Techsol PRIM – Polymer Enhanced Colloidal Silica

Techsol PRIM – a high-quality, polymer enhanced colloidal silica primary slurry binder for precision investment casting use.

Formulated to deliver faster drying, stronger green strength, and cleaner burnout, Techsol PRIM is ideal for high-performance foundries looking to reduce dip counts, minimize downtime, and accelerate shell building without sacrificing quality. Foundries casting aerospace, stainless steel, and industrial components rely on Techsol PRIM to shorten production cycles while maintaining tight tolerances and smooth casting surfaces.

This polymer-enhanced colloidal silica creates slurries that set quickly and build shell strength early in the drying process. The result is improved handling, reduced cracking, and shells that are easier to knock out after pouring. Despite its fast-setting nature, the polymer burns off cleanly during dewaxing and firing—leaving no ash, residue or adverse reaction. Techsol PRIM is compatible with common refractory systems including fused silica and zircon.

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