.
- Color epoxy resin white? Color epoxy resin black? These two colors are - like many others - also for admixing, however, they never become so opaque (opaque), such as a painted surface.
- Color epoxy resin adhesive? It works the same way, but be aware of the processing time and expect it to take a little longer for the glue to dry completely.
- Dyeing epoxy resin transparent? Dye casting resin - transparent? Epoxy resin usually remains slightly transparent when coloring. Of course, special color pastes are particularly well suited for transparent coloring. Even liquid alternative colors such as printer ink or airbrush ink result in correspondingly small amounts to very transparent results.
- When dyeing epoxy resin use pigments? Pigments often have better UV stability and are therefore a good choice for outdoor applications or wherever the epoxy is exposed to light. The only downside is that it does not mix so easily homogeneously.
- Coloring epoxy resin for terrarium or aquarium? This is not a problem as the epoxy resin does not loosen or wash out after curing.
- Dyeing epoxy resin with food coloring? This is not recommended, because the colors are not lightfast for a long time and also have no suitable composition.
- Coloring epoxy with ink (filler cartridges)? This is possible, but also the light fastness of ink is quite limited, so it depends on the location.
- Colorize epoxy with effect colors? There are several of the special colors with effects, such as glitter. In the alternatives, there are many effect colors, especially among the airbrush inks, which can also be used well in the rule.
