An addition to the StrataShield line of resinous floor and wall products, Series 256 ExcellaThane from Tnemec Co. Inc. is a modified aliphatic polyaspartic that provides a return-to-service time of three hours for light traffic and six hours for full-service and low-temperature cure capabilities. The coating can be used as a thin film or for building aggregate, quartz or decorative flake-filled floor covering.

As a 100% solids polyaspartic, Series 256 is low in VOCs and exhibits low odor, allowing use of the coating near occupied spaces. This characteristic makes Series 256 a viable alternative to methyl methacrylate floor coating products that exhibit a distinctively strong odor.
