Es liegt in der eigenen Verantwortung des Käufers, die Angaben sowie die Geeignetheit unseres Produktes für den vorgesehenen Einsatzzweck vor dem Gebrauch zu überprüfen.

Processing
The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material such as dust, dirt, rust, oil and other contaminants. Non-porous substrates should be cleaned with a solvent and clean, lint-free, cotton cloth. Remove residual solvent before it evaporates with a fresh clean, dry cloth. For application from cartridges cut thread open, fix nozzle on top and cut to required bead size. The sealant can be applied in beads or layers. It requires moisture in order to cure.
The curing time can take longer at lower temperatures, lower humidity or by low volume of air exchange.
Restrictions on use WACKER® 180 - HIGH TEMPERATURE should not be used on substrates such as marble, concrete, fibrous cement and mortar, as the product releases acetic acid during curing. WACKER® 180 - HIGH TEMPERATURE should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion. WACKER® 180 - HIGH TEMPERATURE may be discolored in contact with some organic elastomers, e.g. EPDM and neoprene. WACKER® 180 - HIGH TEMPERATURE is not suitable for applications involving contact with natural stone, such as marble, granite, quartzite, as it can cause staining. WACKER® 180 - HIGH TEMPERATURE is not recommended for sealing of aquarium or for long term use under water. WACKER® 121 - AQUARIUM has been specifically developed for aquarium applications. WACKER® 180 - HIGH TEMPERATURE must not be used for structural glazing bonding. WACKER® 180 - HIGH TEMPERATURE is not suitable as cylinder head gasket or for parts that are constantly exposed to fuels (petrol).
It is the responsibility of the user to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coatings or organic plasticizers can lead to discoloration of the sealant. Cleaning agents and gaseous emissions can damage the sealant in its function or change its appearance. WACKER cannot make a general statement to the compatibility of all these varying materials with the sealant. In case of doubt the user shall conduct appropriate preliminary tests.

 

Application
- Sealing of connecting and expansion joints exposed
to high temperatures
- Sealing of joints exposed to constant temperatures
of 250 °C (e.g. industrial ovens and chimney
constructions)


Adhesion

WACKER® 180 - HIGH TEMPERATURE exhibits excellent primerless adhesion to most non-porous siliceous materials (e.g. glass, tiles, ceramics, enamel, glazed tiles); metals (e.g. aluminum, steel); impregnated, varnished or painted wood; and some plastics.
Users must carry out own tests due to the great variety of substrates.
The adhesion can be improved in many cases by pretreatment of the substrate with a primer.

Verpackung / Gebinde

WACKER® 180 - HIGH TEMPERATURE is usually supplied in standard size cartridges that fit all standard caulking guns.

Lagerung

The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
