Sherwin-Williams says its new high-heat finish is one of only four approved products available globally to meet the rigorous MIL-PRF-14105 standard, having received approval from the Army Research Lab (ARL). The finish is heat resistant to 1,400°F and can withstand wide fluctuations in temperatures from extreme cold to extreme heat without cracking, chipping or flaking. Available in a variety of colors, this corrosion-resistant finish also dries to touch within one hour of application, can be applied directly to metal and does not require a high film thickness.
The company also offers MIL-DTL-53022 Type V enhanced corrosion epoxy primer, an aerosol version of its Type IV 2K liquid spray epoxy primer. According to Sherwin-Williams, this is the first epoxy technology available in an aerosol to be approved by the ARL. The fast-drying primer meets the specification requirements of 1,000 hrs of salt spray and 40 cycles of cyclic corrosion, and can be used under CARC topcoats or in virtually any application where corrosion resistance is needed.
Applications for both MIL-PRF-14105 and MIL-DTL-53022 include military, heavy equipment and automotive end-uses.
