Techsol 1430 Colloidal Silica

Techsol 1430 Colloidal Silica is a liquid silica, high-quality binder for precision investment casting use.

Techsol 1430 is a 30% solids colloidal silica binder formulated for consistent, high-strength shell building across primary, intermediate, and backup coats. With a specific surface area of 250 m²/g and a stable, slightly viscous dispersion, it offers excellent bonding power and reliable performance in a wide range of refractory systems. The negatively charged, amorphous silica particles are slightly uneven and spherical, promoting strong green strength and shell cohesion while maintaining slurry stability. Its pH of 10.3 and low viscosity (≤10 cP) make it easy to mix and maintain, whether used in manual or automated shell rooms.

Techsol 1430 works well with fused silica, zircon, and other common casting materials. To get the most from this binder, dilute with distilled or deionized water to bring SiO₂ levels to an optimal 27–29%, based on your slurry setup. It’s designed for long slurry life and minimal maintenance—just keep it from freezing and store in suitable containers to preserve its integrity.

Foundries rely on Techsol 1430 for dependable shell builds, consistent viscosity, and strong casting results across aerospace, stainless steel, and precision industrial applications.

Ships in 55 gal drums, 275 gal totes, and tank trucks.
