Application:   Normac NR-95HT is applied thru heated plural component equipment.  The spray gun is both impingement and static mix with an adaptor to fit Graco RAC IV spray tips to suit all types of applications.  This system uses air pressure to purge the mix chambers and tips.  No solvent is required during application.  Typical operating temperatures are approximately 65oC (150oF).  Air requirements for the main pumps is 100 lbs. Normac NR-95HT can also be used as a castable product.

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-95HT Sprayable Urethane System. See "Normac Surface reparation 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).
