What Is Thread Coating Liquid
According to Precote.com, liquid thread coating is the application of a sealant, lubricant or anti-corrosion chemical to the threads of screws, nuts and bolts. Liquid thread coatings are used by automotive manufacturers, the airline industry, railway companies, shipyards and nearly every manufacturing industry. Liquid thread coatings can be applied during the manufacturing process or after-market to the threads of screws, nuts and bolts.
Liquid Nylon
Liquid nylon provides a number of benefits when applied to part threads and works well on both iron and non-iron metal threads, such as steel, aluminum, brass and stainless steel threads. A thin layer of liquid nylon protects threads from wear, friction and corrosive elements and inhibits electrical conductivity. The nylon remains intact in both high heat and freezing temperatures.
Wax
Wax-based liquid thread coatings serve primarily as a thread lubricant. Wax-based liquid coatings are applied to nut, bolt and screw threads to make assembly smoother and to avoid cross-threading or sticking threads. The liquid wax is sprayed on the part or the part is dipped in the wax by a machine, or the wax can be applied by hand. New threaded parts may be coated with liquid wax lubricant at the end of the manufacturing process.
Teflon
Liquid Teflon is often applied to threaded parts as a sealant and to help reduce wear caused by friction. Liquid Teflon is typically used on screws, nuts and bolts that are subjected to vibration, such as those used in refrigeration units and manufacturing environments. Liquid Teflon thread lubrication applications may contain other chemicals, such as polytetrafluoroethylene that increase the efficiency of Teflon lubrication. Teflon is used on metal, plastic and fiberglass parts.
Fluoro-Carbon Coating
Liquid fluoro-carbon thread coatings prevent threads from damage during assembly of parts by lubricating the threads. Fluoro-carbon thread coating is often used on part threads if the final product will be painted before or after assembly. Once dry, the fluoro-carbon coating resists paint. Fluoro-carbon coatings also resist electroplated paints and primers.
