Special Silicon PU Materials for Courts

1.Single-component design with stable storage: Eliminates errors from A/B proportioning to prevent site bubbling or incomplete curing. Simply stir evenly after opening for construction.

2.Superior physical performance with balanced elasticity: 2.0 MPa tensile strength and 205% elongation deliver outstanding shock absorption and tear resistance, cushioning sports impacts to protect athletes’ joints.

3.Excellent leveling for premium aesthetics: Fluidity automatically fills minor base pores, forming a smooth, glossy cured surface free of joint marks to elevate overall court quality.

4.High gum content for long service life: High-solid formulation creates dense, wear-resistant film that resists peeling and delamination under frequent heavy use.

5.Easy construction with high tolerance: Low technical requirements for workers; smooth scraping without bubbling or sticking tools, suitable for elastic and reinforcement layers of basketball, tennis and badminton courts.

6.Cost-effective: Professional sports performance at reduced material and construction costs, the top choice for school and community court construction.

High viscosity (10,000–12,000 mPa·s) requires extended stirring time or limited addition of dedicated thinner for good leveling when constructing below 10°C.

Elastic layer construction for basketball, tennis, badminton and other ball courts

Partial repair and reinforcement layer treatment for plastic tracks

Indoor and outdoor sports flooring requiring high elasticity and wear resistance

1.Community basketball court renovation project: Single-component silicon PU formed the court elastic layer. Easy construction and excellent leveling delivered superior rebound performance; residents praised comfortable ball feel without rigid texture.

2.Indoor school gymnasium badminton courts: Eco-friendly low-odor silicon PU was selected for indoor construction with fast turnaround, solving issues of poor ventilation and tight construction schedules.

Q1: What is the difference between single-component silicon PU and traditional two-component silicon PU? 

A: The core difference lies in construction convenience. Single-component eliminates proportioning errors that can render entire venues unusable, with more stable storage. While two-component products offer higher reaction activity, modified technology matches full performance of two-component variants with higher construction tolerance.

Q2: Is 2.0 MPa tensile strength sufficient? 

A: More than sufficient. This index meets and exceeds national standard requirements for court elastic layers. Excessively high strength creates rigid surfaces with poor foot feel; 2.0 MPa paired with 205% elongation achieves ideal balance of athlete protection and ball rebound rate.

Q3: Can water be used for dilution? 

A: Water dilution is strictly prohibited. Use only manufacturer-provided dedicated thinner if viscosity adjustment is needed, with maximum addition of 5% to avoid compromising curing performance and environmental indicators.
