Features:
1.N669 Single-component, neutral-based, room temperature curing, high performance structural silicone sealant, can easily be constructed out of and in the air react with water, curing into a no corrosion elastomers with the resistance cold and heat.
2. With resistance to ozone, UV-resistant properties such as superior resistance to weather, given its long life.
3. Has good adhesion, without primer under normal conditions. After curing for most building materials, such as glass, aluminum, steel and stone and other surfaces can produce good adhesion.

Main use:
1. For the structural bonding of glass curtain wall assembly, it will be glass and metal components directly connected constitute a single assembly component surface to meet the fully implicit or semi-hidden frame curtain wall design requirements.
2. Hollow glass structural adhesive seal.

Construction requirements:
1. Before using the N691, you must first contact the material compatibility and adhesion test, confirm qualified to be constructed after the operation.
2. Construction materials in contact with the adhesive surface of the structure may not have water, dust, oil materials exist, or must be cleaned with toluene or acetone, and kept dry;
3. To ensure a perfect line of silicone rubber around the clean area near the interface can be covered with tape, but the tape must not touch the surface of the structure will be the construction, repair work is completed shall immediately clear the cover tape.

Storage period:
Should be stored in a cool dry place, storage temperature should be lower than 27 ℃, storage period of 9 months.
Meet the national standard: GB16776-2005
