1. Liquid Pigments: Liquid pigments are commonly used to color epoxy, polyester resin, and gel coat. They are available in various colors and can be mixed to create custom shades.
2. Mixing Ratios: The recommended mixing ratios may vary depending on the brand and type of liquid pigment used. Always refer to the manufacturer's instructions for specific guidelines. However, as a general rule of thumb, the following percentages can be used as a starting point:
Epoxy Resin: Typically, 1% to 6% liquid pigment by weight of the total epoxy resin mixture is used. Start with a smaller percentage and gradually increase to achieve the desired color intensity.
Polyester Resin: Liquid pigments are generally added at a rate of 1% to 6% by weight of the total polyester resin mixture. Again, start with a lower percentage and adjust as needed.
Colored Gel Coat: Liquid pigments can be added to colored gel coat at a rate of 1% to 3% by weight of the total gel coat mixture.
Non-Colored Gel Coat: Liquid pigments can be added to non-colored gel coat at a rate of 1% to 6% by weight of the total gel coat mixture.
3. Mixing Process: Here are the general steps to mix liquid pigments with epoxy, polyester resin, or gel coat:
Measure the required amount of resin or gel coat according to your project needs.
Shake the liquid pigment bottle well to ensure uniform consistency.
Add the liquid pigment to the resin or gel coat slowly, stirring continuously to achieve even distribution.
Mix thoroughly until the pigment is fully incorporated and the desired color is achieved. It's essential to mix the pigment thoroughly to avoid streaks or uneven coloring.
4. Testing and Adjusting: Before applying the colored resin or gel coat to your project, it's advisable to perform a small test batch to assess the color accuracy and intensity. If the color is too light, add more pigment in small increments until the desired shade is achieved. Conversely, if the color is too dark, you can add more resin or gel coat to lighten it.
5. Safety Precautions: When working with liquid pigments and resinous materials, always follow safety precautions provided by the manufacturer. This may include wearing gloves, safety glasses, and working in a well-ventilated area to minimize exposure to fumes.
By following these guidelines, you can effectively use liquid pigments to color epoxy, polyester resin, and gel coat for your projects. Remember to experiment and adjust the ratios to achieve your desired color and finish.
