What is PMMA technology and why is it changing standards in road construction?
Material: PMMA (polymethyl methacrylate) is a two-component cold plastic resin that forms an extremely strong bond with the substrate after a chemical reaction.
Binding: Unlike conventional paints, which only form a surface film, the WeTraffic system becomes an integral part of the roadway.
Result: This technology is changing standards due to its extreme mechanical resistance, cure rate, and ability to retain both color and roughness for many years.
What is the main difference between a WeTraffic safety surface and a conventional horizontal marking with plastic or paint?
Durability and flexibility: While regular paint wears off quickly and standard thermoplastics can crack in frosts, WeTraffic's PMMA trowel remains flexible and highly resistant to temperature fluctuations. It is this [internal elasticity and specific formula] (Link to: How PMMA chemical bonding takes place...) that is essential for a long life without defects.
Surface Functionality: WeTraffic is not just a “tagging”, but a full-surface functional surface that actively protects the underlying communications.
Technical options: The system allows variable adjustment of roughness (roughness) using mineral fillers, which conventional paints or plastics cannot do to such an extent.
How does the chemical bond of PMMA with the substrate take place and why does the surface not crack due to it?
Cold polymerization: The uniqueness of PMMA lies in the process in which the material, after mixing with the catalyst, chemically “anchors” directly into the pores of asphalt or concrete.
Unitary unit: This bond is so strong that the surface does not form a separate fragile layer, but flexibly works together with the substrate. This is fundamentally different from [traditional plastic coatings that are too stiff] (Link to: Article No. 1 on cracking).
Elimination of cracking: Thanks to this internal elasticity, the WeTraffic system excellently resists stress during temperature changes, eliminating the risk of cracking and flaking.
