can be used as one component of microparticle retention systems
in the “wet end” of paper manufacturing. Typically, a high surface area
colloidal silica is used with a cationic starch, poly-acrylamide, or other
cationic polymer to flocculate cellulosic fibers for use in the papermaking
process. An optimized process will result in higher retention of fiber and
improved water drainage on the web.
– Increases the dry strength of paper products.
