| Note: Physical properties obtained from test specimens post cured per recommended procedure.In order to achieve maximum physical properties, a post cure with heat is required. BJB recommends 24 hours at ambient temperature, 77°F (25°C), followed by 16 hours at 160° - 180°F (71° - 82°C). Support of the part may be required to prevent part deformation during heat cure. |
