Applications
SiSiB® PC4150 is especially useful in coatings applications where increased solvent and water resistance, mar resistance, wet and dry adhesion, pigment binding and scrub resistance, films hardness and tensile strength.
The unique structure of SiSiB® PC4150 may make it unusually stable in emulsions. It does not react or form crosslinks until the coating is cast as a film.
