SolidCor 237 Temperature Resistant Urethane Cement Slurry

Dymond SolidCor 237™ is a heavy-duty, bio-based urethane cement flooring system designed for demanding commercial and industrial environments. Its pourable slurry formulation delivers outstanding wear performance together with resistance to thermal shock, impact, abrasion and chemical exposure. SolidCor 237 can withstand higher heat exposure than typical unmodified urethanes and is particularly well suited to hot washdown areas. Recommended applications include commercial kitchens, food preparation areas, food and beverage facilities, restrooms and locker rooms. The premeasured multi-component system is spread using a cam rake and backrolled with a spike roller. Aggregate or decorative flakes can then be broadcast into the wet slurry to create a durable, seamless and hygienic floor with no grout lines. Why Choose SolidCor 237? Good thermal shock resistance Heat resistance up to 200°F Outstanding wear performance Resistance to impact and abrasion Resistance to a range of chemical exposures Suitable for hot washdown areas Seamless, hygienic finish with no grout lines Low-odor, water-based formulation Fast installation and fast cure No primer normally required on properly prepared concrete Suitable for aggregate and decorative flake broadcast systems Optional topcoat depending on the required finish and system design Recommended Applications Commercial kitchens Restaurant kitchens Food preparation areas Food processing facilities Food and beverage facilities Beverage production areas Hot washdown areas Restrooms Locker rooms Demanding commercial and industrial floors Built for Demanding Environments SolidCor 237 is formulated for floors exposed to demanding operating conditions. Compared with typical unmodified urethanes, it can withstand higher heat exposure and provides good thermal shock capabilities, making it a suitable choice for hot washdown environments. The system also withstands moderate impact, abrasion and chemical exposure. Its seamless construction eliminates grout lines where dirt and contaminants can collect, helping to create a durable and hygienic surface for commercial kitchens and food and beverage facilities. Chemical Resistance SolidCor 237 has been tested against a range of food-related substances and industrial chemicals. Spot testing showed no physical damage from mustard, ketchup, lactic acid, vinegar or lemon juice. The product also passed 24-hour immersion testing with 10% acetic acid, 30% nitric acid, 50% sodium hydroxide, 30% sulfuric acid and xylene. Chemical mixtures and exposure to chemicals at elevated temperatures should always be evaluated before installation. Installation SolidCor 237 is normally installed directly onto properly prepared concrete without a primer. If concrete outgassing occurs during application, installation should be stopped and a suitable primer applied before continuing. Immediately after mixing, the pourable slurry is spread to the required thickness using a cam rake or other suitable equipment. It is then backrolled with a spike roller to settle the aggregate and reduce rake lines, followed by a loop or texture roller before broadcasting. Aggregate or decorative flakes can be broadcast to rejection into the wet slurry. Once cured, the excess broadcast material is removed and the surface can be scraped before applying an optional topcoat to lock in the aggregate.

Yes. SolidCor 237 is recommended for commercial kitchens, food preparation areas and food and beverage facilities where a durable, seamless and shock-resistant floor is required. How do I mix SolidCor 237 urethane cement slurry? SolidCor 237 is supplied in premeasured kits and the complete kit should be mixed as supplied. Do not divide or modify the components. Pour Part A into a clean five-gallon mixing pail. When using the separate dry pigment, add the complete pigment bag to Part A and mix for approximately 15 seconds using a low-speed drill and Jiffy-style mixing paddle. Add Part B and mix for a further 15 seconds. Gradually add the complete bag of blended aggregate and continue mixing for approximately two minutes, or until all aggregate particles are thoroughly wetted and the mixture is uniform. Use slow-speed mixing equipment to avoid introducing excessive air. Transfer the mixed material into a second clean pail and remix before application. Apply the product immediately after mixing, as the working time is approximately 15 minutes at 77°F. How much area does one kit cover? One standard SolidCor 237 kit typically covers approximately 37–46 square feet at 1/8-inch thickness. Actual coverage will vary depending on the concrete profile, application thickness, surface condition and complete system configuration. Can SolidCor 237 handle heavy traffic? SolidCor 237 is designed for demanding, high-wear commercial and industrial environments exposed to impact, abrasion and heavy use. It has a typical compressive strength of 8,400 psi, a Shore D hardness of approximately 80 and 100% concrete failure during bond-strength testing. At 77°F, allow approximately 12 hours before light foot traffic, 24 hours before heavy foot traffic and seven days for full cure. Colder temperatures will increase the required cure time. What surface preparation is required? The concrete must be structurally sound, dry and free from dirt, oil, laitance, coatings and other contaminants. Fine brush blasting or shot blasting is the preferred preparation method. The finished concrete should have an ICRI CSP 3–5 surface profile. Repair cracks, bug holes and other concrete imperfections before installation, and grind down raised projections. Do not apply SolidCor 237 over cracked or unsound concrete that has not been properly repaired. Anchoring keyways measuring at least 5/16 inch wide by 5/16 inch deep must be cut at terminations, joints, columns, doorways and drains to help prevent lifting and delamination. Does SolidCor 237 require a primer? A primer is not normally required when SolidCor 237 is installed over properly prepared concrete. If concrete outgassing occurs, stop the installation and apply a suitable primer before continuing. At what thickness should SolidCor 237 be installed? Typical finished installations range from approximately 1/8 to 3/16 inch, depending on the condition of the concrete, the broadcast material and the selected topcoat system. SolidCor 237 should not be feather-edged. Can aggregate or decorative flakes be used? Yes. Aggregate or decorative flakes can be broadcast into the wet slurry. The surface should be broadcast until no wet areas remain. Once cured, remove the excess material and scrape the floor as required before applying an optional topcoat. Does SolidCor 237 require a topcoat? A topcoat is optional and depends on the required finish and complete flooring system. When aggregate or decorative flakes are broadcast into the slurry, a suitable topcoat can be applied to lock the broadcast material into the surface. How much heat can SolidCor 237 withstand? The published heat resistance is up to 200°F. SolidCor 237 can withstand higher heat exposure than typical unmodified urethanes and has good thermal shock capabilities. However, high heat may discolor the surface, and chemical exposure at elevated temperatures should be evaluated before installation. Important Installation Considerations Do not install over wet, cracked or unsound concrete. New concrete must be cured for at least 15 days before application. The substrate temperature must remain at least 5°F above the dew point. Apply between 45°F and 85°F with relative humidity below 85%. Moisture vapor transmission must not exceed 12 lb per 1,000 sq. ft. over 24 hours. The product is not UV or color stable and may discolor under high heat or certain lighting conditions. Floors should be sloped toward drains to prevent standing water and reduce slipping hazards. Always install a suitable test area to confirm performance, appearance and compatibility before completing the entire project.
