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 Cellu-Treat® brand.
QNAP can be used as a stand-alone or as a dual treatment with Cellu-Treat. Cellu-Treat 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.
QNAP is an 8% oil-borne copper naphthenate solution that is an EPA-registered, non-restricted/general use preservative also standardized for use by the AWPA (P36).
Cellu-Treat is a Disodium Octaborate Tetrahydrate (DOT) wood preservative that is available in a 98% water soluble powder and a 50% liquid concentrate.
The BTX system allows the addition of Cellu-Treat borate to the heartwood of green bridge ties so railroads can take advantage of all the benefits of dual treatment in the Bridge Tie Program
