Heavy-Duty Polyurethane Gravel Binder – UV Stable PU Resin for Outdoor Aggregate Bonding

100% Aliphatic Chemistry|Elastic Polymer Matrix|Lower TCO|Workable Pot Life

Substandard binders often fail under severe UV, ground shifting, and heavy traffic, causing yellowing and cracking that lead to costly callbacks and unbilled rework. Jincheng Polyurethane Gravel Binder provides contractors and specifiers with a reliable two-part system engineered to protect job-site profit margins:

100% Aliphatic Chemistry: Delivers complete UV resistance to prevent stone discoloration, keeping clear coats clear and eliminating post-installation client disputes.
Elastic Polymer Matrix: Cures into a flexible, high-tensile bond that absorbs ground movement and thermal expansion, stopping surface cracking and stone popping even in freeze-thaw zones.
Workable Pot Life: Offers a stable working window across various site conditions for easy aggregate coating, helping crews maintain pace and hit inspection sign-offs on schedule.

Ideal for municipal plazas, commercial real estate, and permeable SuDS paving.

Bad Resin Choice Will Kill Your Profit Margin on Landscape Job Sites

Ask any contractor: nothing eats up profits faster than a resin driveway turning yellow or cracking six months after sign-off. Between subgrade movement, heavy foot traffic, and harsh sun, cheap binders fail quickly. That means unpaid rework, angry clients, and endless warranty calls.

We built Jincheng Polyurethane Gravel Binder specifically to stop those callbacks. It’s a heavy-duty, two-part aliphatic polyurethane system engineered for real-world resin-bound aggregate installations.

Key Technical Perks:

Pure Aliphatic Base (Stop Solar Discoloration): Standard aromatic binders break down in UV light. They’ll take a nice light quartz mix and turn it muddy amber within a season. Jincheng uses 100% aliphatic chemistry so the clear coat stays clear. Natural stone colors stay sharp, and you don’t end up arguing with property owners over discolored driveways.
Elastic Polymer Matrix (Prevents Cracking & Loss of Stone)

Brittle resins crack when ground conditions move. Jincheng’s matrix cures into a flexible yet high-tensile bond that flexing with micro-settlement, ground movement, and thermal expansion. This elasticity stops surface cracking, stone popping, and edge raveling, even in freeze-thaw zones or under heavy pedestrian loads.

Project Execution & Commercial Impact

Reduced Lifetime Maintenance (Lower TCO)

For commercial property managers, a cheap initial material price often leads to expensive ongoing repairs. Jincheng holds up against traffic wear, standing water, and extreme temperature swings, cutting long-term repair cycles and protecting total cost of ownership.
Workable Pot Life for On-Time Handover

Field crews need predictable set times. The resin formula provides a stable working window across different humidity levels and ambient temperatures. It coats washed natural gravel and aggregates cleanly without clumping, helping crews lay square footage quickly and hit inspection sign-offs on schedule.

Recommended Applications

Jincheng two-component Polyurethane Gravel Binder is regularly specified for:

Civic & Municipal: Public plazas, park greenways, boardwalks, and urban walkways.
Commercial Real Estate: Hotel courtyards, open-air retail centers, and residential developments.
Permeable Paving (SuDS / Sustainable Urban Drainage): Porous tree pit surrounds, eco-paths, and sustainable drainage surfaces.

Construction method: Scraper Construction description: The mixture ratio of materials and adhesives, A:B=2:1 (weight ratio). Stirred adhesive: rice stone =1:25 (weight ratio); According to the construction mixture ratio, the materials in equal proportion are mixed and stirred evenly (the mixing time of adhesive AB is 2-3 minutes, and the mixing time of stones and adhesives is 3-5 minutes. A mixing amount should ensure that the construction is completed in 30 minutes at room temperature)

COVERAGE RATES: The coverage of this product depends on the thickness ofthe application,for pedestrian traffic we advise a l5mm thickness, for vehicle traffic we recommend an 18mm thickness.

Pedestrian Traffic: Each 7kg kit will cover 4.05m2 at 15mm on average.

Vehicle Traffic: Each 7kg kit will cover 3.55m2 at 18mm on average.
