ELASTOSIL^® eco 7770 P

Application fields

• application on natural stones, e.g., marble, granite, sandstone, and quarzite
• sealing of connecting and expansion joints in the building industry
• sealing of joints in sanitary applications
• sealing of joints between glazing and supporting structures (frames, transoms, mullions)

Processing

Surfaces that will come into contact with the sealant must be dry, clean, and free of dust, dirt, rust, oil, or similar contaminants. Non-porous surfaces should be cleaned using a solvent and a clean, lint-free cotton cloth. The area must then be immediately wiped dry with a second clean cloth before the solvent evaporates.

It is the responsibility of the user to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coating materials (e.g., paints, varnishes, and glazes) or organic plasticizer containing rubbers (e.g., EPDM, butyl, and neoprene) can lead to discoloration or other impairments like loss of adhesion of the sealant. Substances that come into direct contact with the sealant after application, such as cleaning agents, or indirect contact through outgassing, can impair the function of the sealant or alter its appearance.

Due to the wide variety of possible materials and substrates, especially with plastics, WACKER cannot make any general statements regarding compatibility or adhesion. In case of doubt, users must carry out their own preliminary tests.

A decrease in temperature or humidity, as well as restricted air circulation, can significantly extend the time required for complete curing.

Adhesion

ELASTOSIL^® eco 7770 P adheres excellently to most substrates commonly found in sanitary areas—even without prior treatment with primers—such as glass, tiles, ceramics, glazed tiles, enamel, and clinker, as well as metals like aluminum, steel, zinc, and copper, painted, stained, or impregnated wood, and many plastics.

Users must carry out their own tests due to the great variety of substances. The adhesion can be improved in many cases by pretreatment of the substrates with a primer. If adhesion difficulties arise please contact our technical service.
