PR-2050 Class B is a rapid curing compound designed for aerodynamic smoothing and gap filling applica- tions. It has a service temperature range of - 65°F (-54°C) to 250°F (121°C), with intermittent exposures up to 400°F (204°C). This product has low shrinkage and cures to a 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 prob- lems that can be experienced with more brittle sealing compounds. PR-2050 Class B is a two-part, epoxy cured, Permapol® P-3.1 polythioether compound. The cured product will not degrade after limited exposure to jet fuel and avia- tion gas, nor with limited contact to diphosphate ester based hydraulic fluids. PR-2050 Class B exhibits excel- lent adhesion to a wide variety of properly prepared aircraft surfaces. The following tests are in accordance with PRC- DeSoto Standard.
