Alumidust Metallic Powders Are Safer And Easier To Use In Metal Cold Castings

By Stan Alderson


Real metal cold casting is a method in which metallic powders are combined with a suitable soft plastic, or resin, to create a wide variety of different mold castings that look like real metal and weigh about the same as well. Once the resin is heated to a thick consistency, it can either be brushed, also called slush-cast, onto the surface of the mold. After this is left to set, pure resin or, depending on the particular look and application that is required, a resin mixed with metal powder is applied over this gel coat. The advantages of the metal cold cast process over actual molten metal castings are that it is a much faster process and costs significantly less.

Metallic powders used in cold castings produce beautiful colors on the surface of the casting, especially when combined with intricate patterns. Alumidust Metallic Powders are specially made for this method and work great. They are also versatile and very easy to use, whether mixed directly with the casting resin, or slush-cast onto the mold.

Alumidust only needs to be applied sparingly, so a small container of a particular color will last quite a long time. Further, it is a non toxic substance so it makes the whole cold casting process much safer than alternative methods. To make a casting stand out and look bright, the powder should be brushed into a high gloss silicone rubber mold - the glossier the better.

These metallic powders come in an assortment of 28 different colors that include bronze, copper, pewter and gold, which provide many solutions in casting resin for any project. The applications that these powders can be used for are many.

A great way to use these powders is to dust them for making fishing lures of the soft plastic type. The process of creating soft lures is a lot simpler than the making of hard lures; a lot less time is involved and there is no need for specialist or expensive equipment such as compressors, air brushes, or purpose built ventilation.

Soft plastic lures are usually dangerous the paints that are normally used are highly flammable. This isn't an issue with Alumidust powders, which make the entire procedure a lot safer and easier. The process involves first dusting the mold with a brush, rather than the lure itself, keeping in mind that the first color that is applied is the one that will show up first on the lure surface.

The plastic is then heated, and when ready simply poured into the mold. It is allowed to cool until it sets. Next, the clear coat plastic is heated up until quite thin. The lure is dipped into this mixture for a few moments by holding it from the tail end until almost fully submerged. The final steps involve lifting it out to allow the excess liquid coat to drip off, then leaving it to cool and set.
