Description
The Pyrosil FB25 refill is a 50 g (1.76 oz) cartridge of propane and butane gas dosed with Pyrosil® precursor, made for the FB25 hand burner. Refilling the burner from it keeps you flame treating glass, ceramics, and metal before bonding, coating, or UV ink printing. SURA Instruments makes it in Germany.
It fits the FB25 only, and it is gas only, with no primer. The GVE2 HB unit uses 330 g cartridges. Need a burner and primer too? See the FB25 kit.

Performance in Production
- SURA lists about 45 minutes of service time per filling.
- Refill the burner only with original Pyrosil cartridges.
- The cartridge fits the FB25 only. The GVE2 HB runs on 330 g cartridges.
- Metal, glass, and ceramics need 6 to 12 flame passes. Test a sample to set your own pass count.
- Keep primer on hand. SURA recommends priming within 30 minutes of treatment, and 12 hours at most.
- Pyrosil gas forms explosive mixtures with air. Remove ignition sources, don’t smoke, and ventilate for longer work.
Common Applications
- Flame treatment before UV ink and digital ink printing on glass and metal parts

How Pyrosil Flame Treatment Works
Pyrosil treatment is combustion chemical vapor deposition (CCVD). The precursor in the cartridge burns in the flame to silicon dioxide, a layer 5 to 100 nanometers thick that deposits on the part and gives primers, inks, adhesives, and coatings a surface they bond to. A filling of the FB25 goes like this:
Water spreads on the Pyrosil-labeled panel and beads on the other panel.
- Refill the burner only with an original Pyrosil cartridge.
- Start with a clean, dry part. Warm metal, glass, and ceramics to 104 to 122 °F (40 to 50 °C).
- Light the burner and treat with the non-luminous (oxidizing) part of the flame. Move it gently up and down the surface, 6 to 12 passes on metal, glass, and ceramics.
- Plan on about 45 minutes of service time per filling.
- Within 30 minutes (12 hours maximum), apply a SurALink primer, then print or bond.
Frequently Asked Questions
What is the Pyrosil FB25 refill cartridge?
It is the gas cartridge for the FB25 hand burner. Each 50 g (1.76 oz) cartridge holds a propane and butane mix with Pyrosil precursor, and the burner is refilled from it. SURA calls the FB25 a hand burner, and many shops call it a torch.
Does this refill fit the GVE2 HB?
No. This cartridge is for the FB25 hand burner only. The GVE2 HB uses 330 g Pyrosil cartridges, the P2 for plastics or an MGK cartridge for metal, glass, and ceramic. Call us if you’re not sure which one your unit takes.
How long does one refill last?
SURA lists about 45 minutes of service time per filling, and AST lists about 50 sq ft of coverage per cartridge. Your parts per filling depend on material and pass count, so run a sample to set it.
Can I fill the FB25 with another gas?
No. SURA says the burner should be filled only with original Pyrosil cartridges.
Does the refill include primer?
No. The cartridge is gas only. The FB25 kit includes SurALink 011, which AST describes for acrylate coatings and adhesives and digital ink. AST lists SurALink 021 for epoxy and polyester coatings and adhesion with epoxy resin. Call us for primers.
How long can I wait between treatment and priming or bonding?
SURA recommends following up within 30 minutes, and no later than 12 hours. SURA says the surface activation itself lasts several weeks in dry air at 72 to 77 °F (22 to 25 °C).
Which materials can the FB25 treat?
SURA lists glass, ceramic, and metal for the FB25’s cartridge. For plastic parts, SURA’s plastic cartridge is the P2 for the GVE2 HB, so call us with your material before you buy. Use caution with PTFE and other fluorine-containing polymers.
Is the Pyrosil cartridge safe to handle and ship?
Handle it like any propane and butane product. Pyrosil forms explosive mixtures with air, so remove ignition sources and don’t smoke. SURA says the process forms no toxic or harmful reaction products, and recommends good aeration or an exhaust for longer work. The cartridge ships as a hazmat product.
