Silica gel 硅胶

LOCTITE 518 is a medium-strength, general purpose gasketing product with excellent contamination tolerance. Ideal for use on casted iron, steel and aluminum flanges.
LOCTITE 518 cures when confined in the absence of air between close-fitting metal surfaces. It is an anaerobic gasketing material designed for use on rigid iron, aluminum, and steel flanged mating surfaces. LOCTITE 518 fills gaps up to 0.25mm and forms a flexible, chemical-resistant seal that will not tear or decay. Parts disassemble easily, even after extended service. Typical applications include sealing close-fitting joints between rigid metal faces and flanges. It is also used as a formed-in-place gasket on rigid flanged connections, e.g. transmissions and motor housings.

LOCTITE 510 is a high temperature and chemical resistant gasketing product that is ideal for use on rigid flanges.
LOCTITE 510 is a high temperature resistant anaerobic sealant which cures when confined in the absence of air between close-fitting metal surfaces. Typical applications include sealing rigid flange faces on transmissions and motor casings. It ensures an instant, low-pressure seal. The product increases the torque capacity of assembled flanges.

General purpose, one-part silicone adhesive sealant which cures at room temperature to form a tough rubber seal.
LOCTITE SI 593 is a black, general purpose, one-part silicone adhesive sealant which cures at room temperature to form a tough rubber seal. Will not slump in overhead or vertical applications. It has been formulated to withstand extreme temperature cycling, UV light, and ozone. It CANNOT be painted and is also available in clear and white.
