Everbuild Tecnic® Silicone 996
Everbuild Tecnic® Silicone 996 is a low modulus, neutral cure silicone sealant which is suitable for use on glazing and most building and constructions joints, both porous and non-porous. Ideal for use on glass to glass joints.
- Excellent tooling properties for large scale construction and glazing applications.
- Excellent adhesion—adheres to most common surfaces including glass, metals, plastics and wood (painted or unpainted), uPVC and polycarbonate.
- Excellent external weather properties.
Usage
- Glass to glass joints.
- Perimeter pointing internally and externally around PVCu /wood and all other window frames.
- Sealing and as an adhesive onto PVCu, plastic trims and components.
- Weather sealing and joint sealing to pre-formed panels and cladding panels.
- Weathersealing on structural glazed assembly
- Bedding I.G Units
- General glazing sealing and draught proofing.
- Glass to glass and glass to aluminium sealing.
- Parapet and roof weather sealing applications.
- Suitable as an expansion joint sealant.
Advantages
- Excellent tooling properties for large scale construction and glazing applications.
- Excellent adhesion—adheres to most common surfaces including glass, metals, plastics and wood (painted or unpainted), uPVC and polycarbonate.

Joint Design
Joint Dimensions
For maximum movement accommodation, it is recommended that:
1/ The sealant joint width should be no less than 5 mm.
2/ Joint depth should be half width e.g. 30 mm wide and 15 mm deep.
Joint depth may be adjusted to the correct size using EVERBUILD® JOINT BACKER ROD. Bond Breaker Tape can be used to prevent 3 sided adhesion in situations where EVERBUILD® JOINT BACKER ROD would have a negative effect on joint dimensions.

SUBSTRATE PREPARATION
Everbuild Tecnic® Silicone 996 does not require a primer on most common surfaces, although adhesion tests are recommended prior to full scale application. If the joint is likely to be immersed or if adhesion is poor (especially on porous surfaces) use EVERBUILD® SILICONE PRIMER P1 / Sika® Primer 3N. To improve adhesion (if required) to non-porous surfaces, prime with EVERBUILD® SILICONE PRIMER NP2 / Sika® Aktivator 205.
The surfaces to be must be clean, dry and free from dust, grease and other contaminants. Remove dust with compressed air. Degrease by using a solvent soaked pad, followed by wiping with a clean cloth. Following cleaning procedure and materials are recommended:
| Glass | Degrease with alcohol, MEK |
| Aluminium | Degrease with alcohol, MEK |
| Other metals | Lightly abrade then degrease as above |
| Wood | Lightly abrade surface then remove dust |
| Plastics | Degrease using an agent recommended by plastics manufacturer |
| Concrete and other alkaline surfaces | Brush and remove dust |
