The Difference Between Acetoxy Silicone Sealants and Neutral Silicone Sealant

There are two main types of one-part silicone sealant: acetoxy curing silicone sealant and neutral curing silicone sealant.

The Characteristics of Acetic Silicone SealantIMG_3585.jpg

Acetic silicone sealant gets its name from the fact that it releases acetic acid as it cures. It dries faster than most other silicone sealants. It also adheres well to a wide range of construction materials, particularly glass adhesives.


- It has the shortest cure time of the three systems.- Excellent weather resistance: resistant to ozone and UV rays.


- Strong pungent odour during application and cure period.

- Producing a caustic by-product


- Commonly used in building sealing and bonding, glass assembly, sink caulking and sealing, and other similar applications.

The Characteristics of Neutral Silicone SealantIMG_8084.jpg

The oxime curing and alkoxy curing are included in the neutral silicone sealant. In contrast to the acetoxy silicone sealant, the oxime silicone sealant emits methyl ethyl ketoxime, and the alkoxy silicone emits alcohol. 


- The properties of neutral silicone sealant are compatible with a wide range of materials, including glass, ceramics, tiles, metal, PVC, electronic appliances, auto and so on. - The quality neutral silicone is compatible with other neutral silicones well.


- Curing time is longer than for acetoxy silicone sealant.

To summarize, I have mentioned the advantages and disadvantages of three main types of curing systems below:

Type of Silicone Sealant3 Main Curing Systems
Acetoxy Silicone SealantAcetoxy CuringAcetic Acid

- Good adhesion stable ≤300°C

- Fast Cure

- Corrosive

- Pungent Odor

Neutral Silicone Sealant

Oxime CuringMethylethylketoxime- Good Adhesions to plastics

- Low Corrosive

- Health & Safety Problem

- Low exposure levels

Alkoxy CuringAlcohol

- Good Adhesion to various substrates

- Non-corrosive

- Slow Cure

- Sensitive to the storage environment

Since 1993, Haohong New Materials has concentrated on silicone sealant research. Acetic silicones, alkoxy silicones, and oxime silicones are among the silicone sealant products we offer. Furthermore, the 16-set fully automated silicone sealant production line includes all silicone sealant varieties. It motivates Haohong to supply high-quality items to our customers.

Haohong hoping to provide excellent sealants, and seal us together!
