产品说明:

RIGID-CAST 8017 A/B is a rigid, 80 Shore D, two-component high impact and high strength castable urethane. RC-8017 A/B has been designed to meet a wide variety of part making applications that range from electronic enclosures to mechanical parts. This system is very light in color and its translucency makes it extremely easy to color. RC-8017 A/B can also be demolded in one hour or less, depending on part thickness and mold conditions.

The RC-8017 A/B has a work time of approximately 60 seconds and meter mix dispensing equipment is recommended for processing. BJB offers meter mix dispensing equipment ranging from hand operated static mix systems to air-power operated production systems. Call BJB's technical representatives to provide processing information assistance.

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 180°F (82°C). Support of the part may be required to prevent part deformation during heat cure.
