No-Bake Process

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.

With HA-International, you can choose from a full line of refractory coatings, release agents, and metal cleaners to compliment your No-Bake operation.
