Cold Box
Carpenter Brothers, Inc. proudly supplies HA International cold box resins. Their portfolio includes:
Phenolic Urethane Cold Box systems (PUCB) – The PUCB process utilizes an amine gas to catalyze the reaction between a phenolic resin and an isocyanate resin to produce a urethane bond. HAI’s PUCB resins are the best in the business for high core strengths, long mixed sand bench life, humidity resistance, and release characteristics that can’t be matched.
Phenolic Esters Cold Box systems (ECP) – Ester-cured phenolic cold box process uses two components; a resin and a curing agent. The resin (Betaset) is an alkaline phenolic resole in water, and the curing agent is the vapor of a volatile ester, methyl formate. The betaset resin offers higher strength development and excellent dimensional stability, both highly desirable traits in making high valued castings.
Carbophen systems – Carbophen is a water-soluble phenolic resin system cured by passing carbon dioxide (CO2) gas into a sealed core box. The resin is the sole binder component added to the sand for making molds and cores. In addition, carbophen has been formulated to contain no reportable formaldehyde making this system more environmentally friendly.

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. Our technical sales and engineering staff all have experience in the industry, so when you buy from Carpenter Brothers you gain access to all of our knowledge.
