What is the recommended mixing ratio of white pigment powder to resin for a bright white color?

Dec 08, 2025

Hey there! As a supplier of White Pigment Powder for Resin, I often get asked about the recommended mixing ratio of white pigment powder to resin for a bright white color. It's a crucial question, especially for those who are into resin art, crafts, or industrial applications where a vibrant white hue is desired. In this blog, I'll break down everything you need to know about getting that perfect bright white color in your resin projects.

Understanding the Basics

First off, let's talk about what we're working with. White Pigment Powder for Resin is a finely ground powder that, when mixed with resin, imparts a white color. Resin, on the other hand, is a viscous liquid that hardens over time, creating a durable and glossy finish. The key to achieving a bright white color lies in finding the right balance between the two.

Factors Affecting the Mixing Ratio

There are several factors that can influence the ideal mixing ratio of white pigment powder to resin. These include the type of resin you're using, the desired opacity, and the specific application.

Type of Resin

Different resins have different properties, such as viscosity, curing time, and transparency. For example, White Phenolic Resin Powder has its own unique characteristics compared to other types of resin. Some resins may require more pigment powder to achieve the same level of whiteness as others. It's important to read the manufacturer's instructions for your specific resin to get a general idea of how it behaves with pigment.

Desired Opacity

The level of opacity you want in your final product also plays a role in determining the mixing ratio. If you're looking for a completely opaque white, you'll need to use more pigment powder. On the other hand, if you want a more translucent or tinted white, you can use less.

Application

The application of your resin project can also affect the mixing ratio. For example, if you're using the resin for a thin layer, such as a coating or a glaze, you may need less pigment powder compared to a thicker pour, like a resin casting.

Recommended Mixing Ratios

Based on my experience as a supplier, here are some general guidelines for mixing white pigment powder to resin for a bright white color:

For a Slightly Tinted or Translucent White

If you want a subtle white tint or a more translucent effect, start with a ratio of about 1% to 2% pigment powder by weight. For example, if you have 100 grams of resin, you would add 1 to 2 grams of white pigment powder. This will give you a soft, pastel-like white color that still allows some of the resin's natural transparency to show through.

For a Semi-Opaque White

For a semi-opaque white, increase the ratio to 3% to 5% pigment powder by weight. So, for 100 grams of resin, you would add 3 to 5 grams of pigment powder. This will result in a more solid white color that still has some translucency, making it suitable for projects where you want a bit of depth.

For a Completely Opaque White

To achieve a completely opaque white, you'll need to use a ratio of 6% to 10% pigment powder by weight. For 100 grams of resin, this means adding 6 to 10 grams of pigment powder. This is ideal for projects where you want a bold, bright white color that covers any underlying surfaces completely.

Testing and Adjusting

Keep in mind that these are just general guidelines, and the actual mixing ratio may vary depending on the factors mentioned earlier. It's always a good idea to do a small test batch first before committing to a large project. Here's how you can do it:

Prepare your materials: Gather a small amount of resin, white pigment powder, and a mixing container. Make sure you have a scale to measure the ingredients accurately.
Mix a small batch: Start with a low ratio, such as 1% pigment powder by weight, and mix it thoroughly with the resin. Use a stir stick or a mixer to ensure the pigment is evenly distributed.
Observe the color: Pour a small amount of the mixed resin onto a test surface and let it cure. Once it's dry, evaluate the color. If it's not as white as you'd like, add a little more pigment powder to the remaining resin and mix again. Repeat this process until you achieve the desired color.
Record your results: Keep track of the mixing ratio and any adjustments you made so you can replicate the results in future projects.

Tips for Mixing

Here are some additional tips to help you get the best results when mixing white pigment powder to resin:

Use a scale: Measuring the ingredients by weight is more accurate than using volume measurements, especially when dealing with small amounts of pigment powder.
Mix thoroughly: Make sure the pigment powder is completely dissolved in the resin to avoid any clumps or streaks in the final product. Use a stir stick or a mixer to mix the resin and pigment for at least 2 to 3 minutes.
Work in a well-ventilated area: Resin and pigment powder can release fumes, so it's important to work in a well-ventilated space to avoid inhaling any harmful chemicals.
Wear protective gear: When handling resin and pigment powder, wear gloves, goggles, and a mask to protect your skin, eyes, and lungs.

Conclusion

Finding the right mixing ratio of white pigment powder to resin for a bright white color is all about experimentation and understanding the factors that affect the color. By following the guidelines and tips outlined in this blog, you'll be well on your way to creating beautiful, bright white resin projects.
