Primer 50 is a single-component, solvent-based activator designed to accelerate the cure of Hernon™ anaerobic adhesives and sealants, particularly on passive metals, inert surfaces, or in bond gaps, and under temperatures below 15°C. It appears as a green liquid with a viscosity rated as low, a specific gravity of 0.79 at 25°C, and dries in no more than 5 minutes. The product meets ASTM D5363 (Grade N) and MIL-S-46163A Grade F requirements. It is highly flammable, contains acetone and an amine/copper salt chemical type, and has an on-part life of 30 days. Storage must be in unopened containers at 7°C to 29°C, away from oxidizing agents and combustibles. Dispensing requires nitrogen or argon pressurization, and it should not be mixed directly with adhesive.
Primer 50 is a single component, non-CFC solvent-based product designed to promote the cure speed of Hernon® anaerobic adhesives and sealants. Primer 50 is used where increased cure speed of Hernon® anaerobic adhesives and sealants is required. It is especially recommended for applications with passive metals or inert surfaces and with large bond gaps. It is particularly recommended for cure conditions below 15°C. Primer 50 meets the requirements of ASTM D5363 (Grade N) and MIL-S-46163A Grade F.
