What is Glass Bead / Sand Blasting?
Surface preparation is the most critical step in the Powder Coating process. A clean surface provides for maximum adhesion between the part and the coating. If a surface is not carefully cleaned before coating it may lead to early peeling of the coating, easier chipping of the coating and overall result in a poorly finished part. Therefore we strongly recommend the blasting of all parts before powder coating. Steel parts are typically blasted with a sand like product to remove old paint, rust, mill scale and other contaminants. Aluminum, Brass and other non-ferrous parts also need blasting for the same reasons mentioned above. Because these metals are typically softer than steel we will use glass bead blasting to remove contaminants. Glass bead blast will not harm or alter the surfaces of your parts.
