TWO COMPONENTS PU ANTISKID COATING FOR ROAD

Colored Two-component Polyurethane Anti-slip Coating for Road

Product Description

It is environmental two-component polyurethane adhesive material.

Colored and suitable for anti-skid pavement and colored stone permeable pavement.

After curing, it has high strength, high toughness and strong adhesion.

It can be directly bonded on the surface of asphalt, concrete, iron plate, wood board and other materials with high extensibility, good flame retardancy, strong corrosion resistance, oil stain resistance.

Key Features

1. Good anti-skid performance

It can significantly increase the dry and anti-sliding performance of the road surface in rainy days, and shorten the braking distance by more than 40%

2. Various colors are available, bright and lasting

The non-slip aggregate is made of many kinds of color and never-fading colored ceramic particles, which can ensure bright color and durable.

3. Thickness 2-5mm

The thickness is thin and the weight is light, which will not increase the bearing burden of bridges and pavement foundations.

4. Good waterproof performance

The material makes the pavement surface closed and has good waterproof performance.

5. Reduce vehicle noise

Absorb sound waves, reduce noise by 6-7 decibels, and reduce noise by about 30%

6. Good weather resistance

Low temperature brittleness is low, which is beneficial to use in severe cold areas. Excellent thermal aging performance and high temperature stability.Wide bonding range, suitable for a variety of materials

7. Effectively extend the service life of roads

Strong rutting resistance, reducing or preventing road surface cracking, and improving service life

Typical Applications

Road intersections, ramps, bends, mountain roads, narrow roads, deceleration areas, greenways, sidewalks, bicycle lanes, bus lanes, parks, squares, scenic spots, etc.
