Usage: Tetrakis[hydroxymethyl] phosphonium sulfate is a biocide effective against micropest in industrial cooling systems, oil field operations, and paper-making industry. The advantage is it will soon degrade to a nontoxic substance immediately after use. Also it can be applied to fabric coating, obviously in improving flame retarding property.
Storage: Store in cool, well-ventilated areas. Keep away from ignition sources, heat and flame. Store in tightly closed containers. Incompatibilities: oxidants and food.
