Clearcast Brass Metal Powder is a high-quality metallic filler designed for resin casting, cold casting and composite applications where strength, heat control, and a classic metallic appearance are required. It is particularly well suited to larger castings, helping to reduce exotherm and minimise shrinkage while improving the overall strength and stability of the finished piece.
This versatile powder is ideal for creating realistic cold cast brass effects, offering the look, weight, and surface character of solid brass when combined with compatible resin systems. Its fine particle size allows for smooth dispersion within resins, delivering excellent surface detail and professional-quality finishes across a wide range of decorative and functional projects.
Brass Metal Powder is typically added according to the needs of each individual project. A minimum recommended mix ratio of 1:1 (metal powder to resin by weight) will produce a clear metallic effect, while ratios of up to 4 parts metal powder to 1 part resin can be used to achieve a heavier, more authentic brass finish. As resin types and casting methods vary, small test mixes are always recommended to determine the optimal ratio.
For best visual results, dusting the mould surface with brass powder before introducing the resin-powder mixture is recommended. This technique enhances surface coverage and creates a deeper, richer metallic finish. Different metal powders can also be blended together to create bespoke effects, provided they are thoroughly mixed prior to use. Please note that natural colour variations may occur between batches, which is a normal characteristic of metal powders.
