precote® products offer optimal solutions for thread locking and sealing, as well as controlled joint assembly and disassembly. These specially developed threadlockers and sealers are designed for application onto the threaded area of fasteners. Our threadlockers are based on our unique dual micro-encapsulated adhesives, enabling us to offer many advantages over conventional adhesives.
The pre-applied adhesive remains inactive until the coated fastener is assembled onto the mating part. During the assembly the micro capsules are ruptured, initiating the polymerization process, curing the assembly quickly at room temperature, providing reliable locking and immediate sealing properties to the assembly.
precote® 80 is a high strength and high temperature resistant thread locking and sealing coating designed to be used on all types of external or internal threaded fasteners. When it comes to pre-applied adhesives, there is none stronger than precote® 80.
precote® 85 is a high strength and high temperature resistant thread locking and sealing coating designed to be used on all types of threaded fasteners. precote® 85 features a very low coefficient of friction upon assembly providing excellent controlled torque vs tension features. This exclusive turquoise colored precote® 85 can be applied to either internal or external threaded fasteners.
precote® 30 is a medium strength thread locking and sealing coating designed to be used on all types of external or internal threaded fasteners. It is especially recommended for fasteners with thread sizes equal or larger than M16 in order to provide easier disassembly. It’s low Coefficient of Friction provides lower installation torque values and it is ideal for engine plug sealing applications.
precote® 5 provides immediate sealing for assembly components such as screws, studs, plugs, nuts and pipe threads. It seals against gases, petroleum-based products, brake fluid and other liquids. Non-reactive and water-based, precote® 5 provides immediate sealing for all types of threaded fasteners including under the head applications.
precote® 15 provides immediate sealing for higher temperature assembly components such as screws, studs, plugs, nuts and pipe threads. It seals against gases, petroleum based products, brake fluid and other liquids. Its excellent adhesion properties are ideal for sealing applications on brass, aluminum, copper and stainless-steel fasteners.
precote® 200 is a resilient, under-the-head sealant which can be used to seal the mating surfaces of screws and plugs eliminating the need for O-rings and gaskets. precote® 200 provides excellent adhesion to the mating surfaces and consistent sealing performance immediately after assembly.
precote® Top 100 is a film-forming surface coating base with temporary corrosion protection. precote® Top 100 reduces friction under the head and on threaded areas. It is applied over precote micro-encapsulated adhesives without significant loss of locking ability.
precote® Top 300 Thread Lubricant is a film-forming synthetic wax pre-applied onto threaded fasteners to reduce friction upon assembly. Designed for thread forming fasteners such as Taptite and other Trilobular screws, precote® Top 300 has optimal friction values upon assembly. precote® Top 300 can prevent galling, torque chattering and “cold welding” upon installation and can be applied on all threaded materials including plastics.
precote® 709 is a dry film coating for threaded fasteners which helps prevent galling and seizing on assemblies which require higher pre-load torque. Not only resistant to higher temperatures, precote® 709 is also resistant to lubricants, fuels, hydraulic fluids and most commercial solvents. precote® 709 is especially suited for assemblies where galling and cold welding during assembly and disassembly are common.
