2. Bonding without permit
For all other systems which do not possess an ETA (European Technical Approval), the window/facade contractor must seek specific approval from the local authority o the basis of ETAG 002.
Basis:
- Structural dimensioning of the bonding
- Adhesion testing on original profiles/silicone with ETA certification 2-component silicone DC 993 (ETA 01/0005)
- Factory internal control similar to ETAG 002 by ISO 9001 certified companies
Preferred bonding surfaces of profiles:
- Aluminium anodised
- Stainless steel
The original extrusion/profile (coating, anodising batch) is specifically tested for adhesion properties and approved by Dow Corning prior to bonding.
Permitted bonding surfaces of glass with Silicone DC 993:
- Float glass
- Coated glass COOL-LITE (SS 108, PB 114 N, ST 150), ANTELIO (clear, Silver)
- EMALIT-H, SERALIT LITEX-H
We recommend that only materials which have been tested for compatibility are used for Weather Sealing, e.g. Dow Corning DC 791.
