RD 75 FR
PRODUCT DESCRIPTION:
RFD 75 is a very low viscosity, rapid setting, rigid urethane compound. This system will cure quickly to a hard, tough, impact
resistant casting. RFD 75 is non-sensitive to moisture after cure and will readily bond to itself if stage pours are required. The
one to one volume mix ratio makes the system readily adaptable for machine mixing and dispensing. RFD 75 is recommended i
n applications where a “thermoplastic feel” is desired.
