| Note: Reported physical properties are based on test specimens cured at an elevated temperature, 180°F (82°C).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 150-180°F (66-82°C). Support of the part may be required to prevent part deformation during the heat curing process. |
