Selsil Mirror Silicone – 310 ml Clear (Box of 25)
Selsil Mirror Silicone is a single-component, gun-applied, alkoxy-based neutral professional adhesive and sealant. Thanks to its neutral curing mechanism, it does not cause metal corrosion and provides secure adhesion without damaging the mirror coating. Its low-modulus and high-elasticity structure adapts to surface movements. Its fungicide content makes it resistant to mold. It meets ISO 11600 – F&G – 25 LM standards. This product is sold by the box containing 25 cartridges; it is ideal for wholesale purchase, workshop stock, and mass production.

Why is Special Silicone Required for Mirrors?
- Protects Mirror Coating: Acidic (acetoxy) silicones can damage the silver/nickel coating (backing) on the back of the mirror. The neutral alkoxy-based formula protects the coating layer.
- No Metal Corrosion: Does not cause rust or corrosion on mirror frames or mounting hardware.
- High Elasticity: Its low-modulus structure adapts to wall movements and vibrations, preventing mirror cracking.
- Primerless Adhesion: Shows strong adhesion to most surfaces without requiring a primer, reducing labor time.
- Fungicide Protection: Prevents mold formation in humid environments (bathrooms, kitchens).
Neutral vs Acetoxy Silicone: What is the Difference?
| Feature | Neutral (Alkoxy) Silicone | Acetoxy Silicone |
|---|---|---|
| Curing By-product | Alcohol (harmless, low odor) | Acetic acid (vinegar smell) |
| Metal Corrosion | None | Possible (on sensitive metals) |
| Mirror Compatibility | Yes (protects coating) | No (may damage coating) |
| Odor | Low odor | Sharp vinegar smell |
| Recommended Use | Mirror, sensitive metal, windows | General glass, ceramic, bathroom |
Usage Areas

- Window Sealing: Insulation of PVC, wood, and aluminum window edges
- Glass Structures: Showcase, glass box, and greenhouse glass assembly
- Multi-surface Bonding: Joining brick, metal, polycarbonate, and varnished wood
- Humid Environments: Mold-resistant filling in bathrooms, kitchens, and spa areas
Frequently Asked Questions
Does mirror silicone really not damage the mirror coating?
Yes. The alkoxy-based neutral formula does not contain acetic acid; therefore, it does not damage the silver/nickel coating (backing) on the back of the mirror. Acidic silicones can cause the coating layer to darken or peel over time.
On which surfaces does it adhere without a primer?
It shows strong adhesion to GLASS, mirror, aluminum, PVC, polycarbonate, varnished/painted wood, glazed ceramic, and brick surfaces without requiring a primer. For highly porous or oily surfaces, the use of a primer is recommended.
What is the curing time?
Surface drying occurs within 10–20 minutes. Full curing may take up to 24 hours depending on thickness and ambient humidity. It is recommended to wait at least 24 hours before applying a full load in mirror installation.
What does ISO 11600 – F&G – 25 LM mean?
This standard defines the performance of structural sealants. "F&G" refers to glass and general use, while "25 LM" means ±25% movement capability. This means the silicone can withstand expansion/contraction up to 25% at the joints.
How much area does a 310 ml cartridge cover?
310 ml of silicone creates a line approximately 12–15 meters long (5 mm in diameter). One cartridge is typically sufficient for an average bathroom mirror installation. Please plan the quantity according to the dimensions of your project.
