Sanwin SC401T Transparent Topcoat is a colorless and transparent acrylic pavement paint. It is commonly used as the surface layer of colored anti-slip pavements and is usually applied as the final step in construction.
Once cured, the film formed by the transparent topcoat is firm and dense. It not only plays a role in stabilizing aggregates, but also keeps the surface of colored anti-slip pavements clean. Properly applied transparent topcoat can extend the service life of colored pavements to more than 3 years and is easy to clean.
Sanying SC401T Transparent Topcoat is an ideal choice for three-layer colored anti-slip pavement construction and is widely used in both expressways and urban roads.

Construction Recommendations
Surface Preparation
The primer is completely cured, aggregates are firmly bonded, and excess aggregates have been removed. The surface to be coated is dry and flat.
Environment
The acceptable operating temperature is 5-45℃, and the ground humidity should not exceed 70% RH.
Premixing
Add the curing agent to the coating in the specified ratio and stir evenly at low speed with an electric mixer.
Application
Evenly apply the coating to the surface of anti-slip aggregates using a roller brush or special-purpose tools.
Aggregate
Recommended aggregate particle size is 1-5mm
Cleaning
A sufficient amount of cleaning agent should be provided at the construction site. Tools must be cleaned immediately after construction; otherwise, it will be extremely difficult to clean once the coating is fully cured.
