DBE® esters - Foundry Core Binders / Silicate Binders

Resins that hold together the sand in a metal casting mould are called Foundry Core Binders. DBE® esters are being used more and more as they provides significant advantages in these formulations, for example giving increased working time of the mix, and increased tensile strength of the cured shape. DBE® esters are a viable alternative to many of the traditional aromatic solvents, especially in cold-box systems, which are becoming more prevalent as the complexity of shapes increases.
