Specification

Tough removable screw retainer and sealing compound u2013 single-handed dispensing system

Ideally suited for screw connections exposed to high stresses

100% sealing u2013 no additional fixings necessary
Protects against corrosion due to friction, and against rust

Can only be removed once heated up to 300u00b0C!

Removable under normal conditions only by means of special tools and/or under certain temperatures

Excellent media and heat resistance

Universal products with broad range of applications

Prevents removal e.g. due to vibrations and shocks

No unwanted backup problems such as mechanical screw locks

Highly resistant

Resistant to a large number of bases, gases, solvents, oils and fuels

Silicone-free

DOS system:

Practical one-handed operation thanks to the clever turn lock

You always have one hand free.

Continuously adjustable dispensing system

Dispensing can be adjusted to suit the application, and to keep consumption and costs to a minimum.

No residue material in dispensing neck

Costs optimised thanks to emptying with virtually no remaining product

Notice

The following plastics can be affected in the event of prolonged exposure: ABS, celluloid, polystyrene, polycarbonate (Makrolon), PMMA (Plexiglas), polysulfone, SAN (Luran, Tyril), Vinidur, vulcanised fibre and painted surfaces. We always recommend that you conduct your own tests.

The usage instructions are recommendations based on the tests we have conducted and our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. Insofar as our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee consistent quality of our products. We reserve the right to make technical changes and further develop products.

Application

For securing, fastening and sealing bolts, stud bolts, nuts, thread inserts and threaded plugs, all of which do not normally have to be detached.

Automotive and commercial vehicle industry, metal and tool manufacturing, shipbuilding, machine and engine construction, electrical and electronics construction.

Instructions

The material is applied evenly and in liquid form directly to the oil, grease and dust-free surface. For cleaning and degreasing, we recommend brake cleaner. The cleaner the surface, the more secure the bonding. These adhesives harden anaerobically, which means that they only harden where no atmospheric oxygen comes into contact with the adhesive. For this reason, the containers are also only filled to approx. 3/4 full. At the same time, the hardening speed is still being influenced by the catalytic effect of metal and the gap width. The more "passive" the material and the thicker the gap, the more slowly the material hardens.

Passive materials: nickel, zinc, tin, precious metals, aluminium with minimal copper and/or manganese content, high-alloy steel, oxide or chromate coats, plastic, glass and ceramic.

Active materials: Steel, brass, bronze, copper, aluminium (copper content greater than 1%).

Permeation is the process by which a chemical moves through the material of a protective glove on a molecular level. The time from the initial contact between the chemical and the glove to the permeation of the material is the breakthrough time.

Important information:

The information given is based on experience and laboratory conditions and is designed as a guide. However, the actual suitability of a glove depends on the individual conditions of its use and must be confirmed by an appropriate test under operational conditions. Given the variety of materials and chemicals used, the possibility of incompatibility or usage problems for the wearer cannot be excluded in individual cases. We would be happy to advise you about optimum solutions.
