Abstract: Fire retardation and wood preservation compositions having inorganic salts encapsulated by a water-based acrylic resin solution. The salts are carried by water into the wood or cellulose product to be treated. After the water evaporates, the inorganic salts are retained in the treated wood and not leached from or washed out of the wood product. The component compounds of the compositions are mixed in specific sequences to avoid coagulation of the mixture.
