Nyglos® is a high-purity, ultrafine, high aspect ratio wollastonite.

Wollastonite (calcium metasilicate) is a naturally occurring white, non-metallic mineral with an acicular (needle-like) structure. Due to the mineral’s acicular structure, paint and coatings have improved physical properties and durability.

Because of its high melting point, wollastonite is used in high temperature coatings for thermal stability and high pH to allow it to act as a pH buffer for in-can paint stability. It is commercially successful as a cost-effective extender for traditional inhibitive pigments. Even in non-inhibitive systems, it has improved performance by offering barrier properties, erosion resistance and better flexibility.
