What it is
MCP Polyols & Binders is the broader catalog of MCPU base polyurethane chemistry: custom polyether and polyester polyols, the MCP 3335 electronics encapsulant, the Iron Sentry® fluid-applied roof coating system, and one-component moisture-cure binders for rubber-crumb athletic surfaces and playground safety surfacing.
Key benefits
- Custom polyols engineered to your equivalent weight, functionality, and viscosity targets.
- MCP 3335 encapsulant: low-exotherm, low-shrink potting for Fortune-500 filtration assemblies.
- Iron Sentry® roof coating: fluid-applied, fully-adhered, walkable membrane.
- Moisture-cure rubber binders: outdoor-stable, UV-resistant, ADA-compliant safety surfacing.
How it works (chemistry overview)
Each MCP system is built from base diisocyanate and polyol building blocks selected for the end-use environment — aliphatic isocyanates for UV-stable outdoor coatings, MDI prepolymers for toughened binders, and tightly-controlled equivalent-weight polyethers for low-exotherm encapsulation.
Applications
- Electronics & filtration potting (MCP 3335)
- Commercial fluid-applied roof restoration (Iron Sentry®)
- Athletic tracks, playgrounds, and safety surfaces (rubber-crumb binders)
- Custom CASE polyols for OEM formulators
Sustainability profile
Low-VOC and 1K moisture-cure options; long-life roofing reduces tear-off waste; recycled-rubber binders divert tire crumb from landfill.
