Nukote Chemshield TS

Nukote Chemshield TS is a plural component system composed of ceramics in a polymeric binder, providing excellent performance in corrosive, chemical and abrasive environments, at ambient or elevated temperatures. This product is designed for industrial use at elevated temperatures and will maintain its physical properties under continued exposure at high constant temperature both in exposed as well as immersed conditions. Nukote Chemshield TS is resistant to all petroleum distillates, most solvents, dilute acids, dilute alkalis, Sulphur fumes, acid fumes, designed to resist water, aqueous solutions and hydrocarbons up to a temperature of 350 °F (175 °C) in immersion. Chemshield TS is also suitable in cryogenic applications as well as in applications requiring to handle thermal cycling.

Twelve to eighteen months in factory delivered, unopened drums. Store on pallets and keep away from extreme heat, freezing, and moisture. The use of drum heaters is encouraged to reduce material viscosity at low temperatures.


Nukote Chemshield TS might not be diluted under any circumstance. Mixing ratio for Chemshield TS is 4:1 by volume. Add 4 parts of Base (A) to 1 part of Hardener (B). Mix gently the Side A (base) using a heavy duty slow speed drill fitted with a mixing paddle or commercially available paint mixers. Add side B (hardener) to side A and mix it thoroughly until a streak free homogeneous color is obtained. Chemshield TS is ready to be applied and may add 2 % thinner (consult NCSI) when utilizing airless spray equipment or in cold climates .Mix only the quantity that can be used during the pot life.

Discard material when the mixed material start gelling and do not try to re-use by adding thinner. Mixing this product manually by hand is not recommended. When environment temperature is below50 °F (10°C), the product can be indirectly heated to 70 to 80 °F (20-25 °C). This will make mixing easier and accelerate curing and may have effect on Pot life.



The surface of a concrete subfloor should be dry, smooth, structurally sound and free of depression, scale, or foreign deposits of any kind. Remove all curing compounds. Abrasive blast, sweep blast or water blast to remove all latent material and expose voids. Use a good quality epoxy filler or mortar for void and spall filling, skim coat or repairs. Prime, fill imperfections in the substrate surface to limit out-gassing. All concrete substrates, on or below grade level should be tested for moisture content. On-grade or below-grade concrete floors or slabs should have a moisture barrier installed to protect from ground moisture. The surface preparation of concrete should meet and conform to Joint NACE 6/SSPC-SP 13 standards and achieve a concrete surface profile of CSP 3 to CSP 6 as per ICRI Guideline No.03732 for optimum performance.


All surfaces should be clean and free from contamination. The surface should be assessed and treated in accordance with ISO 8504, Abrasive blast the surface to minimum NACE-1/SSPC SP-5/Sa3, as per ISO 8501-1, for a visual assessment of surface cleanliness with an anchor profile of 3 to 4 mils (75 -100 microns). Soluble salts must be removed to an acceptable levels. Refer to NCSI surface preparation manual for detailed procedures for different types of substrates.


This product can be applied by dedicated airless spray equipment, brush, roller or trowels depending on the volume and project size. The Nukote recommended spray equipment is which will completely avoid material loss due to exothermic heat, Gelling and pot life. An airless pump 45:1 or higher is recommended. Trowel grade material is also available for a higher DFT metal repair and rebuilds application. Chemshield is applied over properly repaired substrates in the method most suitable for the application type. Complete application details are provided in SDS. (Supplementary data sheet)


Cured product may be disposed of without restriction. Uncured activator and resin portions should be mixed together and disposed of in accordance with local regulations. Containers should be disposed of according to local environmental laws and ordinances.

This product contains Amine and curatives


Each Nukote product formulation has varying levels of resistance to specific chemicals. Please review the chemical immersion test data included in the Nukote Test Book for general resistance to specific chemicals at specific concentration levels. Chemical concentrations are complex and when combined with temperatures above ambient levels this complexity increases exponentially. Contact Nukote Technical Personnel for specific recommendations for chemical resistance prior to specifying these products in this application type. Consult with NCSI for more details on product and chemical resistance. The following chart is the results of Polyurea immersed in chemicals and tested as per modified ASTM D 3912.
