WEICONLOCK^®
Anaerobic Adhesives and Sealants

• locking • retaining • sealing • gasketing

• easy application
• clean processing
• better dosing

The ideal solution for construction, production, maintenance:

• one-component
• fast curing
• ready-to-use
• solvent-free
• non-shrinking
• vibration-proof

WEICONLOCK products are high quality anaerobic adhesives and sealants on the basis of special methacrylate resins, especially made for economical threadlocking, retaining and sealing of threaded, cylindrical and pipe assemblies.

The characteristic feature of WEICONLOCK is the curing in contact with metal while deprived of air. It provides a shock- and vibration-resistant joint with excellent resistance to chemicals and solvents. Due to its liquid consistency WEICONLOCK completely fills the gaps, thus giving protection against leakage and fretting corrosion.

Special features and benefits

WEICONLOCK is simple, easy to use and very economical. Handling strength is reached within a few minutes and fi nal strength within a few hours at room temperature. Metering and mixing is not necessary, there is no pot life to be respected and product wastage is minimised.

In many respects, WEICONLOCK is superior to conventional methods of assembly.

The use of WEICONLOCK

• avoids expensive down-times
• reduces production costs
• improves operational reliability
• reduces assembly times.

Applications

Offering different grades of strength and viscosity, WEICONLOCK is suitable for a wide range of applications:

• for locking, fastening and sealing of screw connections from M5 to M80, for pipe joints as well as coarse threaded connections up to 3".
• for reliable retaining of bearings, bushings, bolts and other press or slip fi tted connections.
• for sealing and locking hydraulic and pneumatic pipe connections.

In addition, WEICONLOCK is highly recommended for use in flange sealing, replacing conventional gaskets in many cases. The benefi ts are:

• no expensive stock keeping
• no problems with complicated seals
• no setting of the seals (unlike solid gaskets)

WEICONLOCK is suitable for all metals and certain plastics. It can be applied either manually or semi / fully automatic.

As cost-effective problem solvers, WEICONLOCK products are indispensable in many sectors of industry:

• automotive industry
• engine and plant construction
• manufacture of pumps and pipes
• hydraulic and pneumatic equipment
• precision mechanics
• in electrical engineering and electro-technics and in nearly all fields of repair and maintenance.

General Information

Pretreatment of Surface

In general, WEICONLOCK does not require special pretreatment as slightly oily surfaces (e.g. on ‘as received’ parts) will be tolerated. However, best results will be achieved on cleaned, degreased parts (use WEICON Cleaner S). If required, the parts should be slightly roughened.

Application

WEICONLOCK is ready for use and should be applied evenly direct from the bottle/tube with the dispensing tip (avoid direct contact of dispensing tip with metal). On pressfi tted parts and larger cylindrical assemblies a thin and uniform layer should be applied on both surfaces. In the case of threaded blind holes fi ll suffi cient quantity in the bore hole. On screws and bolts, apply WEICONLOCK around the thread. Do not pour back into the bottle any WEICONLOCK fluid which had contact with metal; even smallest metal particles will cause the content of the bottle to cure. In series construction, the use of manual or automatic applicators is recommended.

Choice of product

WEICONLOCK is available in different categories of strength:

• low strength = easy dismantling
• medium strength = dismantling possible with ordinary tools
• high strength = cannot be dismantled mechanically other than by destruction

Different viscosity grades enable the locking of screws of smallest diameter up to M80/R3".

WEICONLOCK Activator F

The cure time can considerably be reduced by pretreatment with WEICONLOCK Activator F, which is recommended for all passive surfaces and which is indispensable at low ambient temperatures (0°C and up) and for large gaps. On non-metallic surfaces, WEICONLOCK is made effective by use of the activator.
For applications where passive surfaces are involved, where the use of an Activator is not wanted yet where a rapid cure is required, a solution could be the use of types AN 302-60, AN 302-80, AN 306-10 and AN 306-30. These special types allow to reach handling strength much quicker than any standard type (without Activator).

Curing

WEICONLOCK remains liquid as long as in contact with air. The cure starts when WEICONLOCK, between the interfaces, comes into contact with metal under the absence of air. The cure time is dependent on the selected type, the ambient temperature and the material.

Dismantling

Connections of low and medium strength can easily be loosened with ordinary tools; high-strength bonded parts can be disassembled by being heated to min. 300°C. Cured residues of WEICONLOCK can be removed mechanically or with WEICON Sealant and Adhesive Remover.

Storage

WEICONLOCK can be stored in the unopened original container for at least one year at room temperature. Keep away from heat sources and direct sunlight. The air in the bottle/tube keeps WEICONLOCK liquid.

Safety precautions

WEICONLOCK adhesives and sealants generally do not cause allergic reactions of the skin. However, in isolated cases where skin is continously bruised or micro-lacerated sensitisation may occur. Therefore, extensive and direct contact with the skin should be avoided, e.g. by use of WEICON Hand Protective Foam.
