Description

The sealant can be coated/plastered, excellent adhesion to most common paints and brushes

Due to the wide variety of paint and lacquer formulas available, we recommend that you always carry out preliminary testing in order to rule out any interactions. Caution: Sealant joints that have been fully painted over tend to crack when movement occurs in the joint, as the applied paint is generally less elastic than the sealant.

Highly elastic

Broad adhesive range on a range of standard construction surfaces

Building material class B2 according to DIN 4102

Silicone-free

Resistant to ageing, weathering and UV

Odourless

Our products featuring the EMICODE label are low emission/environmentally compatible. The EMICODE classification system awards labels to construction products that comply with the very stringent health and environmental requirements of recognised institutes.

Notice

Not suitable for use in building construction joints in accordance with DIN 18540

Due to the large number of varnish and glazing formulations, preliminary testing is required in order to rule out any interactions

Take care with sealant joints that have been fully painted over. These tend to develop cracks when movement occurs in the joint, as the applied paint is generally less elastic than the sealant and then causes cracks to form in the paint.

The setting speed is dependent on the application temperature, the weather and the surface moisture. The setting speed is greatly delayed in cold, damp weather.

Discolouration may occur in wood containing tannic acid

For vertical joints, please observe the run-off behaviour of the sealant

May cause corrosion on metals such as steel, copper and zinc-plated surfaces

Standing water should be prevented in the acrylic joint as this can lead to erosion

Acrylic is very unstable in terms of water absorption and release. Since the diffusion behaviour also changes as a result of the differences in water adsorption in the material, neither the water vapour diffusion resistance (μ) nor the diffusion-equivalent air layer thickness (SD) can be measured on this material in accordance with DIN EN 12572. The value of 5,000 is the average value obtained through testing.

Not to be used in conjunction with pre-compressed sealing tapes

Not suitable for bonding or filling cavities

Due to the large number of varnish and glazing formulations, always carry out your own tests on the area first, especially on alkyd resin paints and powder-coated aluminium

Tested in accordance with EN 15651 Part 1

Fire behaviour: Class E

Stability under load: ≤ 3 mm

Volume loss: ≤ 25 %

Tensile behaviour after immersion in water (at 23°C), ductile: ≥ 100 %

Durability: Passed

EMICODE EC1plus: Very low emissions: The EMICODE classification system distinguishes the environmental and health compatibility of construction products. The lowest-emission products bear the EC1plus mark.

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.

Usage
