DuraQ-CuNap is an 8% oil-borne copper naphthenate solution that is an EPA-registered, non-restricted use/general use preservative also adopted as standard for use by the AWPA (P36). The product is created from recycled copper and by-products of oil refining – making it green from the start.
DURAQ-CUNAP has performance equal to all other oil-borne/oil type preservatives. Use of DURAQ-CUNAP requires no special equipment. Wood treated with DURAQ-CUNAP is non-hazardous waste, which allows for recycling or energy recovery.
