Manufacturers are under constant pressure to improve product performance, consistency and durability while meeting changing technical and sustainability expectations.
Levasil colloidal silica, supplied by Nouryon and available through Chemtrade South Africa, is one of the speciality raw material solutions that can support these goals across a range of advanced formulation applications.
What can Levasil colloidal silica help with?
Levasil colloidal silica can support formulations where surface performance, durability and reliability are important.
Depending on the application and formulation requirements, Levasil can help improve properties such as dirt pick-up resistance, adhesion, abrasion resistance, surface hardness, anti-blocking performance and overall product stability.
This makes it a useful option for manufacturers looking to enhance product performance without compromising formulation flexibility.
Why surface performance matters
In many applications, the surface of a finished product plays a major role in how well it performs over time.
Nouryon’s Levasil material highlights the way colloidal silica particles can enrich the surface and substrate interface. This can help reduce tackiness, improve dirt pick-up resistance, increase hardness and strength, support better substrate adherence and contribute to longer service life in suitable applications.
For manufacturers, these performance improvements can support better durability, cleaner-looking surfaces and more consistent end-product results.
What is colloidal silica?
Colloidal silica consists of a large number of very small particles of amorphous silicon dioxide dispersed in water.
Together, these particles create a large surface area, while their surface charge helps them interact with each other and with other substances in a formulation.
A flexible solution for different formulation needs
Levasil is not a one-size-fits-all product. Nouryon offers a range of colloidal silica grades, allowing manufacturers to select solutions that meet their performance, processing and stability requirements.
This flexibility is especially valuable where customers need to balance durability, appearance, adhesion and surface behaviour in the final product.
