Usage
1. Tetramethylolsulfate is a green environmentally friendly quaternary phosphocide fungicide. Its product has good water solubility, low freezing point and stable chemical properties. It is a new type, high efficiency and broad spectrum. Low toxicity, low dose, low foaming, environmentally friendly fungicide.
2. Tetramethylolsulfate is also a permanent flame retardant for pure cotton and polyester/cotton fabrics. Because of its chemical structure, it has an active methylol group, and its reaction performance is active. It can form high polymers with many substances such as amines and phenols.
