Why do colored road signs hold more ground after a heavy rain? Unveiling the secrets of a new road safety "armor"!

Release time：

2025-07-11

A torrential downpour swept through the city, leaving roads flooded.

While people were worried about damage to road markings, our company's "Color Road" brand preformed signs, after the downpour, remarkably held their vibrant color, maintaining its sharp lines and remaining motionless. This remarkable feat was the first real-world demonstration of the "golden partnership" of spray-painted color landmarks and a new, environmentally friendly water-based primer. Not only did they withstand the rigors of extreme weather, they also delivered a stunning performance in the preformed color speed limit sign application.

Unscathed by heavy rain? The secret lies in the "base"!

Traditional preformed reflective signs use standard primers, which can easily peel off in heavy rain. Our company has dedicated significant research and development to developing a new, environmentally friendly, water-based, and cost-effective primer. This core technology addresses two key challenges:

1. Strong adhesion, impervious to rain: Utilizing water-based polymer modification technology, nano-level penetration creates a "molecular grip" with the road surface. Testing revealed excellent adhesion even after prolonged exposure to heavy rain. Field tests showed that even after forcibly tearing the sign and reattaching it to the ground, it remained stable.

2. Green and safe, worry-free installation: The water-based formula eliminates the addition of hazardous chemicals, resulting in a pungent odor-free application. No special qualifications are required for transportation and storage, safeguarding both worker health and the community environment.

Preformed Signs + Eco-Friendly Primer: A "Smart Color" for Urban Roads

During field testing, we combined this primer with preformed color speed limit signs, and the results were astonishing:

Instantly Eye-Catching: The highly saturated color marks are clearly visible upon application and can be affixed to the ground during construction, significantly reducing road closure times.

Durable: The special flexible material is resistant to rolling and abrasion, and the strong adhesion of the primer effectively withstands repeated impacts from traffic.

Intelligent Empowerment: Vibrant colors and intuitive graphics significantly enhance driver visual perception, providing a "gentle yet firm" technological aid for speed limit management on critical roads.

Ensure that every road marking is weatherproof and provides clear and safe guidance for every trip. We look forward to collaborating with more city managers and partners to leverage technological innovation to create a smart, safe, and green future for transportation!
