Chem-Thane 509 Satin V.2018
- 1.0 Gallon Unit
- 4 Gallon Unit (special order with extra lead time).
- Superior UV resistance
- Easy 3:1 mix ratio
- Highly abrasion resistant
- Remains flexible
- High coverage rate
- Chemically resistant to many non-solvents
CHEM-THANE 509 is a 2-component, 50% solids water-clear, polyester aliphatic polyurethane. This high-performance CRU produces a durable satin finish, is non-chalking and has superior UV resistance. CHEM-THANE 509 provides superior protection from many chemicals and has excellent abrasion resistance.
CHEM-THANE 509 is an ideal protective satin finish coating for applications to ROCK-TRED floor or wall systems. It is an excellent high performance finish coat where UV resistance is important and where some odor can be tolerated.
CHEM-THANE 509 should be applied at an approximate coverage rate of 300 - 400 sq. ft. / gal.
CHEM-THANE 509 is manufactured and normally stocked in 1.0 gallon units only. Four Gallon units are available with additional lead time and in minimum order quantities. This product is not offered in solid colors.

Limitations & For Best Results
- Do not thin this product.
- Do not apply when Humidity exceeds 85%.
- Do not allow to puddle during application or during cure. Allow each coat to dry completely prior to re-coat.
- Allow previous coatings of other polymer products to dry completely prior to application of CHEM-THANE 509.
- When re-coating, always apply the next coat between 12 - 24 hours of completing the previous coat.
- Allow for proper ventilation with indirect air flow and keep away from ignition sources. Poor ventilation can lead to solvent entrapment which can inhibit product curing and cause yellowing.
- Do not apply this product heavier / thicker than the recommended spread rate / mil thickness. Product should be applied in thin coats not exceeding 5 mils WFT.
- Do not apply directly to bare concrete.
- This product has broad spectrum chemical resistance, but like all CRU, is not highly resistant to solvents.
Apply using brush and ¼” mohair roller or lamb’s wool applicator. ROCK-TRED product test data is based on environmental temperatures of 75° F. Viscosity and working time are always affected by temperatures above or below that mark. When applying product – always consider the ambient, surface, and product temperature at the time and place of installation.
Color and Textures
CHEM-THANE 509 Satin is stocked in 1.0 gallon units only. Four gallon kits require 7-day lead time AND a 30-gallon minimum order. Solid colors are not available.
Most ROCK-TRED products are available in a wide range of textures using an appropriate broadcast aggregate, but aggregate larger than 240 mesh may not remain in CHEMTHANE 509 under traffic. Approximately 1.42 pounds of ROCK-TRED’s 240 grit Aluminum Oxide powder may be added into 1 gallon of CHEM-THANE 509 at the time of mixing to increase abrasion resistance and the cured coating’s coefficient of friction. Adding AO powder will leave a superfine grain texture in the finish and will reduce light reflectivity. Repeated stirring the product during application to avoid the AO settling and then careful and even application is needed to avoid roller marks when AO powder has been added.
Always refer to ROCK-TRED’s chemical resistance chart for specific information on each product / system or contact ROCK-TRED directly.
DO NOT allow ROCK-TRED products to freeze. All ROCK-TRED products should be properly stored above the floor on pallets or shelves, and in an area that has a constant minimum temperature of 50°F.
Always apply ROCK-TRED products to a clean / sound substrate that is free of laitance, grease, oils, debris and curing compounds. Make certain that concrete is property dried and prepared before applying ROCK-TRED materials. Concrete substrates should be treated with the Rock-Block System when moisture testing per ASTM F2170 shows results over 80% RH. Whenever possible, remove existing coatings and/or flooring systems completely; if complete removal is not possible test to determine adhesion to the existing material. Mechanical preparation by means of shot-blasting or diamond grinding to a ICRI CSP 2/3/5 is the recommended preparation method (see ICRI Guideline No. 03732 for more information). 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.
Application tools and equipment can be cleaned with soap and water immediately after use or with solvent once the product has begun to cure.
Product containers will contain product residue and must be disposed of properly. Label warnings must be observed at all times. All containers must be disposed in accordance with federal, state, and local regulations.
Always read and acquaint yourself with ROCK-TRED’s Product Data Sheet, SDS [safety data sheet], and product labels for each individual product prior to mixing and prior to use. For further assistance, product questions, additional information and/or unexpected or unusual installation conditions – contact your Area Sales Representative or ROCK-TRED directly for recommendations. Kit components are pre-measured for optimal performance. Catalyzation errors due to incorrect mixing in the field voids product warranty.
