Acetoxy Silicone vs. Neutral Cure Silicone: Know the Difference
By Shumaila Saeed || Published on January 12, 2024
Acetoxy silicone cures with acetic acid byproducts and has a strong vinegar smell, while neutral cure silicone releases no odor and is more versatile.
Key Differences
Acetoxy silicone cures by releasing acetic acid, resulting in a vinegar-like smell, indicating its curing process. Neutral cure silicone, however, cures without emitting strong odors, making it more suitable for enclosed spaces.
