Secondary Chemical Containment

February 7, 2017

You can easily build containment in the middle of an existing slab

Building a secondary containment structure in the middle of an existing facility is very common and effective way to protect the facility structurally as well as protect the environment.  It is very easy to do.  Here is how:

  1. Grind the area where the curb will go to bare concrete – www.epoxy.com/surfaceprep.aspx.
  2. Drill holes into the concrete and fasten #4 bar into the concrete with Epoxy.com Product #2006 – www.epoxy.com/2006.aspx – Gel Adhesive. Allow Epoxy to cure overnight.
  3. Form the area to receive concrete curb.
  4. Coat the floor area in the bottom of the forms to receive the concrete for the curb with Epoxy.com Product #2007 – https://www.epoxy.com/Epoxy_Fresh_Concrete_to_Hardened_Concrete_2007.aspx – Wet to dry concrete adhesive. Pour your concrete before the #2007 becomes tack free. That will make it as if the curb and the concrete floor had been poured at the same time.
    1. An alternate method to this is to install concrete brick around the area bonding in place with Product #2006. This will help to reduce waiting for the concrete to cure if you use the poured concrete method above.
  5. Allow the concrete to cure – www.epoxy.comsurfaceprep.aspx.
  6. Cove the inside of the containment curb with Epoxy.com Product #720 – https://www.epoxy.com/720.aspx – coving resin allow to cure overnight.
  7. Prime the inside of the containment area with Epoxy.com Product #12– www.epoxy.com/12.aspx  – Chemical Resistant Primer, and allow to cure overnight.
  8. Install 2 coats of Epoxy.com Product #633 – www.epoxy.com/633.aspx – Chemical Resistant Novolac Epoxy Coating.

Summary

Doing an effective job of building secondary is easier than you may think. For more information visit our website at http://www.epoxy.com, call our technical support department at 352-533-2167 or email us at info@epoxy.com.

NOVOLAC EPOXY WALL COATING – 100% SOLIDS

January 23, 2017

High Chemical Resistance Epoxy Coating

Epoxy.com Product #633W

Introducing highly chemically resistant Novolac epoxy wall coating.  Bring your chemical resistance to new heights. Apply this Novolac Epoxy Wall Coating on walls in thicker coats, with less runs.  Same great chemical resistant Novolac Epoxy as Product #633, but thicker.

Description

Epoxy.com Product #633W is a 100% solids epoxy novolac coating ideal for harsh chemical and solvent environments. “W” designates High Viscosity formulation for improved film build on vertical surfaces. Epoxy #633W can be used as a seal coat for various Epoxy.com products and systems where extreme chemical resistant performance is required, such as secondary containment, solvent storage, pump pads, trenches, chemical process areas, and other high exposure areas.

Epoxy Novolac Wall Coating is 100% solids, modified amine adduct cured epoxy novolac (novolac epoxy) resin.

Advantages

  • Exhibits excellent resistance to strong acids, alkalis, and most industrial chemicals and solvents.
  • Can be applied in occupied facilities.
  • Can be applied in cool damp conditions.
  • Can be rapidly re-coated in ambient conditions.

Considerations

Good surface preparation is one of the most important parts of the installation of a high end coating. Be sure to follow our
Surface Preparation Guide before installing this product.

Installation

  1. Review and follow epoxy installation tips
  2. Properly prepare the substrate.
  3. Mix small batches of the material with 2 parts “A” and one part “B”, being sure to completely mix for 3 min. Mix only what you can use in half the potlife. Remember the bigger the batch the faster it will setup in your bucket
  4. Installation methods will vary from job to job. Typical application is by brush and quality roller.
  5. Contact Epoxy.com Technical Support with any questions that you have.
