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. \u003cstrong\u003eMatrix™-G\u003c\/strong\u003e is available to enhance the performance of alpha-gypsums. \u003c\/p\u003e\r\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shoplightspeed.com\/shops\/606431\/files\/52202150\/duomatrixcmixratio.png\" alt=\"\" width=\"861\" height=\"235\"\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shoplightspeed.com\/shops\/606431\/files\/52202151\/duomatrixcspecs.png\" alt=\"\" width=\"410\" height=\"628\"\u003e\u003c\/p\u003e\r\n\u003cp\u003eFeatures\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eEasy to use and can be introduced to any aggregate mix.

These products have a limited shelf life and should be used as soon as possible. Colder temperatures will slow the working\/cure time, while warmer temperatures will reduce working times. Individual components should be stored in a dry environment at room temperature. Humid conditions will cause plaster and resin to lose effectiveness. \u003cstrong\u003eDo not latex freeze.\u003c\/strong\u003e Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.\u003c\/p\u003e\r\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMold Preparation\u003c\/strong\u003e -\u003c\/em\u003e When solid casting \u003cstrong\u003eMatrix™-C\u003c\/strong\u003e into a rubber mold, rinse the mold with solution with any standard concrete release agent prior to each casting.

Colder temperatures will slow the curing process. Do not cure in temperatures below 32°F \/ 0°C. Warmer temperatures will accelerate the curing process. If curing at temperatures above 105°F \/ 32°C, castings should be covered to prevent pre-mature evaporation. This could result in surface shrinkage and cracking.\u003c\/p\u003e\r\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAccelerating Or Slowing Matrix™-C\u003c\/strong\u003e\u003c\/em\u003e - Accelerating or slowing the cure of Matrix™-C may be achieved with conventional ad mixtures (such as Daraccel accelerator or Daratard 17 retarder from WR Grace.
