8 Oz. Jar Pre-Tinning Paste Flux

RectorSeal 14115 Nokorode™ Pre-Tinning Solder Flux – 8 oz Professional Grade – Technical Information

RectorSeal Nokorode™ 14115 Pre-Tinning Paste Flux is a professional-grade soldering compound engineered to clean, pre-tin, and flux metal joints in one operation. Formulated with fine 95/5 tin-antimony solder powder and a proprietary heat-activated cleaning agent, this compound enhances wetting and flow characteristics across copper, brass, nickel, and other ferrous and non-ferrous metals. The integrated solder content provides a visual heat indicator during application and ensures consistent joint pre-tinning prior to reaching soldering temperature. Ideal for heavy-duty plumbing, HVAC, and mechanical joining applications, Nokorode™ Pre-Tinning Flux promotes uniform heat transfer, efficient solder flow, and durable, corrosion-resistant joints in professional installations.
