Packaging and storage
For details regarding our packaging options for this product, please contact your local sales representative.
Our products are inert and extremely stable chemically. 
However, due to their high specific surface area, they can absorb moisture and volatile organic compounds from the surrounding atmosphere. 
Therefore, we recommend to store the products in sealed containers in a dry, cool place, and removed from volatile organic substances. 

Even if a product is stored under these conditions, after a longer period it can still pick up ambient moisture over time, which could lead to its exceeding the specified moisture content. 
For this reason, our recommended use-by date is 24 months after date of manufacture. 
Product more than 24 months old should be tested for moisture content before use in order to make certain that ACEMATT OK 412 is still suitable for the intended application.

Application and characteristics
ACEMATT OK 412 allows exceptional surface characteristics with excellent slipeffect, also in pigmented coatings. 
As a result of ACEMATT OK 412s outstanding suspension behavior, ACEMATT OK 412 is especially suitable for use in clear coats.
