Processing instructions

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

Add to the grind before dispersion.

Handling & storage

Eventually, the product may exhibit inhomogenities. Before use it should be homogenized by heating up to 40 °C and processed in the homogeneous state.

When stored in an original unopened packaging, the product has a shelf life of 24 months from the date of manufacture.
