LOCTITE 573

Gasketing Product - slow curing. Ideal for use on machined and rigid metal flanges.


LOCTITE 573 seals close-fitting joints between rigid metal faces and flanges. The product cures when confined in the absence of air between close-fitting metal surfaces. Typically used as a form-in-place gasket on rigid flanged connections, e.g. transmission and engine casings, etc. It is the ideal product for part assembly jobs extending over several hours. The nature of LOCTITE 573 reduces the migration of liquid product after application to the part.


Your benefits
◾Typically used as a form-in-place gasket on rigid flanged Connections
◾Ideal for sealing large, rigid metal flanges or flanges where assembly may take up to several hours


Technical Data
◾Colour: Green
◾Max. gap size: 0.1 mm
◾Service temperature range: -55 to +150°C
◾Tensile shear strength in N / mm²: 1,3
◾Substrate to be sealed: Metals
◾Fixture time steel: 9 h
◾Fixture time aluminium: 12 h

LOCTITE 638

Retaining Compound - high strength. General purpose. Fast curing.

LOCTITE 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25 mm. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It not only works on active metals but also on passive substrates, exhibiting robust cure performance. The product offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants.

Your benefits
◾High temperature resistance
◾Tolerates minor contaminants, including industrial oils
