E1500HN Novolac Epoxy | Superior Steel & Concrete Chemical Horizontal Protection | Secondary Containment

E1500HN is a 100% solids, two component Epoxy Novolac resin designed for concrete restoration and protection in extremely chemical corrosive environments.  E1500HN resin and curing mechanism are based on advanced polymer chemistry, providing the highest chemical resistance of epoxies available today.

E1500N has excellent chemical resistance to many acids, caustics, salts, aromatic and aliphatic solvents.  Designed for use in splash, spillage of aggressive chemicals including 98% Sulfuric Acid and 37% HCL.

Great for secondary containment for wide range of chemicals when chemical contact temperatures below 150°F and used with  E15M Epoxy Mastic Primer as part of a specified system (contact us with chemical exposure requirements for system details at

For primary chemical containment and vertical service protection requirements see E555VN Novolac Epoxy.

Recommended as a resin for restoration of concrete floors, sumps, drainage ditches, loading docks, tanks, ramps, storage silos, pump pads, and other concrete structures subjected to extreme chemical attack.  E1500N can be used as a resin with fiber glass reinforced systems.  E1500N is used as a coating in “seed-in” systems and also used as a “neat” coating.

Available in a 1 gallon kit and Dark Gray color.  May be applied in cold, damp conditions to 45°F with curing down to 35°F

PRIMER:  Recommend as needed  E15m Epoxy Mastic Primer

TOPCOAT: Not typically required but can apply a 2nd coat.

In all cases of surface preparation, the pH should be checked. A pH reading of 7.0 to 8.5 is acceptable.  Also, a Water Dissipation Test should be made on random areas of the floor to determine if the proper degree of porosity has been achieved. Before the installation, the substrate should be examined for moisture. Test for moisture vapor transmission using ASTM F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor using Anhydrous Calcium Chloride. The maximum allowable rate is 3 lbs. per 1,000 square feet per 24 hours. Test for relative humidity in concrete floor slabs using Probes according to ASTM F-2170. This test measures the presence relative humidity of the slab below the surface. The maximum relative humidity should be below 80%.

New concrete must be cured at least a minimum of 28 days before applying a coating. On-grade slabs must have moisture vapor barrier in place. All laitance, sealers, efflorescence, chemical contaminants, grease, oil and other foreign material must be removed.

The prepared surface must be clean, dry and structurally sound.   Recommend mechanical preparation by means of shot blasting or diamond grinding to achieve a CSP-2 or CSP-3 profile, in accordance with the International Concrete Repair Institute (ICRI). The profile should reflect something similar to a 60-100 grit sandpaper. If the substrate is not properly prepared and the appropriate profile is not achieved, failure of the product to adhere to the substrate may occur.

Old concrete surfaces must be structurally sound. Any unsound areas must be repaired prior to proceeding with the resinous installation. For proper patching and repairing, use CF-615 and/or E1000 with graded aggregate.  Remove existing paint and loose concrete by rough sanding, sandblasting, high pressure water cleaning, shot blasting or grinding. In some cases where plant conditions allow, a  stripper may be used to remove excessive build-up of paints or sealers.


E1500HN must be applied over the PC-155 or PC-1703 while they have a slight tack. PC-1500 can be applied as an aggregate filled epoxy mortar by hand trowel. Apply pressure to compact material to a dense, monolithic topping. E1500HN can be squeegeed for self-leveling, thin film coating and reinforced floors. E1500N is also used as a 16-40 mil coating. A porcupine roller is recommended to break any air bubbles in the E1500N when rolling.

For exterior use or higher film build, seed dry E1500N with fine aggregate. For vertical coating requirements, recommend the E555VN Novalac Epoxy.


The aggregate filled epoxy mortar has an open time of approximately 15-20 minutes at 75°F. Immediately after mixing a batch it should be placed and spread onto the surface to be protected. Highly filled, will be ready for foot traffic in 4-5 hours. Self-leveling slurries will be ready for foot traffic in 6-8 hours and fork lift traffic in 24 – 48 hours. In aggressive areas, a 16-40 mil dry sealer coat of E1500HN is recommended to top coat mortars and self leveling slurries. A 16-40 mil coat will be ready for foot traffic in 8-12 hours.



E1500HN Novolac Epoxy is Flammable.  Keep away from all sources of ignition during mixing, application and cure.  The Hardener and Base can cause eye and skin burns as well as allergic reactions.  Use goggles, fresh air masks or NIOSH approved respirators, protective skin cream and protective clothing.
