VANGUARD 200B is an oil concentrate, water emulsifiable corrosion preventative. It is specially formulated for coating phosphated and painted parts such as hinges, bolts, screws, brackets, fasteners, etc. It contains a special additive system that provides a durable self-healing corrosion resistant film. The film is clear and transparent.
VANGUARD 200B is applied as a water emulsion. It is normally applied in dipping operations. VANGUARD 200B Provides a film that has self-healing properties on phosphated parts and components. Salt spray protection is superior to conventional water-soluble rust preventative oils. Phosphated parts coated with a water emulsion of VANGUARD 200B will pass 96 hours in neutral salt spray (20% VANGUARD 200B emulsion coated parts will pass +240 hours). VANGUARD 200B will perform properly when the phosphate coating is within its specified coating weight but it will not make up for an inadequate phosphate treatment.
The system should be charged with water (the total hardness of the water should not exceed 300 ppm as calcium carbonate), leaving enough room in the tank to make a 10-15% emulsion (10-15% VANGUARD 200B, 85-90% water). Begin agitation, then add VANGUARD 200B slowly. WHEN MIXING, ALWAYS ADD THE VANGUARD 200B TO WATER, NEVER THE REVERSE. The VANGUARD 200B emulsion temperature should be 130-150oF at the time of application. Mechanical agitation (not air) is recommended when treating parts to ensure uniform coverage.
