Product descriptions:
Aplication:
1. For structural glazing in glass, glass roof and metal structure engineering.
2. Structural glazing in high risk glass curtain wall.
3. For the situation of high requirement to adhesive safety and other purpose.
Characteristics:
1. It is RTV-1, neutral curing at room temperature, high modulus and high intensity silicone structural sealant.
2. Excellent adhesion to most common building material without priming in general condition.
3. Excellent resistance to weather, low and high.
4. Good compatibility with other neutral silicone sealants.
Limitations:
1. Unsuitable for all kinds of material that can effuse grease, plasticizer or solvent.
2. Unsuitable for the airproof location, cause it is required to absorb moisture in air to cure for the silicone sealant.
3. Unsuitable for the frosty or moist surface
4. Unsuitable for the continually soggy or moist place.
5. Cannot be used if the surface temperature is below 4ºC or above 40ºC on the surface of the material.
6. Cannot be used if the surface is unclear or infirm.
Shelf life: 12 months from production date under the cool dry place at the temperature below 27ºC.
