Working Conditions

Ensure to work in a well-ventilated work space. The working temperature should range between 5 and 30 °C.

Preparation of the substrate

The substrate must be clean, dry and free from grease. It is recommended to clean the surface with acetone. Roughening or structuring the surface will improve the adhesion. In some cases a corona or plasma treatment will lead to remarkable improvements in adhesion.

Application of the primer

The primer should be applied as a very thin film using a soft brush or a lint-free cloth. A coat weight of 40 – 60 g/m² is recommended depending on the roughness and absorbency of the ground.

Curing of the primer

The Primer has to be heated for at least 30 minutes at 50 °C.
After the primer treatment the surface should be well protected from any dust or contamination. The adherent should be applied soon – a maximum open time of 6 hours should be respected.

Application of the adherent

Apply and vulcanise the silicone elastomer mixture as recommended in the respective Technical Data Sheets.
