UNIFEN B15 is a CO2-cured resin specifically employed in foundry core making. It is compatible with a wide range of equipment, from simple wooden core boxes to high-speed core shooting machines.
By attaining 90% of its final strength during the gassing phase, it facilitates rapid core production. UNIFEN B15 has been developed specifically for cores requiring high mechanical strength. Its superior moisture resistance—which further enhances its strength properties—allows for the application of water-based coatings. Through these features, it enables the production of low-cost cores with low gas evolution, a critical factor for foundrymen
