Specification

Special acrylic sealant that minimises development of cracks and discolouration of emulsion paints at the joint

After only a few hours, it can be plastered and painted over with high-quality emulsion paints

Reduces the risk of development of cracks and of discolouration of the applied emulsion paints

Resistant to ageing, weathering and UV

Plastoelastic

Free from silicone, solvents and phthalates

Our Acrylic Special sealant carries the "Blauer Engel" eco-label.

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

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.

Tested in accordance with EN 15651 Part 1

Fire behaviour: Class E

Release of chemicals hazardous to health and/or the environment: See safety data sheet

Stability under load: ≤ 3 mm

Volume loss: ≤ 25%

Adhesion and expansion under pre-stress after being immersed in water: ≥ 25%

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.

Application

Application area

For sealing between walls and ceilings, and on interior and exterior door frames.

Instructions

Adhesion surfaces must be clean, dry and firm

A primer, e.g. with Silicone primer, improves the adhesion for absorbent or porous surfaces.

Please observe the "General Notes on Application for Sealants" overview sheet. Further information in the technical data sheet.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with v
