Evonik Launches EXP 8018-1

New finer grade matting agent from the ACEMATT product group.

EXP 8018-1 is a new wax-treated, precipitated silica matting agent in the portfolio of Evonik’s Coating Additives business line. 
 
This finer grade matting agent was developed specially for applications where super-fine surface haptics combined with high transparency are targeted. 
 
The main application areas are high-performance waterborne and solventborne coatings for wood and plastic applications. 
 
The multi-purpose character of EXP 8018-1 enables its usability in various coating systems. It is suitable for both pigmented and clear formulations. 
 
The finer-grade, wax-treated EXP 8018-1 was developed for anti- settling stability in clear coatings and supports high surface quality aspects. 
 
It has excellent dispersibility behavior and a very fine cut of grindometer value. 
 
Due to its easy dispersibility, customers do not require other high-shear equipment to incorporate the matting agent into the formulation. 
 
The silica must be stirred in with low- shear energy at the end of the manufacturing process, which can be achieved with a lab stirrer or dissolver. 
 
As a result, it is possible to use this product as a final addition (post-addition) to adjust the gloss level.
