Application fields:
SPT is mainly used as antiseptic and mould proofing for daily chemical engineering expenses (shampoo and hair care products), building coating, mastic, aquaseal, pesticide, textile products, lusterwares, processing liquid of metal. It also can used to prepare antiseptics, washing chemicals and medical care of broad-spectrum eumycet dermatology. What's more, it is effective bactericide for fruit trees, peanuts, wheat and vegetables and antiseptics for silkworm use. Thus, SPT and other products of the same kinds are widely used in concerned fields due to its highly effective, broad-spectrum and harmfulless properties.
