Asphalt sealer formulators face many challenges, from finding cost effective materials to achieving formulation cohesion. All at the prospect that they can deliver a product with the performance the consumers expect, at a price they can afford.

Omya application experts stand at the ready with Omyaroad to assist you with all your formulation prospecting whether it be on or off the road.

Benefits of Omyaroad

  • Reduced asphalt emulsion demand
  • Improved durability
  • Enhanced color

Reduced asphalt emulsion demand

Asphalt sealers filled with Omyaroad products decrease interfacial surface area, thereby, reducing the demand for asphalt emulsion in the formulation.

 

Omyaroad and Omyaroad F have a morphology that delivers the lowest interfacial surface area at all size classifications when compared to the comparable alternatives for asphalt sealers.

Improved durability

According to ISSA (#100) and ASTM (D3910-15) testing, asphalt sealers, containing Omyaroad show improved wet track abrasion results.

 

When you take a bi-modal approach utilizing both Omyaroad and Omyaroad F, invoking particle packing theory, this allows the formulator to take advantage of several additional cost cutting and performance enhancements.

Enhanced color

Omyaroad accentuates the properties of black pigments promoting a darker, richer, black color and enhances color development as asphalt sealers age.
