Choosing the Right Epoxy Sealer

May 18, 2015

Having the knowledge of which type of sealer to use is extremely important to the overall satisfaction of the job. There are 3 basic types of epoxy sealers. The first is 100% solids epoxy, solvent based sealants and finally water based sealers. There are also urethane and acrylic sealers.

To understand how each sealant works one must understand how they act as an epoxy. http://www.epoxy.com/primersealer.aspx . The 100% solids epoxy when applied to a floor retains a consistent thickness. Epoxy.com #15 http://www.epoxy.com/15.aspx is the best product for maintaining a clear epoxy sealer without any loss of thickness due to evaporation. If you roll a gallon of material on your floor, when it hardens you maintain the thickness of the full gallon of spread coverage.

Epoxy.com #15 can be used to seal previously installed epoxy and river rock stone on pool decks or walkways. It also seals Epoxy Chip flooring, as well as acts as a binger and sealer to Epoxy quartz flooring. It provides protection, just the right amount of shine and helps to keep the water from permeating the underlying concrete. It also works well inside in garages. It is our most versatile sealer that we offer it works great on concrete inside and when properly installed outdoors.

When you apply a water based sealer or solvated sealer you will consistently loose a percentage of the thickness due to evaporation. Even though this is the case there are times when a 100% solids epoxy may not do exactly what you need it to accomplish. In this case we offer products with different components and viscosity to suit your needs as a consumer.

Epoxy.com #671  is a low viscosity, two component, carbon filled, polyamide modified conductive primer/sealer formulated with special wetting agents to provide maximum penetration into concrete surfaces. Product #671 Primer Sealer is ideal for both new and old concrete surfaces. Product #671 Conductive Epoxy Primer Sealer provides excellent resistance to wear, and can be used either alone or as a conductive sealer or as a conductive epoxy primer when used with Product #674 Electro-Static Dissipating Urethane Topcoat and our Conductive Systems.

Epoxy.com #80 is a solvented clear acrylic solution formulated to create a clear, non-yellowing protective coating. Product #80 ACRYLIC SEALER http://www.epoxy.com/acrylic-sealer.aspx provides a tough, UV and abrasion resistant film that effectively protects surfaces from moisture penetration, staining, dirt, dust, and wear. It is good for both indoor as well as outdoor applications. This works well to seal existing terrazzo floors and as well as slate.

For those in California, who don’t want to use a 100% solid material, we offer Epoxy.com http://www.epoxy.com/High-Solids-Urethane-Coating.aspx Epoxy.com # 441 is free of the health and environmental problems normally found in solvent-based urethanes, while maintaining excellent performance properties. The very low VOCs allows this urethane coating to meet the strict low VOC standards. Epoxy.com # 441 Polyurethane Coating and Sealer provides a matte finish. Product #441 water-based urethane coating and sealer has good chemical, stain, and mar resistance.

Finally the most important thing to remember when you are choosing an Epoxy.com Sealer is to make sure you are using The Right Product for The Right Job. If you would like assistance with your selection please call our Technical Support Line at 352-533-2167 and we will be happy to assist you.

Epoxy Education- The Strengths of Epoxy

June 18, 2012

Epoxy Educational Pages Anouncement:

The newest addition to Epoxy.com Education Pages is “Epoxy Resin Strengths Explained” which explains the 4 primary strengths that are very important for most civil and mechanical engineering applications of epoxy: compressive strength, tensile strength, flexural strength, and bond strength. “Epoxy Resin Strengths Explained” also discusses the test methods to measure these strengths.


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.
