Neutral silicone is a moisture-curing silicone sealant that releases no acid during cure (alkoxy or oxime systems), so it can be used on metal, concrete, stone, mirrors and many plastics without corrosion or staining. Excellent UV and weather resistance make it the standard for façades and glazing.
| Property | Neutral | Acetic |
|---|---|---|
| By-product | Alcohol/oxime | Acetic acid |
| Metal & concrete | Suitable | Risk of corrosion/staining |
| Odour | Low | Strong (vinegar) |
Choose low-modulus grades for façade joints, non-staining grades for natural stone and mirror-compatible grades for mirrors. Silicone cannot be painted — use PU or acrylic sealant where painting is needed.
