Areas of Application
- Sikaflex®-265 is designed for direct glazing applications in both the OEM and repair markets, and is suitable for use with mineral glassbased windows. Before installing laminated safety glass windshields incorporating heating elements or radio aerials in the PVB sandwich layer, we recommend to contact Sika’s Technical Service Department for advice.
- Sikaflex®-265 can be tooled to a very fine finish. It contains special stabilizing ingredients to enhance its UV resistance, therefore it is suitable for use in exposed joints.
