The A-701 Yellow and A-702 Green Zinc Phosphate Primers meet the performance standards outlined in Federal Specification T-P-1757A. They also exceed the 800 hours of salt spray fog test (ASTM #B117). Tempo’s Zinc Phosphate and Zinc Oxide Primers are recommended for priming bare metal. These primers provide maximum bonding to bare aluminum and steel. Tempo’s Primers have been the workhorse in the aviation industry for many years. Zinc Oxide has been recently introduced to provide a “safer, healthier” alternative to Zinc Chromate with equal performance. ORM-D requires ground shipping to continental US only – no Air.
