Loctite 5203 - 300 ml surface seal

Product detailed description

Loctite 5203 (IDH 170682 / 24197) – Low Pressure Gasket

Loctite 5203 is an anaerobic sealant designed for sealing rigid metal flanges. This product cures in the absence of air between closely fitting metal surfaces to form a durable and flexible seal. The product is ideal for applications where low pressures and easy disassembly are required, and is particularly suitable for machined aluminum flanges. Loctite 5203 Gasket offers fast cure, excellent chemical resistance and easy removal from surfaces. 20 minutes.

Application:
Loctite 5203 is designed for sealing rigid metal flange joints, for example in gearboxes, covers engines and other industrial equipment. Typical applications include machined metal surfaces, especially aluminum, where low strength is required for easy removal.

Use for application:

• Surface preparation: Loctite SF 7063. If you prefer more environmentally friendly products, Loctite SF 7061 is an ideal choice, which provides 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 leave to act, which will easily peel off the material. Beware of painted and plastic parts.

• 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 accelerates 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. Ergonomic shapes, easy handling. Suitable for working with various types of cartridges and packages.

• Surface cleaning: To thoroughly remove old deposits and dirt, including oils, greases and other industrial dirt, use Loctite SF 7840. This universal water-based cleaner is biodegradable and is ideal for effectively cleaning a variety of surfaces without damaging the material.

• Hand cleaning after work: After completing the application, use Loctite SF 7850, which is suitable for effective hand cleaning. This biodegradable cleaner will remove oils, greases and other dirt. Choose the right LOCTITE gasket for your application.
