Processing instructions

Add to the grind before dispersion.

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

Haziness caused by low temperatures can be eliminated by warming the product. This does not affect the performance properties of the product.

Stir before use!
