Rapid Cast Accelerator (Drum) for Investment Casting

Rapid Cast Accelerator (Drum) is a liquid silica, high-quality accelerator for precision investment casting use.

This specialized liquid additive is designed to enhance the performance of thixotropic slurries used in conjunction with fused silica flour, significantly reducing the number of dips required in shell building—often by 35–50% compared to traditional systems. It helps maintain stable slurry viscosity over time, improving working time and reducing binder maintenance. The accelerator also promotes cleaner burnout and easier shell removal, frequently eliminating the need for caustic shell cleaning. With high silica purity and compatibility across both colloidal silica and ethyl silicate binder systems, Rapid Cast Accelerator supports uniform slurry consistency, strong shell formation, and reliable performance in high-temperature casting environments. Foundries producing aerospace, medical, and industrial castings use this accelerator to speed up production while preserving shell strength and surface quality.

Ships in 55 gallon drums. Larger orders available in 275 gallon totes.
