One of the companies with the greatest focus on the development and supply of colloidal silica, Advent Silica presents to the metallurgical sector its complete line of products, developed specifically for precision casting, monolithic refractories, fibers and industrial coatings. At the fair, visitors can learn how colloidal silica acts as a high-performance inorganic binder, capable of replacing traditional cement-based binders or resins. The result is higher quality castings, more durable coatings, cleaner processes, and reduced defects in investment casting and molding.
Advent Silica demonstrates, based on research and industrial experience, that its technology offers unique advantages. Colloidal silica is an aqueous dispersion of highly stable silicon dioxide nanoparticles available in different size ranges (3 to 100 nm). This feature allows it to be suitable for multiple applications – from ceramic shell binders in precision casting to cement-free binders in refractories.
The use of colloidal silica translates into high purity, ensuring the absence of metallic impurities that impair performance. Strict control of particle size, solids content, and pH allows for tailor-made adjustment to customer requirements. Another advantage is the versatility of stabilization (sodium, ammonia, etc.), which expands the possibilities of application.
In practice, colloidal silica delivers excellent thermal stability, superior mechanical strength and controlled rheology. For casting, this favors parts with lower porosity and lower incidence of cracks. For refractories, it represents a longer useful life and a reduction in energy consumption, since it eliminates curing steps at high temperatures typical of cementitious binders.
COLLOIDAL SILICA BENEFITS DIFFERENT INDUSTRIES
Advent Silica’s colloidal silica solutions meet the demands of a variety of strategic industries.
- Precision casting/investment casting: high-performance ceramic binders.
- Monolithic refractories and fibers: cement-free formulations.
- Steel, iron and non-ferrous castings: improvement of dimensional quality and strength.
- Industrial coatings and surface treatment: protection and durability.
This amplitude reinforces that colloidal silica is not a simple input, but a transversal solution for the metallurgical chain. Advent Silica has customization capabilities, developing specific formulations — adjusting solids, pH and type of stabilization — according to the demand of each customer and application. Thus, colloidal silica becomes a tailor-made solution, adaptable to both large global foundries and regional refractory manufacturers.
Colloidal silica is a 100% inorganic binder, free of organic solvents and VOCs. This characteristic contributes to cleaner and more sustainable processes, reducing the emission of pollutants and increasing occupational safety. In addition, by eliminating high-temperature curing steps required by cementitious binders, it enables significant energy savings in refractory processes. The products comply with international chemical safety standards, such as REACH and TSCA, reinforcing the environmental commitment and care for the health of workers and consumers.
