Acidic Silicone Sealant vs Neutral Silicone Sealant
| Different | Acidic Silicone Sealant | Neutral Silicone Sealant |
|---|---|---|
|
Chemical Properties |
Acidic silicone sealant is composed of impurities such as polysiloxane and acid catalyst, which makes it somewhat acidic. | Neutral silicone sealant is composed of impurities such as polysiloxane and aminosilane and will not produce acid-base reactions. |
| Application | Mainly used in fields such as construction and the automotive industry, such as sealing kitchens and bathrooms, waterproofing and protecting joints. In addition, acidic silicone sealant also performs well in some extreme environments, such as high temperature and humid environments. | Mainly used in fields such as construction installation, home renovation, glass craftsmanship and electronic industry, such as sealing doors and windows, fixing glass and electronic components. Due to its neutral properties, neutral silicone sealant has a wider range of applications. |
| Advantage | Acidic silicone sealant can perform good sealing and bonding in high temperature and humid environments. | Neutral silicone sealant has good insulation and can effectively bond and seal hard materials. |
| Disadvantages | Due to the acidic nature of acidic silicone sealant, it cannot be used for bonding alkaline materials such as metal, glass and ceramics. In addition, when using it, you need to pay attention to the silicone sealant being applied inside the area and not touching human skin and eyes. | Neutral silicone sealant has a slow bonding speed and requires a period of time before bonding is successful. In addition, its high temperature resistance is not as good as acidic silicone sealant. |
