Surface Modified Wollastonite
Fillers and Extenders
NYCAST U-1 is custom chemically surface modified for application in urethane casting compounds.
It can be loaded in either the polyol or isocyanate side replacing (equal parts) fillers presently being used: glass beads should always remain in the system for viscosity control.
Key Benefits of NYCAST U-1:
Improved impact strength
Improved tensile strength
Improved flexural strength
Reduced settling or hardpanning
Improves surface appearance of the casting |
