Single-Component Spray Coating Adhesive

State: Viscous liquid (customizable colors: red, green, blue, etc.)

Main Chemical Composition: Isocyanate-terminated prepolymer

Viscosity (25°C, mPa·s): 7,000–9,000; moderate fluidity with superior atomization effect

Packaging Specification: 25kg per barrel

1.Convenient and efficient construction: Single-component design ready for use straight from the barrel, eliminating on-site proportioning. It resolves common pain points of two-component adhesives including uneven mixing and premature gelation, greatly reducing operational complexity.

2.Solvent-free and eco-friendly, fully compliant: Zero-solvent system with ultra-low VOC content and no harsh construction odors, meeting environmental safety standards for schools and public sports venues.

3.Fast curing and short construction cycle: Unique quick-dry formulation shortens project timelines, reduces venue closure duration, cuts material consumption and overall project costs.

4.Superior weather resistance and long-lasting color: Excellent compatibility with EPDM granules. The cured surface resists UV radiation and aging, retaining vibrant color long-term without chalking or peeling.

5.Ultra-strong bonding for stable structure: Exceptional encapsulation and adhesion to colored EPDM granules, solving common quality defects such as surface granule shedding and delamination to extend venue service life.

6.Cost-effective: Delivers premium physical performance and easy construction at an affordable price, the economical top choice for surface treatment of permeable and mixed-type tracks.

This product is a blend of pigment and adhesive; raw material costs vary slightly across colors (e.g., deep red, emerald green).

Curing speed is heavily affected by ambient temperature. Control spray thickness in hot weather to prevent sagging.

Surface spray sealing for permeable and mixed-type plastic tracks

Anti-slip and aesthetic finishing for full-PU track surfaces

Color surfacing and renovation for kindergarten and community fitness walkways

Renovation and recoloring of aged plastic sports venues

1.Urban park walkway renovation project: Blue single-component spray coating adhesive covered aged black walkways. Fast construction allowed venue reopening within 24 hours with consistent bright color and minimal fading.

2.Primary and secondary school plastic playground surface treatment: Green spray coating sealed the track surface, eliminating loose surface granules and passing acceptance inspections on the first attempt. The school commended its low odor and attractive appearance.

Q1: Will single-component spray coating adhesive lack durability? 

A: No concerns. Despite its single-component design, high-activity isocyanate-terminated prepolymer delivers dense crosslinking after curing. Its tensile strength and wear resistance outperform standard two-component surface adhesives while eliminating bubbling or incomplete curing risks from inaccurate proportioning.

Q2: Is viscosity of 7,000–9,000 mPa·s suitable for spraying? 

A: This viscosity range is optimized for spraying. Too low viscosity causes sagging; too high viscosity clogs spray guns. This golden viscosity achieves uniform, fine atomization with standard spray equipment for full encapsulation of EPDM granules.

Q3: Can it be used as a base coat? 

A: Formulated exclusively for surface coats. While bonding strength is high, its core performance advantages lie in surface wear resistance and UV resistance. Use dedicated base coat adhesive (e.g., No.06 general type) for base layers and this product for surface coats for optimal cost-performance.

Q4: Will the color fade? 

A: High-concentration weather-resistant color paste is dispersed via specialized processes with strong color penetration. Color fades gradually with natural adhesive aging under regular use; patchy discoloration will not occur.
