Description

The silicone sealant is MEKO-free and is therefore classified as low-emission and environmentally friendly and has been awarded the EMICODE EC1 Plus label

Meets the requirements for window glazing in accordance with DIN 18545, Part 2, Sealant Group E

Excellent adhesion to wood, metals and many plastics

Excellent compatibility with most commercially available paint and glazing coatings

Building material class B2 according to DIN 4102

Does not have a tacky surface

High degree of abrasion resistance and good smoothing properties

Permanently elastic

Short stringing

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

The EMICODE classification system awards labels to construction products that comply with the very stringent health and environmental requirements of recognised institutes. The lowest-emission products bear the EC1plus mark.

The slightly milky colour of the transparent version is an indication of the excellent quality of the silicone and is related to the composition of the silicone

Not suitable for bonding or filling cavities

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

Remove excess smoothing agent on glass and frames immediately after application to avoid smearing.

Can be used for sealing between frames and laminated glass. There must not be any direct contact between the sealant and the laminated glass film in the process.

Yellowing on contact with white alkyd resin paints cannot be excluded

When hardening, gives off an odour typical of silicone. This odour is no longer present once the curing process is complete. With larger joint dimensions, the silicone-like odour may be present for longer.

Matt colouring

Silicone has a tendency to yellow in dark areas where there is no UV exposure

Avoid contact with VKP tape

Contact with substances containing plasticiser, e.g. butyl/bitumen, can cause discolouration

Material incompatibilities can lead to discolouration of the sealing joints, especially in the case of transparent and white sealing compounds

Experience has shown that colouration effects on the sealing joint cannot be ruled out on surfaces coated with alkyd resin paint and/or similar coating systems. In addition, emissions from the surfaces to be sealed and influences from the direct ambient atmosphere, such as vapour, dust and smoke (especially tobacco smoke), have negative effects on the colouring of the sealing joint. The vapours from the materials mentioned usually originate from primers, solvents, disinfectants, cleaning agents and/or surface treatments.

Meets the requirements of DIN EN 15651 Parts 1/2/3 Sealants for façade elements/glazing/sanitary joints

Fire behaviour: Class E

Stability under load: < 3 mm

Volume loss: < 10 %

Adhesion/expansion under pre-stress after being immersed in water: Passed

Adhesion/expansion on exposure to heat, water and artificial light: Passed

Elastic recovery: ≥ 70 %

Tensile stress value for tensile behaviour: < 0.4 MPa

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 experiences. Carry out your own tests before each application.

Usage

Application area

For window glazing and sealing connection joints in wooden, plastic and aluminium windows

Sealing indoor and outdoor expansion joints under high load, such as door, wall, floor, ceiling and window sill joints and gutters

Can be used for sealing between frames and laminated glass

Suitable for buildings, in glass and window construction and for glass seam sealing

Can be used in the sanitation sector

Instructions

The surface must be load-bearing, clean, dry and free from grease, rust and water

Do not use in heavy rain

Observe the joint dimensioning

Prime the joints with PE back-fill material

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

Smoothing agents must only be used before the skin formation time and must be completely levelled after use with a smoothing tool. Excess product next to the joint must also be removed immediately, otherwise staining may occur.
