Epoxy.com  CONDUCTIVE consists of 100% solids epoxy, carbon fibers, and aggregates to produce a fluid, self-leveling mixture that is spread with a flat trowel. Applied in two coats, Epoxy.com  CONDUCTIVE produces a 1/16 to 1/8 inch conductive floor. A 1/4 inch conductive surfacing can be achieved with additional applications.

Surface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared as outlined in Epoxy.com  - TECHNICAL SUPPORT BULLETIN - SURFACE PREPARATION. Specific attention should be paid to the following:

Also, the temperature and humidity conditions of the area to receive the flooring system should be checked. An optimum room temperature of 75ºF with a minimum slab temperature of 50ºF is required for proper cure of the resin flooring system.

A. Guideline System Requirements for 1000 ft² 1/16 inch

Epoxy.com  Conductive Qty./ 1000 ft²

1. Epoxy.com Product #671 Conductive Primer Sealer 5 gallons

2. Epoxy.com  Product #672 (1^st coat) 20 gallons

3. Epoxy.com  Product #672 (2^nd coat) 20 gallons

B. Recommended Batch Quantities

1. 11/2 gallons Epoxy.com  Product #672

Estimated Batch Coverage: 75-85 ft²

A. Priming

Epoxy.com , Inc. recommends that every flooring system be installed with a primer to insure maximum adhesion to the prepared substrate. Priming will also help to seal air in the concrete and prevent outgassing and air bubbling in the finished system.

1. Mixing Epoxy.com  Product #671 Conductive Epoxy Primer

a. Stir each component prior to mixing.

b. Mix one (1) parts by volume of Part A (Base) with one (1) part by volume of Part B (Hardener) for three minutes with a low speed electric drill mixing paddle.

c. Thinning is not generally required.  Do not thin primer without first speaking to Epoxy.com Technical support department for alternatives first. If thinning is required, add no more than one pint of urethane or laboratory grade xylene per gallon of epoxy at time of mixing.

d. Mix only that amount of material that can be used in 40 minutes.

2. Application

a. Pour primer onto the prepared concrete.

b. Spread with either a flat trowel or squeegee to a coverage of 250 ft² per gallon.

c. Back roll with a short nap roller.

3. Allow Primer to sit for 30 minutes. Conductive slurry may be applied to wet primer for up to five (5) hours after primer application. If primer is to be allowed to sit overnight or prolonged periods, broadcast lightly with dry silica sand.

B. First Coat: Conductive Flooring

1. Mixing Epoxy.com  Product #672

a. Stir each component prior to mixing.

b. Mix two (2) parts by volume of Part A (Base) with one (1) part by volume of Part B (Hardener) for three minutes with a low speed electric drill mixing paddle.

c. Mix only that amount of material that can be used in 30-40 minutes.

Note: Use a slow speed drill to mix Epoxy.com  Conductive Epoxy. Mixing at high speeds can break up conductive fibers. Damaging the carbon fibers will damage the conductivity of the system.

2. Application

a. Immediately pour portion of mixed material onto floor in a strip and spread at a rate of 45-50 ft² per gallon. Apply as a flow coat with a conventional cement finishing trowel. Trowel or spread material in one (1) direction only to achieve a smooth flow coat of material approximately 30 mils thick. Leave a "wet line" or puddle of material between batches to avoid "knit-lines" in the finished system.

Note: Termination points at the end of the day should be made at doorways, expansion joints, etc. If it is not possible to terminate at these points, 2" masking tape should be placed in a straight line at the ending point. Carefully trowel the material up to and slightly over the inside edge of the tape. Allow material to cure for about thirty (30) minutes and remove the tape.

b. Do not back roll or use a spiny roller.

c. Allow floor to cure overnight or a minimum of 8 to 10 hours.

C. Second Coat: Conductive Flooring

1. Mix Epoxy.com  Conductive Epoxy as outlined in First Coat.

Note: Use a slow speed drill to mix Epoxy.com  Conductive Epoxy. Mixing at high speeds can break up conductive fibers. Damaging the carbon fibers will damage the conductivity of the system.

2. Application

Immediately pour portion of mixed material onto floor in a strip and spread at a rate of 45-50 ft² per gallon. Apply as a flow coat with a conventional cement finishing trowel. Trowel or spread material in one (1) direction only to achieve a smooth flow coat of material approximately 30 mils thick. Leave a "wet line" or puddle of material between batches to avoid "knit-lines" in the finished system.

1. Finished thickness of Epoxy.com  Conductive is approximately 1/16 inch. If a thicker system is required, build thickness prior to application of Epoxy.com  Conductive Epoxy.

2. Do not open to light traffic for 48 hours. Full chemical cure is achieved in 5 to 7 days.
