We Believe in Giving You the Right Bronze Powder
Color concentrates, or master batches as they are also called, are frequently used to tint plastics. In special cases, they can be directly colored. Metal pigment pastes in mineral oils that are compatible with polymers or plasticizers or preparations in granulate form (pellets) in PE are used here.
If gold-bronze pigments are used, due to the high processing temperature, the use of coated, temperature resistance pigment powders is recommended.
Masterbatch is the intermediate step in the process of using metallic effect pigments to color plastics. Masterbatches consist of metallic pigment (=coloring agent) + carrier + additives.
The metallic pigments are incorporated in a relatively high dosage in the masterbatch and subsequently in a low dosage in the final plastics by injection moulding or extrusion. Besides polystyrene, other polymers, such as ABS, PVC, LDPE and PP are also used as carriers.
In general, AVL offers pastes with mineral oil for masterbatch. Our dust-free pastes are easy to disperse, odorless, and are highly compatible with plastics. The mineral oil is specially selected for its low-odour properties. Other solvents are available upon request.

Copper-gold powder with a coarse particle size, uniform flake shape, and a high level of shimmer. It has a pronounced metallic feel, and its coarse particle size contributes to an eye-catching shimmer effect. This type of powder is widely used in industries like oil-based coatings, immersion coating, and printing.

This series of copper-gold powders that are finely produced with computer control. This process effectively removes both the coarse and fine powders from the product, resulting in a more concentrated particle size distribution. This refinement leads to better coverage and higher gloss. These powders find applications in various industries, including gravure printing, screen printing, paints, and injection molding.
