Magnesium cement has low alkaline (PH 8-9). Large chloride content, large modifier content, fast consolidation characteristics. Magnesium cement needs foaming agent adaptive to low alkalinity, chloride-resistant, not effected by modifier, as well as large output. Magnesium Oxide foaming agent is developed to meet magnesium cement characteristics. Water Diluent: 30 times Output: 1L Magnesium Oxide foaming agent generates 800-1000L foam. PH: 8-9 Density: 1.05 Color: light brownish liquid Packing: 200kg/barrel, 1000kg/barrel Storage: 12 months. Cool place, no direct sun Application: fireproof door, door fill-in, light weight Magnesium Oxide wall board.
