Supercharge Your Green Sand System Green sand systems work harder and last longer with TRUBOND®. These sodium bentonite grades mull in quickly and undergo a controlled hydration to develop a stronger, more elastic adhesive. TRUBOND delivers excellent green compressive and hot strength properties and maintains its working bond in repetitive exposure to high heat loads and metal temperatures.
