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. Key Benefits High-performance novolac epoxy for severe chemical exposure Resists acids, caustics, solvents and industrial chemicals High-solids formulation with low VOC content High-build 16 to 18 mil application Excellent hardness and abrasion resistance Strong adhesion to properly prepared and primed substrates Suitable for horizontal and vertical surfaces Designed for traffic areas, containment zones, curbs and chemical troughs Available in light gray, medium gray and tile red Recommended Uses Chemical processing plants Secondary containment areas Battery manufacturing and charging rooms Wastewater treatment facilities Pickling and metal-plating areas Petroleum and refinery facilities Pulp and paper mills Food and beverage processing chemical areas Chemical troughs, curbs and spill zones Tanks and equipment containment bases Concrete, cement masonry and brick surfaces Technical Data Resin type: Two-component colored novolac epoxy Solids by weight: 96%, plus or minus 1% Solids by volume: 94%, plus or minus 1% VOC: Less than 44 g/L Standard colors: Light gray, medium gray and tile red Finish: Gloss, greater than 40 at 60 degrees Recommended film thickness: 16 to 18 mils Coverage: Approximately 90 to 100 sq. ft. per gallon Mix ratio by weight: 10.15 lb Part A to 4.2 lb Part B Approximate mix ratio by volume: 2 parts Part A to 1 part Part B Packaging: 3 gallon and 15 gallon kits Shelf life: 1 year in unopened containers Hardness: Shore D 88 Compressive strength: 9,900 psi Tensile strength: 6,680 psi Flexural strength: 9,610 psi Adhesion: 425 psi with concrete failure and no delamination Abrasion resistance: 20 mg loss, CS-17 wheel, 1,000 g load, 500 cycles Heat deflection temperature: 115.5°F Cure Schedule at 70°F Pot life: 25 to 35 minutes for a 1.5 gallon mixed volume Tack-free: 5 to 7 hours Recoat: 5 to 10 hours Light foot traffic: 10 to 18 hours Full cure and heavy traffic: 2 to 7 days 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.
