Which standard does NP121 Aquarium Silicone Sealant meet?
The NP121 follows the standard of 1 G GB 16776-2005 which is the high standard for structural silicone sealant performance.
Why the requirement for Aquarium Silicone Sealant is the strictest?
Reducing the possibility of break:
Usually, the quality of silicone sealant is one of the important factors for the façade and large windows assembly. The façade assembly has high pressure. Thus, the quality of structural silicone sealant is necessary which can reduce the possibility of breaking.
Usually, the structural silicone sealant is used for interior and exterior façades and windows. Thus, one of the significant abilities of structural silicone sealant is weather resistance, discolouration, and durability. If the users used a sealant that does not conform to the standard, the possibility of redecoration will be higher. Even, using the defective products would be increasing the possibility of safety problems.
The 1 G GB 16776 has ruled the tensile adhesion ability in different temperatures, weather variety and immersion in the rain. In long term weather variety and immersion in water, it regulated the sealant’s tensile adhesion ability must be large than 0.45MPa.
The NP121 sealant used in the façade, curtain walls, and large windows is not possible to redecoration frequently, especially for outdoor use. Thus, we must choose quality silicone sealant, which decreases the possibility of refurbishment. The 1 G GB 16776 has an anti-aging test, which ensures whether the sealant can be used for long working life. Reducing the possibility of refurbishment.
There are many reasons that encourage users to use quality structural silicone sealant. Thus, we recommend the company use the products which conform to the standards.
Acetic Silicone Sealant VS Neutral Silicone Sealant
Recently, the acetic cured and neutral cured silicone sealants have been widely used in the construction and decoration industry. But many people are still not clear about the difference between acetic curing and neutral curing.
The smell of acetic silicone sealant is greater than the neutral silicone sealant.
The main purposes of acetic and neutral silicone sealants are different. Most building materials can be sealed by a neutral silicone sealant, and the sealant will not corrode the materials. Furthermore, the acetic silicone sealant is the most suitable for glass bonding. If we used the acid silicone sealant in metal, that may lead to corrosion of the materials, even change colour.
The curing time of acetic silicone sealant is the fastest. The Tack-Free time is about 5 to 15 minutes, which is convenient for the construction process. Usually, the curing time of a neutral silicone sealant is slower than the acetic silicone sealant.
