Description

Unlike conventional liquid or wet painting, powder coating is a dry finishing process. Fine, grounded up particles containing pigments and resins are sprayed onto a metal substrate using an electrostatic spray gun. Unlike liquid paints, the powder coating process does not involve the use of any solvents, making it an almost pollution free application!! In addition, unused, excess powder can be recycled and reused making this the greenest of all paint applications!!! The powder coating process involves three basic steps, part preparation or pre-treatment, powder application, and curing. However, there are other steps involved prior to these that are essential. Often times before a manufactured part can be powder coated; it is necessary that specified areas are masked off to be free of any coating. We use a variety of masks such as silicone caps and plugs, high temperature green tape, spot masks and even steel templates depending on the masking requirements, size of the part, tolerances allowed, and quantity of parts to be masked. Caps and plugs are specifically used when masking threaded holes and pem nuts. Threaded areas are always masked off to prevent powder build up which interrupts the final and proper assembly of a coated part. All caps and plugs are removed before the finished product reaches the customer. This is done during the final inspection and packaging of the coated parts. (Shown above is a large chassis that has over 100 threaded areas that must be capped and plugged) Masking is also done on parts that require paint free areas for electrical grounding contact. Moreover, many parts even require that the entire interior surfaces be free of powder. This involves the use of specifically sized masking tape, custom diameter spot masks, plugs and caps, or a combination of all. We only use the highest quality, highest temperature masking tape so that the application and removal is easy without leaving any adhesive residues on the finished product. This also results in clean, straight lines between where the masked edges meet the coated surface. The range of masking performed at Coatings Applications is limitless. The photos below will give you an idea as to how wide this masking spectrum is. Obviously, all masking is done based on specific customer requests and requirements. (Example of spot masking, with a specific area masked off for electrical grounding) (This part requires all holes be masked off using custom sized spot masks) (Finished product showing spot masked areas free of coating) (This project required that the entire interior surface be masked off and free of any coating)
