LOCKCOTE or PRECOTE: With unique double-capsule sealing technics, it is applied to new-type tiny capsule anti-loose processing. The resin and hardener are sealed on screws. When the fasteners are installed, they will break, which makes the chemicals mix together to guarantee the strong binding power. PRECOTE5 is applied to the seal of lower intensity round and conical screw thread to prevent gas or liquid from leaking, which is strongly gasoline-resistant and diesel oil-resistant (white). PRECOTE30 is applied to medium intensity and can be easily uninstalled under high temperature for a long time with heat-resistant up to 300°F(150°C) (yellow). PRECOTE80 is applied to standard anti-loose processing with high strength and heat-resistant up to 340°F(170°C) (red). PRECOTE85 is applied to high strength screws and high stress screws with heat-resistant up to 300°F(150°C) (green).
