Epoxy Installation Terminology

June 8, 2012

Epoxy.com technical support staff gets asked a lot about epoxy terminology. This page deals with the terms associated with epoxy  installation times.  Specifically “Epoxy Pot Life” sometimes called the epoxy’s “Working Time“, “Tack Free Time“, “Initial Cure”,  and “Final Cure” sometimes called the epoxy’s “Full Chemical Cure“.  Keep in mind that all of the information below assumes that the epoxy has been properly measured and mix. The information is specificall based on Epoxy.com Products, but is typically true about many 100% solids epoxies.

Epoxy Pot Life aka Working Time

The “Pot Life” of epoxy is the time that it takes for it to start gelling in the in the mix vessel (typically a bucket). One important thing to remember is that this is done by a standard which is 200 grams of the material at a given temperature typically 70° F or 77° F. So remember that the bigger you make the  batch of Epoxy.com resin, the faster the batch will set.  See the Epoxy Pot Life Page for more details.

Epoxy Tack Free Time

The “Tack Free Time” of the epoxy is pretty much just what it sounds like.  It is the time that the epoxy is no longer sticky to the touch. When the epoxy is “Tack Free” it can be handle or even walked on if necessary, but you will want to be careful because the epoxy will be very vulnerable to scratching right after it becomes “Tack Free”. The “Tack Free Time” given on the product’s Epoxy.com technical data sheet is also at a specific temperature, typically 77°F.

Epoxy Initial Cure Time

The “Initial Cure” is not the same as “Tack Free“.  Typically “Initial Cure” is about twice as long as the Tack Free Time. Most epoxies have about 80% of the epoxy’s final cure at “Initial Cure“. After the Epoxy’s “Initial Cure” the epoxy is still vulnerable to scratching, but typically strong enough that these scratching will be strictly esthetic and not structural. In cases where time permits and esthetics are essential you may want to wait 1.5 to 2 times the “Initial Cure” of the epoxy before you allow heavy traffic or rougher handling. The primary outside force that can effect this time is temperature. The epoxy’s “Initial Cure” time assumes the temperature indicated on the technical data sheet, or 77° F. if not otherwise specified.

Final Cure aka “Full Chemical Cure”

When the epoxy has reached its “Final Cure” it has achieved the strengths indicated on the Epoxy.com technical data sheet. It also means that the epoxy has reached its full water resistance and full chemical resistance. This time also is also effected by temperature, similar to all the other times listed above. One interesting note is that “Final Cure” when the epoxy is 99% cured.  Epoxy will continue to harden for as much as a year.  So  the “Final Cure” for epoxy is like the “28 day” cure on concrete.  It is typically said that the concrete is fully cured in 28 days.  In fact concrete will under the right conditions continue to cure for up to 100 years.

New Epoxy.com Electro Static Dissipative Epoxy

September 1, 2010

Epoxy.com announces a new ESD Epoxy Product

New Epoxy Electrostic Dissipative (ESD) Epoxy Coating

Less Expensive, Easier to Use, More Durable


Epoxy.com Product #677

Electro Static Dissipative (ESD) /CONDUCTIVE COATING


DESCRIPTION

Epoxy.com Product #677 is a pigmented, water-based epoxy coating designed to achieve either an electro-static dissipative (ESD) finish or conductive finish by
modifying the underlying system components and thickness. Epoxy.com Product #677 has very low odor making it suitable for use in occupied
buildings and has high bond strength and adhesion to concrete and other surfaces.

ADVANTAGES

  • Durable, Attractive, Chemical Resistant, Non-Porous, Light Reflective Finish.
  • Low Odor during application and cure.
  • Maintains Electrical Conductivity Performance over the Wear Life of the System
  • Fast Dry and Re-coat Time.
  • Easy Clean-up.
  • Provides an ESD finish in the range of 1,000,000 to 1,000,000,000 ohms resistance when used over a non-conductive
    primer/basecoat or a conductive finish in the range of 25,000 to 1,000,000 ohms resistance when used over a conductive primer/basecoat.

CONSIDERATIONS

  • Substrate must be above 50°F and relative humidity below 85% for proper curing.
  • Substrate must be free of dirt, waxes, curing agents and other foreign materials.
  • Excessive moisture in the substrate will require a moisture vapor control treatment.

TYPICAL USES

Concrete floors and walls in electronic component assembly areas, data processing, military/aerospace, pharmaceutical plants,
hazardous industries (dust or explosion hazards). For use in any areas where the build-up of static electricity is a concern or a spark-proof floor is required.

APPLICATION

SURFACE PREPARATION

Surface Preparation is the most critical portion of any successful resinous flooring system application. All
substrates must be properly prepared and tested for moisture as outlined in Epoxy.com
Surface Preparation Guidelines.

INSTALLATION

Mix Part B of Epoxy.com Product #677 prior to combining. Mix 1 part Part A with 2 parts Part B. Epoxy.com Product #677 at a rate of 200 ft2
per gallon per coat with a short nap roller. Care should be taken to avoid
puddles. Two coats are necessary to insure uniform coverage.

AVAILABILITY

Contact Epoxy.com Customer Service Department at 321-206-1833

Maintenance

Remove animal fats, oil, grease or soap film promptly to reduce slipperiness. Epoxy.com Product #677 can be cleaned with neutral soaps and detergents.
If long periods of heavy traffic cause wear patterns reapply as need.
Anti-skid materials will reduce the effectiveness of the static dissipative
properties of this material.  Do not use aggressive anti-skids. It is
impossible to get an accurate reading of the conductivity of the floor if
anti-skids are used.
