Application introduction
CU/CT is an kind of efficient cyclic phosphonate flame retardant. It contains high phosphorus
with an excellent water solubility. It could be applied in the fabric for inner vestee used in bulidings,
curtainings and cars and special workwear. It is particularly suitable for the treatment of polyester
fabrics , T/C blends and PU coating to impart the fabric to have the flame-stop effect. The effect of
the fabric after treatment will be long-lasting and durable to wash with wide-range application!
