Description, instructions for use and types of Loctite sealants

What is anaerobic sealant

To understand the essence of the action of an anaerobic type sealant, you need to know its meaning. These products are acrylic elements that are placed in special containers where air ingress is excluded. In this form, without loss of characteristics, the composition can be stored for approximately 12 months.

When the sealant is applied to the metal, the curing process begins in the narrow crevices of the material. As a result, the layer obtains high strength properties.

general description

Loctite sealant usually serves as a gasket between various components in auto repair. This helps create reliable protection against leaks; load-bearing parts receive uniform load distribution on the mechanisms and components of the machine. The sealant in the syringe is easy to apply; it is produced using modern technologies. Completely fills the required areas. Professionals note better efficiency from the use of sealant compared to standard compression gaskets, the use of welds, etc.

It is not advisable to use Loctite 574 in pure oxygen environments or in oxygen-rich systems. Loctite 574 should not be used as a sealant for chlorine and other strong oxidizing agents. Loctite 574 is generally not recommended for use on plastics (especially thermoplastic materials where stress cracking of the plastic may occur).

Brand Features

Loctite sealant is produced in a syringe by the famous brand Henkel, which has long established itself in the construction market as producing highly effective products. The company began production of this product in 1997; over time, it tried to make the composition more durable and reliable. And the result is a high-quality product that optimally copes with car repair work.

Loctite 574 - Durable Metal Flange Seal - Universal 50 ml

Application: Sealing tightly fitted metal surfaces and flanges. Forming gaskets in place. Withstands slight pressure immediately after the connection is assembled. Loctite 574 fills micro-irregularities and gaps up to 0.5 mm and cures quickly.
Operating temperature: up to +150°C

Conditions of applicability: Anaerobe = polymerizes in the absence of air in small gaps between active metal surfaces (or in the presence of the loctite7649 activator). For polymerization, 2 factors are required: absence of air + active surface (or loctite7649 activator). For polymerization, a small (up to 0.25 mm) gap between the parts being connected is required (decent thread quality) + an active metal surface, or the liquid loctite7649 activator. Active surfaces include carbon steel, cast iron, brass, bronze, copper.

Chemical Resistance: Tests consisted of exposing the polymerized product to the specified temperatures and then testing it at 22°C.

Loctite 574 is not recommended for use in pure oxygen environments and/or oxygen rich systems.
Loctite 574 should not be selected as a sealant for chlorine and other strong oxidizing agents. Loctite 574 is generally not recommended for use on plastics (especially thermoplastic materials where stress cracking of the plastic may occur). Instructions for use:

To achieve optimal performance, the surfaces to be joined must be clean and free of grease.
Loctite 574 is designed for tight fitting flange connections with close clearance.
Loctite 574 is applied to the flange surface in an even layer or through a stencil
To test the tightness immediately after assembly, the connection can be subjected to low pressure (less than 0.05 MPa).
Flanges must be tightened immediately after assembly to avoid movement.
The rate of polymerization depends on the ambient temperature and the size of the gap between the mating parts.

Storage: Loctite 574 Anaerobic Flange Seal Gasket should be stored in a dry place in closed containers at a temperature of 8 - 21°C unless otherwise stated on the packaging. Storage at temperatures below 8°C or above 28°C may adversely affect the properties of the sealant. To prevent deterioration of unused product, do not return it to the original packaging.

Typical Applications

Loctite is suitable for joining parts. But we can highlight the area of application that is chosen most often. It is typical to apply sealant for sealing work with metal threaded connections. Separately note the use for stainless steel without the need for surface activation.

Loctite is suitable for joining parts.

Types of compositions

The brand produces a variety of types called Loctite, they are suitable for almost all components in the car. The line includes adhesives and sealants. Can be used as a processing material for fastening joints and a gap sealer.

Threaded fasteners

Their purpose is to fix fasteners and prevent the hardware from unscrewing itself. Their consistency is viscous and semi-solid, they penetrate well into the material, closing the gaps between the bases. Hardening occurs at temperatures of +20-25 degrees, suitable for metals. This is a one-component type, withstands vibration loads and does not allow leaks.

Thread sealants

Necessary to create a seal on threaded connections, this avoids the penetration of liquid solutions and gases. The dried layer copes with increased loads. The following properties are distinguished:

Ease of use;
Does not shrink;
Replaces gaskets;
High degree of resistance to mechanical and vibration loads;
High level of rust protection.

The ability of Loctite products to complete polymerization in an airless environment is noted.

Flange sealants

Used instead of cushioning materials. They are distinguished by their uniform closing of gaps, resistance to aggressive influences, and a completely sealed coating is created. It compacts quickly and does not shrink after shrinkage; it has a good level of resistance to high pressure.

You can choose different forms of sealants - paste or gel.

Used instead of cushioning materials.

Shaft-sleeve clamps

Suitable for working with the fitting of car parts in the form of cylinders: bearings, bushings and shafts. In order for the part to shrink correctly and reliably, a compound must be applied to it, this helps balance the load. Manual or semi-automatic tools can be used for distribution.
