When tinting epoxy resin, it may be tempting to add extra pigment for a stronger colour. Yet, exceeding the recommended pigment concentration can lead to issues with your resin piece’s appearance and performance. Here’s a guide to achieving brilliant results while safeguarding your project.
How Pigment Levels Affect Resin Performance
Most epoxy resins are formulated to accept a specific amount of pigment or dye. Exceeding this limit can cause improper curing, leading to tackiness, brittleness, or a cloudy appearance. Typically, up to 5% pigment by weight is a conservative upper guideline for achieving vivid colour without undermining the resin’s key properties. Always check the manufacturer’s recommendation for your particular resin and colourant.
Tips for Reliable Colouring
For deep, vibrant or solid effects, use highly concentrated colourants designed for epoxy—such as Colourfun Liquid Epoxy Resin Colourant. Such colourants deliver strong hues with only a few drops, helping you stay well within the safe limit. Start by mixing a small amount of pigment thoroughly into your resin, then build up if needed, always measuring by weight for accuracy.
When This Matters Most
- Clear or Transparent Casts: Over-pigmenting can turn a crystal-clear piece milky or opaque.
- Functional or Structural Pieces: Excess pigment may weaken the cured resin, especially for jewellery, trays, or coasters that need durability.
