Which standard does NP122 Weatherproof Silicone Sealant meet?
The NP122 follows the standard of GB/T14683-2017 which is the high standard for weatherproof silicone sealant performance.
Why the requirement for Silicone Sealant is the strictest?
Reducing the possibility of break:
Usually, the sealing and caulking of various substrates. The quality of silicone sealant determines the life working of substrates directly. The sealant 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 GB/T14683-2017 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 larger than 0.4 MPa.
The sealant is used in home decoration, industrial purposes, and so on. Thus, it is not possible to redecoration frequently. Thus, we must choose a quality silicone sealant, which decreases the possibility of refurbishment. The GB/T 14683-2017 has an anti-aging test, which ensures whether the sealant can be used for long working life. Reducing the possibility of refurbishment.
All Haohong’s sealants conform to the standard of GB/T14683-2017. Thus, our technical staffs recommend users used 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, and even change color.
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.
