Considering the intense use demanded of most industrial and defense equipment, simply painting the bare metal components won’t suffice. In most cases, they must undergo a rigorous mechanical cleaning and/or phosphate pretreatment process to prepare the surfaces. This ensures the cleanest possible surfaces and the most complete adhesion for whatever coatings will be applied. Without these processes, even the strongest coating may fail to adequately adhere, resulting in corrosion and accelerated wear. At Rhinehart Finishing, we utilize automated and manual blasting equipment for product surface profile preparation and coating removal on various products. We use a variety of media for blasting.
Zinc Phosphate Pretreatment
Our state-of-the-art zinc phosphate pretreatment system offers you the best of all worlds by providing high-quality cleaning and surface preparation. Our zinc phosphate is certified by the Department of Defense System to TT-C-490, Type 1 — a service not only valued by our military clients, but also by our commercial customers.
In this process, parts are treated with an inorganic coat that renders the surfaces inert and smoother than if left untreated. This helps paint or powder adhere to the parts more successfully and with less chance of blistering.
Compared to similar types of pretreatments, zinc phosphate offers numerous advantages. For example, it can be used to pretreat products using a mix of metals without modifying the formula to account for varying rates of corrosion, unlike iron phosphate. This process also provides enhanced protection against oxidation. Because it creates its own coating on metal, it also results in faster and more complete adhesion.
Other Pretreatment Options
We offer additional pretreatment options as well, including chromate conversion of plating. We have a network of qualified and certified plating houses that work closely with us to meet all your needs. Additionally, we are in the process of adding passivation and non-hex chromate pretreatment systems to our facility.
