Overview
Boeing provides PPG Aerospace/PRC DeSoto PR2050B1-2, PR-2050 Class B as a rapid curing compound designed for aerodynamic smoothing and gap filling applications. It has a service temperature range of -65°F (-54°C) to 250°F (121°C), with intermittent exposure up to 400°F (204°C). This product has a low shrinkage and cures to sandable hardness in at least one hour at 77°F (25°C) or above. When cured, PR-2050 Class B remains flexible, reducing potential cracking problems that can be experienced with more brittle sealing compounds.
