Application:   Normac NR-6511D is applied through heated plural component 1:1 equipment.  The recommended spray gun is a Probler or Gusmer GX-7 with the appropriate mixing nozzle or chamber. This system uses air pressure to purge the mix chambers and tips.  No solvent is required during application.  Typical operating temperatures are between 60oC (140oF) to 71oC (160oF). Spraying pressures should be minimum 2500psi for best physicals.  Air requirements for the main pumps is 90 lbs. Electrical is 220v single phase and 110v.

Surface Preparations and Primers:  Standard surface preparation procedures such as grit blasting to near white metal or acid etching concrete is required for good mechanical bonding of the NR-6511D sprayable polyurea system. See "Normac Surface Preparation Guide for Urethane Coatings".


NR-9500:  A two component, single coat air curing solvent based primer.

EP100/EP200:  A two component, air curing epoxy based primer.

Refer to specific primer/adhesive data sheets.

Coverage: Normac NR-6511D

Theoretical coverage:

34 m2 @ 25 microns (166 ft2/lb. at .001").
