Abstract
The invention relates to a solid porous article containing sub-micron functional additive particles held together using discrete sub-micron polymer binder particles. The porous article preferably also contains a majority of primary active particles in the 1 to 300 micron range. The solid porous articles are used to separate, precipitate, and/or trap components of a fluid that passes through the porous article. The solid porous articles are used to separate and trap components of a fluid that passes through the porous article. Preferred binders are polyvinylidene fluoride resins, such as Kyblock® resins from Arkema Inc.
