A binder is invisible when it works. Athletic tracks, playground safety surfacing and poured rubber flooring live outdoors under UV, standing water and constant mechanical abuse, and the binder is what holds the crumb together through all of it.
MCPU supplies one-component moisture-cure binders built for that exposure, plus the surfacing support to hit impact attenuation requirements.
What this application has to hit
- UV stability without ambering or surface chalking
- Impact attenuation for ADA-compliant playground safety surfacing
- Wet and freeze-thaw durability with reliable crumb adhesion
- Single-component application practical for field crews
- Recycled-content compatibility with tire crumb and EPDM
How MCPU formulates for it
One-component moisture-cure chemistry lets field crews install without metering equipment while still developing a tough, fully-cured network.
Aliphatic backbone selection keeps the installed surface color-stable through years of direct sun.
Binder modulus and elongation are tuned to hold the crumb while preserving the compliance that impact attenuation testing requires.
Formulation levers we adjust
| Lever | What it controls |
|---|---|
| Cure route | 1K moisture-cure for field practicality; 2K where throughput allows. |
| Backbone | Aliphatic chemistry for outdoor color stability. |
| Modulus | Balanced against impact attenuation and crumb retention. |
| Wet-out | Viscosity set for full coating of crumb at mix ratio. |
