Omyabond 520-FL

Omyabond 520-FL by Omya is a fine, white calcium carbonate (GCC). It is designed for moisture reactive adhesives and sealants (such as PU, SMP or Silicone) in any environment. A very special production process combined with a fatty acid treatment not only result in a low powder moisture as such but also in lower moisture pick-up than standard coated grades of comparable fineness. It can be used as single filler at high filler levels which is easily dispersible and supports low modulus and good workability. Usually there is no need to pre-dry the powder, it allows to-speed up the production/mixing and cooling process and thus helps to reduce total cost. Omyabond 520 is available globally from different locations, the Omyabond 520-FL is produced in North America.
