MavCoat ESD Static Dissipative Urethane Coating

Where MavCoat ESD Is Used

• Electrical assembly
• Circuit board handling
• Avionics areas
• Static sensitive manufacturing/packaging
• Clean rooms/Labs

Read Before Specifying

• Do not apply without MavTints pigment.
• Do not apply at a temperature not recommended.
• ESD flooring is only part of an electrostatic charge management solution.
• Do not make partial mixes.
• Do not apply over loose or unsound concrete, asphalt or bitumen substrates, glazed tile or nonporous brick and tile, magnesite, copper, metal, polyesters, or elastomeric membranes.
• Moving joints and shrinkage cracks may reflect through the system. Joints that are designed to move may reflect through the finished flooring system if they are not honored.
• Applying thicker than recommended or allowing material to pool may affect the electrical readings.
• Tire marking may occur.

Substrate Requirements

Concrete and coated concrete surfaces must be sound, clean, dry and free of dirt, dust, grease, oil, silicones and other contaminants that may affect adhesion. A suitable moisture barrier must be in place for slabs on grade; the MVT rate must not exceed three pounds per 1,000 square feet per 24 hours per ASTM F1869 and slab relative humidity must not exceed 75% per ASTM F2170, otherwise MavCoat MVB may be required. New or bare concrete must be cured a minimum of 28 days, diamond ground or shotblasted to a CSP 1-3 profile (SSPC-SP13/NACE 6 or ICRI Guideline No. 310.2), and primed with an epoxy tinted a similar color to the topcoat. On previously coated surfaces, thoroughly sand or grind the existing coating with 60 grit sandpaper or diamonds and clean it; if the prepped surface completely covers the concrete, is smooth and insulative, proceed with MavCoat ESD. Air, surface and material temperatures should be 60° – 85°F; higher temperatures and humidity shorten pot life and working time.

Mixing and Installation

Pre-mix Part B with a drill and Jiffy-type blade at low speed, slowly add Part A and mix well, then add the mixed resin to the Part C filler and mix slowly to wet out the light filler and reduce dusting, mixing for 3 minutes or until uniform. Add 1 pint of premixed MavTints per gallon and mix 3 additional minutes until streak free; never mix more than one kit at a time. Cut in edges with a brush, applying thin around obstructions and at the base of coves, since material on vertical surfaces will run and pool. Pour into a roller pan and apply with a 3/8” nap roller at 600 sq. ft./gal. in parallel paths, agitating the pan frequently because the Part C filler can settle, then back-roll perpendicular in a V-shape pattern to spread the material evenly and remove roller lines. Minimize time between tie-ins and break at control joints or natural breaks. For best results, finish roll on spiked shoes in the same direction as the original passes; the material will not flow out, so visible defects will cure in place. Do not back-roll coating that has begun to tack up, which can cause orange peel texture or a whitish haze.
