Which standard does GP131 Aquarium Silicone Sealant meet?

The GP131 follows the standard of 1 G GB 16776-2005 which is the high standard for sealant performance.


Why the requirement for Aquarium Silicone Sealant is the strictest?

Reducing the possibility of break:

Usually, the large fish tank has high pressure. Using the quality aquarium silicone sealant is necessary which can reduce the possibility of breaking.



The fish tank usually uses UV lights to kill microorganisms and bacteria to provide a better environment for fish. Thus, one of the significant abilities of aquarium silicone sealants is yellowing resistance and durability. If the users used a sealant that does not conform to the standard, the possibility of redecoration will be higher.

The 1 G GB 16776 has ruled the tensile adhesion ability in different temperatures, UV light and immersion in water. In long term UV light and after immersion in water, it regulated the sealant’s tensile adhesion ability must be large than 0.45 MPa.


Long-life working:

The sealant used in the aquarium is not possible to redecoration frequently. Thus, we must choose a 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 aquariums 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 persons 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.


Curing Time:

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.
