Fumed Silica

• Construction Dry-mix Rheology Additives

  Using Fumed Silica to produce dry-mix compounds helps improve their rheology, mechanical properties, thixotropy, and anti-settling characteristics, enhancing their performance and usability in construction applications.

  Fumed Silica is a versatile additive that produces dry-mix compounds, including one-component membranes, tile adhesives, cement-based mortars, and other construction materials.

  Here are the functions that Fumed Silica serves in these applications:

  • Rheology control: Fumed Silica is a highly effective rheology modifier that can control the flow and workability of dry-mix compounds. It can help increase the viscosity and thixotropy of the mix, improving its ability to adhere to surfaces and maintain its shape during application.
  • Reinforcement: Fumed Silica can also serve as a reinforcing agent in dry-mix compounds. It can help improve the mix’s mechanical properties, such as its tensile strength, flexural strength, and impact resistance.
  • Thixotropy: Fumed Silica can also impart thixotropic properties to dry-mix compounds. Thixotropy refers to the property of a material to become more fluid when subjected to shear stress, such as during mixing or application, and to become more dense or solid when allowed to rest. This property can help to improve the ease of application and reduce the risk of sagging or deformation.
  • Anti-settling: Fumed Silica can also help prevent settling solid particles in dry-mix compounds. This can help maintain the mix’s consistency and performance over time.
