Application:   Normac NR-70LVHS is applied thru heated plural component equipment such as the Normac SFLP-A Processing Machine. The SLFP-A Processing Machine has the ability to be dialed in on ratio based on mas not fixed volume, this means better physical properties.Typical operating temperatures are approximately 65oC (150oF).

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-70LVHS sprayable urethane system. See "Normac Surface Preparation Guide for Urethane Coatings".

NR-9500: A two component, single coat air curing solvent based primer.
NR-9600: A two component wash primer base for NR-9500.
900R:  A two component, air curing rubber based primer.
EP-100: A two component 100% 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).
