Highly adhesive, permanently elastic sealing compound

• Very good adhesion to plain, primed and painted sheet metal
• Compensates for tolerances/bridges gaps
• Long-term, reliable seals

High degree of stability

• Very easy to smooth
• Spatula and brush application
• Can be structured with brush or smoothing stick

Short skin formation time

The sealant surface is tack-free after a short period.

Can be painted over quickly

Thanks to the quick skin formation time (perform preliminary tests to check paint compatibility).

Approved for use with foodstuffs (ISEGA certificate)

• Harmless to health in hardened state
• Suitable for sealing in food processing areas

Non-corrosive

Prevents metal corrosion.

Virtually odourless

Silicone-free

Notice

Do not allow this product to come into contact with alkyd-resin paint systems. Not suitable for glass groove sealing in areas in which UV back reflection can occur. Direct exposure to sunlight can result in slight surface yellowing. It is essential to use Würth B and S Primer products in order to achieve optimum adhesion results! This is especially important with critical surfaces, such as non-ferrous base metals (copper) and galvanised materials. For smoothing, use Würth sealant smoothing agent.

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.

For permanently elastic, highly adhesive sealing of overlapping seams, spot-welded seams, visible joints, sheet-metal connection joints and folded seams, both indoors and out. Excellent adhesive strength on a wide range of materials and surfaces such as metal, paint, wood, stone, concrete and plastic (polyester and hard PVC). Not suitable for PE, PP, PTFE, silicone rubber, polystyrene and softened plastics.

Instructions

The application surfaces must be clean, dry and free of grease. Optimum adhesion results are guaranteed by pre-treating the surfaces with B and S Activating Cleaner and B and S Primer for Metal or B+S Primer for Plastic/Wood/Stone. This is especially important with critical surfaces, such as non-ferrous base metals (copper) and galvanised materials. Material that has not cured can be removed using B and S Remover.

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.
