Flash Point:  None, Normac NR-85LVHS Part "A" and "B" are both non-flammable in shipping, storage and application.

Application:   Normac NR-85LVHS 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.

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-85LVHS sprayable urethane system. See "Normac Surface Preparation Guide for Urethane Coatings".

Primers:
NR-9500: A two component, single coat air curing solvent based primer used over NR-9600.
NR-9600: A two component wash primer base for NR-9500.
EP-100: A two component 199% solids primer for concrete.
Refer to specific primer/adhesive data sheets.

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