duoMatrix®–C is new polymer additive that enhances the physical and performance properties of cementitious materials such as portland cements and mortars. duoMatrix®–C (Matrix®-C for short) eliminates the need for the usual 7-day post cure. It drastically reduces water and salt absorption and fills in micro cracks to minimize crack propagation. Other performance characteristics include greatly enhanced freeze/thaw, ultra-violet, and chemical resistance. Higher flexural strength reduces brittleness. Matrix®-G is available to enhance the performance of alpha-gypsums. Matrix®-C is easy to use and can be introduced to any aggregate mix. It is usually cast solid or mixed with chopped fiber and sprayed. Matrix®-C can be pigmented and improves color uniformity. Matrix®-C will improve processing of GFRC, making architectural elements and concrete castings (ornamental, etc.) more durable.

Parts By Weight Important: Components must be mixed in proper sequence. A power mixer should be used to mix all components.
