Processing instructions

Add to the grind before dispersion.

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

Handling & storage

Keep away from freezing.

At low temperatures, reversible turbidity can occur.

When stored in an original unopened packaging, the product has a shelf life of 48 months from the date of manufacture.
