SolidCor 230 Novolac Chemical Resistant Epoxy

SolidCor 230 Novolac Chemical Resistant Epoxy

Dymond SolidCor 230 is a two-component, high-solids novolac epoxy coating engineered for severe chemical-service environments where acids, caustics, solvents and aggressive industrial chemicals may be present. Applied as a high-build finish coat, it creates a dense, durable and highly chemical-resistant surface over properly prepared and primed concrete, masonry or brick.

SolidCor 230 is designed for demanding industrial areas where ordinary epoxy coatings may not provide sufficient resistance. Its hard, abrasion-resistant finish makes it suitable for traffic areas, chemical troughs, curbs, tanks, containment zones and spill-prone processing environments.

Chemical Resistance

SolidCor 230 is designed for exposure to a wide range of aggressive chemicals. Published testing includes long-term immersion resistance to 10% and 50% sodium hydroxide and 10% sulfuric acid, together with strong resistance to hydrochloric acid, acetic acid, xylene, solvents and other industrial chemicals.

Chemical performance depends on the chemical concentration, temperature, exposure duration, cleaning procedures and the complete flooring system. Confirm suitability for critical applications before installation.

System Guidance

Dymond BondMaxx 140 Novolac Primer is the recommended primer beneath SolidCor 230. The primer helps seal porous substrates, improve adhesion and reduce outgassing before the high-build novolac finish is applied.

SolidCor 230 is intended to serve as the final chemical-resistant coating, and an additional topcoat is not normally recommended.

Application Overview

The substrate must be clean, dry, sound and mechanically prepared. Remove all dirt, oil, laitance, coatings and other contaminants that could interfere with adhesion. Shot blasting is generally the preferred preparation method for high-build industrial systems.

Prime the prepared substrate with BondMaxx 140 and allow it to reach the correct recoat stage. Combine Part A and Part B at the specified ratio and mix thoroughly using slow-speed mixing equipment until the material is uniform and streak-free. Transfer the mixed material into a clean pail and remix before application.

Apply SolidCor 230 by serrated squeegee, roller or other suitable equipment at the recommended 16 to 18 mil thickness. Maintain a wet edge and apply consistently to avoid uneven color or texture. Use an air-release roller where required to help remove entrapped air.

Important: Apply only when the substrate temperature is at least 5°F above the dew point. New concrete must be properly cured before coating. SolidCor 230 is not UV color stable and may discolor in direct sunlight or under some lighting conditions. Refer to the Technical Data Sheet and Safety Data Sheet before use.

1) PRODUCT STORAGE: Store product in an area as to bring the material to normal room temperature before using.
Continuous storage should be between 60 and 90 degrees F. Low temperatures or great temperature fluctuations may cause product crystallization.

2) SURFACE PREPARATION: The most suitable surface preparation would be a fine brush blast (shot blast) to remove
all laitance and provide a suitable profile. All dirt, foreign contaminants, oil and laitance must be removed to assure a
trouble free bond to the substrate. A test sh ould be made to determine that the concrete is dry; this can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

3) PRODUCT MIXING: This product has a mix ratio of 10.15# part A to 4.2# part B for standard colors. Standard packages are in pre -measured kits and should be mixed as supplied in the kit. We highly recomm end that the kits not be broken down unless suitable weighing equipment is available. After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. After mixing, transfer the mixed material to another pail (the transfer pail) and again remix. The material in the transfer pail is now ready to be applied on the primed substrate. Improper mixing may result in product failure.

4) PRIMING: A suitable primer should be used before applying this product. See the front side of this technical data for primer information. If a primer is not used, more porous substrates may cause outgassing and possible surface defects.

5) PRODUCT APPLICATION: The mixed material material can be applied by brush or roller. However, the material can also be applied by a suitable serrated squeegee and then back rolled as long as the appropr iate thickness recommendations are maintained. Maintain temperatures and relative humidity within the recommended ranges during the application and curing process. If concrete conditions or over aggressive mixing causes air entrapment, then an air release roller tool should be used prior to the coating tacking off to remove the air entrapped in the coating.

6) RECOAT OR TOPCOATING: If you opt to recoat or topcoat this product, you must first be sure that the coating has tacked off before recoating. However, all previous coats should be deglossed to insure a trouble free bond prior to application of recoats or topcoats. Always remember that colder temperatures will require more cure time for the product before recoating or topcoating can commence. Before recoating or topcoating, check the coating to insure no epoxy blushes were developed (a whitish, greasy film, or deglossing.) If a blush is present, it must be removed prior to topcoating or recoating. Multiple coats of this product are acceptable and can be used to achieve greater chemical resistance and build.

7) CLEANUP: Use xylol

8) FLOOR CLEANING: Caution! Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.

9) RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.

That’s why we back every eligible Dymond kit with our Lifetime Promise: if your floor fails due to a verified product defect, we’ll replace the material or issue a credit toward your next job. This warranty applies to complete Dymond systems (primer, base coat, and topcoat) when installed on indoor concrete surfaces and applied according to Dymond’s preparation and application guidelines. Covered issues include delamination caused by faulty resin blends, curing failure due to batch defects, and contamination introduced during manufacturing or packaging. To qualify, the product must be within shelf life, used under proper storage conditions, and installed using only Dymond components.

This warranty does not extend to issues arising from improper surface preparation, substrate contamination, excessive moisture vapor, impact or abuse, substrate movement, or UV discoloration of white/light epoxies. Installations over wood, tile, or outdoor surfaces are excluded unless specifically approved. Cosmetic issues such as texture variation, microbubbling, or minor tint shift are not covered. Warranty coverage is limited to the original purchaser and is non-transferable. Claims must be submitted with photographic evidence of each install stage and full batch documentation. Dymond reserves the right to determine whether the cause of failure falls within warranty scope.

This Promise applies to most DIY and light commercial indoor projects. Larger commercial and industrial installations may be eligible for custom coverage — contact us for terms.

Can This Be Installed Over My Existing Floor?

Yes, in many cases, but the floor underneath has to be clean, solid, and mechanically prepared. The coating can only bond as well as the surface it is applied to.

Every floor is different. When coating over anything other than properly prepared concrete, we strongly recommend applying a small test area first.

Bare Concrete

Best Surface

This system is designed to bond to properly prepared concrete. The concrete must be clean, dry, sound, and mechanically ground or shot blasted.

Existing Epoxy

Good With Prep

This system can be installed over an existing epoxy coating if the old coating is firmly bonded, clean, sound, and fully deglossed.

Tile

Conditional / Test First

Can be installed when tile is firmly bonded, clean, degreased, abraded, and tested first. Installation is done at your own risk.

VCT Tile

Conditional / Test First

Many customers successfully coat over VCT, but the bond depends on tile, adhesive, waxes, moisture, and movement. Installation is at your own risk.

Wood

Conditional / Scratch Coat

Requires a scratch coat first. Wood installations are done at your own risk. Always test first.

Required Surface Prep

For a strong bond, the surface must be mechanically prepared. Cleaning alone is not enough.

1

Grind or Shot Blast

The floor must be mechanically ground or shot blasted to create a surface profile the coating can grip.

2

Remove Contamination

Oil, grease, wax, soap residue, dust, old adhesive, sealers, and loose material must be removed before coating.

3

Repair Cracks & Defects

Cracks, holes, divots, and damaged areas should be filled before coating for a stronger, smoother finish.

4

Test First When Unsure

For tile, VCT, wood, unknown coatings, sealed floors, or questionable surfaces, apply a small test area.

Installation Questions We Get Every Week

Click any question to expand
? Does the floor need to be ground?

Yes. For a strong bond, the coating needs a clean, mechanically prepared surface profile.

? What does delamination mean?

Delamination is when the coating separates, peels, bubbles, or lifts from the floor underneath.

? Can this be installed over an existing epoxy?

Often yes, if the existing coating is fully bonded, clean, sound, abraded, and tested first.

? Can this be installed over VCT tile?

Sometimes, but the installation depends on the tile, adhesive, waxes, movement, and moisture. Test first.

? Can this be installed over wood?

Wood is conditional and normally needs a scratch coat. Always test first.

? Can this be installed over tile?

Tile can be conditional. It must be firmly bonded, cleaned, abraded, and tested before a full installation.

OK

Still Not Sure? Test Before You Coat.

Every floor is different. If you are coating over tile, VCT, wood, an unknown coating, sealed concrete, or a questionable surface, apply a small test area first before installing the full system.

The coating can only perform as well as the surface underneath it.
