Difference Between Acidic Silicone Sealant And Neutral Silicone Sealant

Differences in principle

1. Acidic silicone sealant

Releases acetic acid (with a pungent odor) during curing.

Composed primarily of an acetic acid crosslinker (such as methyltriacetoxysilane).

Suitable for bonding glass and some metal surfaces, but may be corrosive to materials like concrete and marble.

2. Neutral silicone sealant

Releases alcohols or ketoximes during curing and has no strong odor.

Composed primarily of an alcohol or oxime crosslinker (such as methyltributyketoximesilane).

Provides better adhesion to a variety of substrates (glass, metal, stone, plastic, etc.) and offers superior weather resistance compared to acidic silicone sealant.

Differences in silicone sealant production line equipment configuration

1. Acidic silicone sealant production line

Triple shaft mixer + vacuum system + filler

Low investment cost, simple process.

2. Neutral silicone sealant production line

Triple shaft mixer + high-sealing vacuum system + automatic dosing + filler

Higher investment cost, but greater product added value and market demand.

Production Line Process Differences

For entry-level investment: JCT recommend acidic silicone sealant production line, which requires minimal equipment investment and is relatively simple to operate.

For the high-end market: JCT recommend neutral silicone sealant production line, which offers superior weather resistance, a wider range of applications, and higher added value.
