Product Details

This is a high-strength, high-elasticity, single-component polyurethane adhesive specifically designed for outdoor track systems, offering exceptional weather resistance. It is typically available in solvent-based or solvent-free formulations to provide superior water resistance, curing speed, and ultimate strength compared to water-based adhesives. Its core function is to firmly bond EPDM rubber granules together and adhere them to the base layer, forming a stable, resilient track surface.

Parameter	Description
Appearance	Typically a black or gray viscous liquid, designed to blend with EPDM granule colors for a seamless look.
Solid Content	≥ 40% - 60% (by weight). A higher solid content generally correlates with higher bond strength and lower shrinkage.
Viscosity	High (often measured in thousands or tens of thousands of cps using a Brookfield viscometer). This ensures it can "hold" heavy rubber granules without excessive flow.
Open Time	Relatively short, approx. 10-20 minutes. This refers to the window for applying granules after the adhesive is laid. Wind and sun exposure can shorten this time, requiring skilled application.
Initial Cure Time	Approx. 2-4 hours (at 25°C). The surface can be walked on for next steps after this time.
Full Cure Time	Approx. 24-72 hours (dependent on temperature and humidity). Final strength is achieved after full cure.
Tensile Strength	> 1.5 MPa (bond strength to cement concrete base). This value is crucial to ensure granules are locked firmly in place.
Elastic Recovery	> 90%. A critical metric for track adhesives, ensuring the surface rebounds after impact, providing energy return and joint protection.
Weather Resistance	Must pass accelerated weathering tests (e.g., QUV test) to guarantee long-term resistance to sun, rain, and temperature cycles without delamination, cracking, or powdering.
