A few basic rules should be followed when using our DURAVIN AVP-PM Water Based Vinyl Primers. Because its basic solvent is water, along with appropriate additives and emulsifiers, this primer must be handled differently than conventional solvent based systems.

One person should perform the following:

1. Dilute this primer at least 1:1 and as far as 2:1 (water/primer) with water.

2. Maintain the alkalinity or pH at 9.5 or above by an occasional addition of AMP-95 or ammonia.

3. Primer should be agitated by use of a small stirrer to reduce the possibility of any settling.

4. Inside of the primer tank must be coated so that the AVP does not come in contact with bare steel, the resultant rust will react with the emulsion causing a separation and settling. Use a plastic tank or coat steel tank with a two component epoxy paint or polyurethane.

5. Parts should be dry, by means of a blow-off device or dry-off oven prior to priming. To prevent contamination from final rinse the pH of the final rinse stage should be monitored.

6. Parts must be thoroughly clean and free of all grease and oil.

With proper handling AVP-PM will give excellent results, with greater economy than solvent bases systems, and will eliminate the possibility of fire due to hazardous volatile fumes.
