Abstract
Improved silica based matting agents are disclosed. The matting agents are useful in waterborne coatings composition to provide exceptional properties to a wood based substrate. Films resulting on the coated substrate unexpectedly provide improved chemical resistance, thermal stress resistance, weather resistance, and/or film clarity to the surface of a wood substrate. Methods of making and using the matting agents are also disclosed.
