Recommended addition level

As supplied calculated on inorganic pigment: 15.0 - 40.0 %.

Recommended addition level for co-grind: 0.3 - 2.0 %.

Processing instructions

In case of foam build-up during dispersion, use a highly effective but also compatible defoamer concentrate (for example, TEGO® Foamex 8050).

Add to the grind before dispersion.

Handling & storage

When stored in an original unopened packaging, the product has a shelf life of 36 months from the date of manufacture.
