Carpenter Brothers, Inc. proudly supplies HA International no-bake resin systems.

The Phenolic Urethane No Bake (PUNB) process utilizes a catalyst reaction to produce a urethane bond that cures under ambient conditions without the addition of heat, gas, or vapor. In addition to PUNB resin systems, HA-International has the industry’s most comprehensive lineup of Furan No-Bake (FNB) and Phenolic No-Bake (PNB) Acid Cure No-Bake resin systems.

HAI’s acid cure resins go from high FA content, low water, zero nitrogen to furan modified resins that offer the lowest cost while maintaining the expected performance in the mold-making process without compromising the casting quality.

Our comprehensive product selection allows you to select the right product to meet your specific application. HAI can accommodate any casting application with nearly every combination of furfuryl alcohol, water, urea, and plasticizer chemistry. Regardless of your particular goal, we are confident that one of our acid-cure no-bake resin systems will get the job done.

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.
