| PPG/TDI Urethane Prepolymer |
 |
VIBRATHANE B 621 is a medium performance polyether based prepolymer which produces a polymer in the 90 Shore A range when cured with MBCA.
The prepolymer is a liquid at room temperature with an isocyanate content of approximately 6%.
Because of its low viscosity, B 621 may be processed at low temperatures to increase pot life.
VIBRATHANE B 621 offers good toughness and abrasion resistance in an intermediate hard urethane, good low temperature properties, and low viscosity. |
