Loctite 573 - 250 ml surface seal

Product detailed description

Loctite 573 (IDH 142614 / 57341) – Long-cure surface sealant

Loctite 573 is an anaerobic sealant designed for surface sealing of metal flanges. which are exposed to low pressure and vibration. Due to its thixotropic consistency, it is ideal for applications where a longer assembly time is required, for example on gearboxes and engine blocks. It cures without air access in the gap between the bonded metal surfaces and ensures a reliable seal even with irregular surfaces. 

Advantages:

• Slow curing allows for longer assembly times. vibrations and chemicals, including oils, glycols and coolants.
• Ability to fill gaps up to 0.1 mm without risk of part deformation.
• Flexible sealant that easily conforms to metal surfaces without dripping.
• Excellent properties at .

Application: rigid metal flange connections, for example in gearboxes, engine blocks, pumps, valve covers and other machine assemblies. Due to its slow cure time, the product is ideal for applications where more time is required for assembly. application:

• Surface preparation: For thorough degreasing and dirt removal, use Loctite SF 7061 cleaner, which ensures gentle but effective cleaning. hydrocarbons.

• Removal of sealant and adhesive residues: If you need to remove old sealant, adhesives or other materials from a bonded surface, Loctite SF 7200 is the ideal choice. Its application is simple – just apply and let it work, which makes the material easy to peel off.

• Surface activation: When applying anaerobic sealant at temperatures below 5 °C, it is recommended to first treat the surface with Loctite SF 7240 or Loctite SF 7649. The activator will accelerate curing on passive metals or at low application temperatures. Product: For precise and effective application of adhesives or sealants, we recommend using the Teroson Staku Loctite 97002 manual application gun. These professional tools are designed for precise dosing and ensure optimal control when applying the material. cartridge types and packaging.

• Surface cleaning: For the thorough removal of old deposits and dirt, including oils, greases and other industrial dirt, use Loctite SF 7850, which is suitable for effective hand cleaning. This biodegradable cleaner removes oils, greases and other

Typical properties:

• Before curing: Medium viscous green paste that does not flow from the application site due to thixotropic properties.
• After curing: Flexible seal with high resistance to vibrations, chemicals. micro-movements.

Use when applying:

1. Surface preparation: Surfaces must be clean and degreased. The use of cleaners such as Loctite SF 7063 is recommended.
2. Application: Apply the product by hand to the flanges.
3. Assembly: Assemble the flanges immediately and tighten to avoid a large gap during curing.
4. Curing: The product reaches full strength after 24 hours at room temperature.
