XL Range
XL products come in large volumes: 400 ml cartridges, 1.7 L bottles or 10.2 L cans.
Although they share the same naming convention as products in the standard Fluid range, they are entirely different products, with different polymerization times, removal constraints, and other characteristics.
XL products take longer to polymerize, like the Long Polymerization (LP) products. You apply them with a 400 ml dispensing gun and a nozzle, or you mix them by hand.
Packaging Sizes
| Size | Format | Typical Use |
|---|---|---|
| 400 ml cartridge | Two-component cartridge for a dispensing gun | Large single impressions, series of impressions |
| 1.7 L bottle | Two bottles (2 x 850 ml), base and catalyst | Manual mixing, large volumes to reproduce |
| 10.2 L can | Two cans (2 x 5.1 L), base and catalyst | Production scale, protections, large fixtures |
All XL products are Fluid consistency. There are no Pasty or Manual Putty products in the XL range.
When to Use XL
- Large internal impressions. Bores above 50 mm diameter or deep cavities where you would need several 50 ml cartridges per impression.
- Protections. Reusable masks or fixtures for several parts. The larger volume lets you cover an entire assembly in one go.
- Extended working time. XL products polymerize more slowly than the standard products, giving you extra time to position and flow the material.
Differences from Standard Products
- 01 / 03
Longer polymerization time
20 minutes or more at 23°C. Larger volumes are harder to mix and apply, so they need more handling time. - 02 / 03
Same precision
The micron resolution and the absence of shrinkage are the same as for the standard products. - 03 / 03
Same selection logic
You still choose by consistency, hardness, and removal constraint.
Mixing XL Products
A 400 ml cartridge works like a 50 ml one. You need a 400 ml dispensing gun, DM-400 or DB-400, and a long nozzle that mixes the product.
Bottles and cans are mixed by hand, until the color is uniform.
- 400 ml cartridges. The nozzle mixes the two components at a 1:1 ratio.
- Bottles and bulk containers. Measure equal volumes of base and catalyst in a clean container, then mix them with a spatula for 30 seconds at most.
Cans must be stirred before each use, to homogenize each component. You need two XL Mixers, one for each component.
- Mix each component individually for 30 seconds, from bottom to top.
- Once done, clean the XL Mixer with “Essence F” or any equivalent.
- Never use the same XL Mixer for both components, even after cleaning it.
- Once both components are stirred, measure and mix them as described above.
Application Tips
Pour the material from the lowest point and allow it to rise naturally to minimize trapped air. Your nozzle must always stay in contact with the surface of the part.
Take your time. Air bubbles are harder to eliminate in a large volume.
Prepare your extraction method before applying the product. XL impressions are tough, so the force required to extract them is significant. If you do not have a grip wide enough or sufficient pulling force, you risk leaving the impression stuck inside the part.
A common workaround is to leave a void in the center of the impression to make deformation and extraction easier.
