Safety, Handling and Toxicity

Flammable liquid. See Normac NR-8310 Material Safety Data Sheet (MSDS) for specific handling and safe working practices.



Normac NR-8310 must be thoroughly mixed before use. Brush, roller or spraying on degreased grit blasted metal (minimum anchor pattern 50 microns) to a minimum thickness of 12.5 microns to a maximum 25 microns. For solvent sprayable urethanes, allow 30 minutes to a maximum of 7 days for application.  For castable urethanes allow 1 hour minimum drying time to a maximum of 8 hours for casting operations.  Should you exceed the 8 hours, refresh the primed surface with Acetone or Ethyl Methyl Ketone.  Allow solvent to evaporate.  Perform the casting operation within 2 hours of refreshing.


Dilute with Acetone only at the rate of 3 parts mixed primer to 1 part solvent for spray applications.
