Name	Short Description
SILLITIN Z 86 puriss	Standard product, balanced profile of properties.
SILLITIN Z 89 puriss	Same as Sillitin Z 86 puriss, but also for brighter applications.
SILLITIN Z 86	For lower requirements for dispersion properties.
SILLITIN Z 89	For lower requirements for dispersion properties.
SILLIKOLLOID P 87 puriss	Same as Sillitin Z 86 puriss, but with slightly higher tensile strength and tear resistance, higher viscosity.
AKTISIL AM	Same as Sillitin Z 86, but with better mechanical properties like higher tensile strength, better compression set and abrasion resistance, partly higher adhesive strength and chemical resistance.
AKTISIL PF 777	Same as Sillitin Z 86, but with higher rheological activity, improved water resistance.
SILFIT Z 91	Same as Sillitin Z 89 puriss, but with highest brightness and color neutrality, lower viscosity, faster crosslinking reaction.
AKTIFIT AM	Same as Silfit Z 91, but with better mechanical properties, partly higher adhesive strength and chemical resistance.
AKTIFIT Q	Same as Aktifit VM, but with higher polarity through methacrylic groups.
AKTIFIT PF 111	Same as Aktifit VM, but with higher rheological activity.
AKTIFIT PF 115	Same as Aktifit AM, but hydrophobic, very low moisture content without increase under humid climatic conditions, according to polarity moderate rheological activity.
