Tubeless sealant with or without ammonia: Why your choice defines the life of your tire?
Tubeless tires have been the biggest revolution in mountain biking, road cycling, and gravel biking in the last decade. However, not all sealant is created equal. While some focus solely on sealing the puncture, others, like Damoff Sealant , are also designed to protect the most expensive component of your wheel: the rim.
In this article, we explain why ammonia is the silent enemy of your bicycle and how to choose the best sealant for 2025.
The hidden danger: Galvanic corrosion
Many inexpensive sealants on the market use ammonia as a stabilizer to keep the liquid latex contained in the bottle. The problem arises when this chemical comes into contact with the aluminum of the rim or even the spoke nipples.
- Attack on aluminum: Ammonia accelerates oxidation, creating small pits on the inner surface of the rim.
- Damage to the rim bottom: This can weaken the adhesive of the tubeless tape, causing unexplained air leaks.
- Lifespan: A tire that should last for years can become unusable in a couple of seasons due to the use of aggressive sealants.
The Damoff solution: Our formula is 100% ammonia-free . It's completely neutral, guaranteeing that even if the fluid remains in the wheel for months, your components will stay like new.
Technical Comparison: Damoff Sealant vs. Conventional Sealants
| Feature | Standard Sealant | Damoff Sealant (2025) |
| Chemical Basis | With Ammonia (Aggressive) | Ammonia-free (Safe) |
| Sealing capacity | 2-3 mm holes | Up to 8 mm (XL Particles) |
| CO2 compatibility | It solidifies / Creates balls | Compatible (Does not freeze) |
| Liquid Duration | 2-3 months | 4-6 months (High stability) |
| Waste | Difficult to clean | Easy to clean with water |
The key factor: Compatibility with CO2 cylinders
Many cyclists are unaware that, in an emergency, using a CO2 cartridge can ruin their tire sealant. The extreme cold of the gas often freezes or "cuts" low-quality latex, creating a solid ball inside the tire that no longer seals.
Damoff Sealant is formulated to withstand sudden temperature changes. If you get a large puncture and need to use CO2 to quickly seat the tire, our sealant will still be effective in sealing the hole and getting you home.
If you invest in quality wheels, don't skimp on the sealant. Damoff Sealant not only saves you from walking miles with your bike on your shoulder thanks to its sealing capacity of up to 8mm, but it also acts as a lifeline for your rims.
3 Maintenance Tips for an "Always On" Tubeless Tire
For the system to be 100% reliable, it is not enough to use the best product; you have to know how to maintain it:
- Check the level every 3-4 months: In warm climates, the fluid tends to evaporate faster. Don't wait until you get a puncture to find out you're dry.
- Clean the valve core: If you notice that it's difficult to inflate the tire, the latex has probably clogged the valve. Remove it and clean it with hot water.
- Shake well before use: Damoff's sealing particles are dense enough to plug large holes; make sure to shake the can well to ensure they are evenly distributed before refilling.
