Refractory Coatings
Carpenter Brothers, Inc. is proud to offer HA International refractory coatings. HA-International provides a complete range of refractory coatings to meet all of your metal casting needs. Refractory coatings are used on molds and cores to enhance the surface finish of the casting and reduce casting defects that occur at the sand-metal interface.
Refractory coatings consist of refractory minerals, carrier/reducer, binder, suspending agent, and special additives. The most typical carriers in metal casting are water and isopropyl alcohol. Refractory Coatings can be used on molds and cores.
Some of the benefits of using a refractory coating are: reduce or eliminate metal penetration, reduce or prevent burn-on, prevent erosion of sand by molten metal, smoother surface finish, improve overall casting quality, reduce scrap, and lower cleaning costs. However, the benefits of a refractory coating are only achieved if the proper coating has been selected and it has been correctly prepared, applied, and dried. Improperly selected, prepared, or applied coatings can result in poor casting finish or coating defects. Carpenter Brothers, Inc. and HA International are here to help you choose the proper coating for your application. We will show you the appropriate way to prepare, apply and dry the coating resulting in repeatable excellent castings.

About Us
Carpenter Brothers, Inc. is the leading supplier of equipment, consumables, and technical expertise for the metal casting industry. Founded in 1917, by Everett and Milton Carpenter, the brothers were able to use their unique foundry experiences to solve the problem of the day: a reliable sand source. They got their foot in the door by selling natural bonded molding sand, which was mined by hand, loaded into horse-drawn carts, and then delivered to customers. Not only did they sell the sand, but their technical expertise was readily available for all customers, big or small, to help manufacture the best castings. After surviving The Great Depression, Carpenter Brothers, Inc. slowly increased the number of products it distributed and expanded its sales territory into what it is today.
Carpenter Brothers, Inc. has committed itself to its customer's success by providing exceptional service to go along with the superior products and equipment they supply. With multiple warehouses around the United States we can get you the products you need when you need them. Our logistics team can handle getting your order to you by truck, plane, or train.
