Mixing pigment powder with resin involves combining the powder thoroughly into a small amount of resin, then incorporating that mixture into the larger batch of resin. This ensures even color distribution and prevents clumping.
Here's a step-by-step guide:
-
Start with a Small Amount of Resin: Pour a small quantity of your resin into a separate mixing cup. This will act as your "pigment carrier."
-
Add Pigment Gradually: Introduce the pigment powder to the small amount of resin. Add it gradually, mixing thoroughly after each addition. This prevents clumping and ensures even distribution of the pigment.
-
Mix Thoroughly: Use a mixing stick or spatula to mix the pigment powder into the resin completely. Scrape the sides and bottom of the container to ensure no powder is left unmixed. You're aiming for a smooth, consistent color.
-
Incorporate into the Main Batch: Once the pigment is fully mixed into the small amount of resin, pour this colored resin into your larger batch of resin.
-
Mix Again: Gently and thoroughly mix the colored resin into the larger batch. Be careful not to introduce too many air bubbles during this step. Continue mixing until the color is consistent throughout the entire batch of resin.
Important Considerations:
- Powder Quantity: Start with a small amount of pigment. You can always add more to achieve the desired color intensity. Adding too much powder can affect the resin's curing process or properties.
- Mixing Tools: Use clean, dry mixing tools to avoid contamination and ensure proper mixing.
- Safety: Wear appropriate safety gear, such as a respirator or dust mask, when handling pigment powders, as some may be harmful if inhaled.
