If you’re looking for green solutions for railroad crossties, switch ties, bridge timbers and pilings, Nisus Corporation has the answers. We manufacture copper naphthenate under the QNAP® brand and a Disodium Octaborate Tetrahydrate (DOT) borate wood preservative under the Cellutreat® brand.
QNAP can be used as a stand-alone or as a dual treatment with Cellutreat. Cellutreat can be used as a dual treatment with QNAP or creosote. Both are EPA-registered “general use” preservatives and standardized by the American Wood Protection Association (AWPA). Let us show you how these products can create a greener tie and timber program for your company.
