Pigment pigment liquid Copper 1 L

Why copper liquid pigment suits high-volume resin and wax production

This 1 liter liquid copper pigment is built for manufacturers who need consistent color strength across large batches rather than a single test pour. The format suits workshops running epoxy resin, polyurethane, gypsum, decorative concrete, plastics, and candle lines that have moved from craft-scale to conveyor-style output. The pigment sits within the Pigments Liquid section, which gathers non-migrating concentrates that resist bleeding and keep an even tone throughout the lifetime of the finished item.

The copper liquid pigment is most widely used in polymer and mineral materials: epoxy castings, decorative concrete panels, gypsum molds, and polyurethane blanks for souvenir and interior pieces. The metallic copper tone is popular in resin jewelry, furniture inlays, and construction imitations of metal finishes. A separate demand comes from candle production, where the pigment is stirred into melted wax to produce a rich copper shade without bleeding onto the surface once the candle sets. It also finds occasional use in soap making, where a small amount lends a warm metallic sheen to the base.

Dosage depends on the density of the carrier and the desired depth of color: epoxy resins typically need between 0.5 and 3 percent of the total mass, waxes and paraffin usually take 1 to 4 percent, while gypsum and concrete can require up to 5 percent since the mineral matrix absorbs part of the pigment. The pigment should be added while mixing the base with the hardener, or into a melt kept below 80–90 degrees Celsius to avoid altering the shade through overheating. Stir thoroughly until the color is fully uniform, with no streaks or clouding.

The copper shade blends well with other tones from the same line, allowing gradients and transitional colors within a single pour. For a cooler metallic undertone it can be combined with Blue liquid pigment, while a warm wood-toned palette pairs well with Wood brown liquid pigment. For contrasting decorative accents next to the metallic base, many producers reach for Black Agate liquid pigment ultra.

Keep the pigment in a tightly sealed container, in a dry space at room temperature, away from direct sunlight and freezing conditions. Before drawing from a large 1 liter container, give it a good stir, since minor separation can occur after extended storage.

Copper resin coaster batch

Epoxy resin base 600 g

Hardener 300 g

Copper liquid pigment 12 ml

Fine mica powder 4 g

Combine the resin base and hardener in the ratio recommended by the manufacturer, mixing slowly for about three minutes until no streaks remain. Add the copper pigment together with the mica powder and stir for another minute until the color turns even with a soft metallic glow. Pour the mixture into silicone molds, pass a heat gun briefly over the surface to release trapped air, and leave to cure at room temperature for 24 hours away from dust and moisture.
