Both the 1100SL and 1150FC epoxy adhesives have the same mix ratios, solids content, mixed viscosity, and VOC content, so choosing between the two comes down to examining their differences.
While both products provide industrial-grade structural performance suitable for heavy-duty flooring systems, SIMIRON 1100SL self-leveling epoxy offers slightly higher compressive and tensile strength. It also has a wide range of working times available because of its fast, slow, and standard cure speed formulations.
On the other hand, the 1150FC from SIMIRON only has a fast cure speed option but has the added benefits of being able to be applied at lower temperatures and having excellent blush resistance. The technical datasheet of the SIMIRON 1150FC fast cure epoxy also mentions a resistance to moisture vapor transmission up to 12 lbs. There is no mention of this property for SIMIRON 1100SL.
Ideal Uses
While the two materials are similar in a lot of ways and are recommended overall for use in epoxy floor coating applications, their strengths lead to slightly different ideal use cases.
The SIMIRON 1100SL epoxy floor coating may be best used for the following scenarios:
- Flexible cure scheduling
- Larger floor areas that require extended working time
- General application temperatures
- Decorative broadcast systems such as chip, quartz, or metallic floors
Because of its multiple cure speeds, 1100SL works well when you need scheduling flexibility. You can select a slower formula for larger pours or a faster option when turnaround time matters. This flexibility allows you to match pot life to crew size and layout complexity. In the end, you can reduce material waste and installation stress. For contractors managing multi-phase projects or detailed decorative work, this added control can make a measurable difference in efficiency.
Compared to the SIMIRON 1100SL floor coating, the SIMIRON 1150FC may be a better choice for the following scenarios:
