Sikafloor®-2350 ESD NA

ELECTROSTATIC DISSIPATIVE EPOXY FLOOR COATING

Sikafloor®-2350 ESD NA is a two-component ESD epoxy coating system utilizing carbon nano tube to impart electrostatic control properties to a variety of substrates in conjunction with ESD footwear, including existing non-conductive substrates. ANSI S20.20-2021 compliant resistance range to meet specific industry and DOD standards. Sikafloor®-2350 ESD NA will impart static dissipative resistance readings as a stand-alone topcoat on top of standard epoxy concrete primers such as Sikafloor®-161, Sikafloor®-160, Sikafloor®-165 FS, Sikafloor®-1620, or a conductive system when used in conjunction with Sikafloor®-220 W.

  • Conforms to ANSI S20.20-2021. Static dissipative range 1.0x106 to 1.0x109 ohms per ANSI S7.1/ASTM F150.
  • Conforms to ANSI/ESD 97.1 with compliant footwear or shoe grounders. Conductive range of 2.5x104 to 1.0x106 when used with Sikafloor®-220 W NA Conductive Primer.
  • Body voltage generation under 15V with ESD compliant footwear per ANSI/ESD 97.2.
  • Consistent resistance measurements are observed when testing in accordance with standard methods.
  • Sikafloor®-2350 ESD NA will impart static dissipative resistance readings as a stand-alone topcoat on top of a standard epoxy concrete primer such as Sikafloor®-161, Sikafloor®-160, Sikafloor®-165 FS, or Sikafloor®-1620.
  • Maintains electrical conductivity throughout the entire thickness of the system.
  • Does not depend on relative humidity for conductive properties.
  • Tough, smooth, non-porous surface is easy to clean and maintain.
  • Abrasion resistance.
  • Meets or exceeds ANSI 326.3-21 for DCOF. Please contact Sika Flooring Technical Service for individual values.

Application steps

SUBSTRATE PREPARATION

The concrete surface must be clean and sound. Remove any dust, laitance, grease, oil, dirt, curing agents, impregnations, wax, foreign matter, coatings and detritus from the surface by appropriate mechanical means, in order to achieve a profile equivalent to ICRI/CSP 3-4 for floors and ICRI/CSP 1-3 for walls. The compressive strength of the concrete substrate should be at least 3,625 psi (25 MPa) at 28 days and at least 218 psi (1.5 MPa) in tension.

MIXING

Mixing ratio - A with pigment : B = 2:1

 

Premix each component separately, including the Sikafloor® Epoxy Pigment Pack to ensure product uniformity. For all colors, add one (1) quart Sikafloor® Epoxy Pigment Pack for every 2.8 US gallons of Component A resin and mix at low speed (300-450 rpm) for three (3) minutes until a uniform color is achieved using a drill fitted with an Exomixer® or Jiffy type paddle. Be careful not to introduce any air bubbles during the mixing process. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for an additional three (3) minutes. Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.

 

It is very important to mix components A and B for at least 3 minutes to stabilize the color. 

APPLICATION

Apply Sikafloor®-2350 ESD NA in a single coat at a thickness of approximately 20 mils (covering 80 square feet per mixed gallon). Applications thinner than 18 mils will result in an 'orange peel' texture. Use a notched squeegee and a 3/8-inch quality solvent-resistant roller cover for application. Apply at a uniform thickness for a consistent appearance. For back-rolling, use the largest roller practical for the application size. Keep application areas as small as possible to avoid long tie-in times and ensure there are enough resources to manage the area efficiently. Back roll the material to distribute it evenly, making one final pass with the roller at a 90° angel to the application direction.
