DESCRIPTION

LN7 is the most versatile sealant available. It gives off no solvents or corrosive vapours while setting and sets quickly under all conditions when exposed to air. LN7 is compatible with all metals and plastics and contains no components that can degrade insulating glass seals. Conforms to BS EN 15651-1,2:2012.

USES

• Bond It LN7 can be used in construction, engineering and electrical applications. It is used as a high extensibility sealant for external and internal applications, including expansion joints, and perimeters of frames. As a rubber adhesive for bonding most materials. As a potting compound to encapsulate electronic components to protect from moisture, tampering and shock. As a gasketing material and as a bedding compound for glazing double glazed units into timber frames. LN7 is inherently resistant to fungal attack. Accelerated aging tests indicate a life expectancy of in excess of thirty years.
• It is ideal for use on:
• Glass
• Ceramics
• All metals
• Concrete
• Sealed timber
• Brick
• Most plastics
• Polycarbonate
• All painted surfaces.

APPLICATION INFORMATION

• Apply using a standard sealant gun with the nozzle cut at an angle of 45°, and to an opening slightly larger than the joint to be sealed. Best tooling is achieved if a minute or two is allowed after application before smoothing. Polyethylene foam backing rod pushed into construction joints before sealing gives a technically superior joint and minimises sealant consumption. For gaskets and potting applications ensure that the sealant has some contact with the air as total encapsulation of the sealant will prevent curing. Once the silicone has been applied and tooled rain will not have any adverse effects on the sealant.

SUBSTRATE PREPARATION

• Ensure all surfaces are clean, dry and free from grease, oil or any other contaminants that may hinder adhesion. On porous surfaces priming may be necessary.

LIMITATIONS

• Porous surfaces should be primed first. Do not use on surfaces where water can penetrate through porous materials to the bond interface without first carrying out remedial work. Polished decorative stone such as granite, etc may absorb silicone oil from the sealant and undergo a change in surface gloss. The safety backing on some mirrors is not suitable for adhesive fixing with silicone. If using mirrors with a safety backing ALWAYS carry out an adhesion test.
