Normac NR-8011 Parts "A" and  "B"

Weight of Cured Coating: 29 gm./m2 @ 25 microns 0.60 lbs. per 100 ft.2 at .001" thick

Ultimate Cure:    5 days at 21oC (70oF)

Recoat Times:    Continuous: Maximum 12 hours

Mixed Solids Content: 100%

Flash Point:  None, Normac NR-8011 Part "A" and "B" are both non-flammable in shipping, storage and application. See Material Safety Data Sheet (MSDS).

Application:   Normac NR8011 is applied through heated plural component 1:1 equipment.  The recommended spray gun is a Probler, Gusmer or Fusion gun  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 pressure should be 2500psi minimum for best physicals. Air requirements for the main pumps is 90 lbs. Electrical is 220v single phase and 110v.

Maximum Recoat Times: 18 hours @ 21C.

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-8011 Sprayable Polyurea System. See "Normac Surface Preparation Guide for Urethane Coatings".

Primers:

NR-9500/NR-9501: A two component, single coat air curing solvent based primer.

NR-9600: A two component wash primer base for NR-9500.

EP-100: A two component 100% solids primer for concrete.

Refer to specific primer/adhesive data sheets.

Theoretical Coverage:

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