- Very good adhesion on many materials
- Low modulus according to ISO standards
- Resistant against UV-radiation, rain, frost, wind, ozone and extreme
- Excellent adhesion properties on glass, laminated glass, coated
aluminium, galvanised steel, concrete and masonry
- Weatherseal in curtain wall applications
- Ideal for expansion, perimeter, connection and other movement joints
