Ti-intro CME™ cationic molecular emulsion penetrant is a titanium dioxide (TiO₂) penetrant in a carrier liquid that penetrates asphalt and concrete pavement, delivering TiO₂ to the surface and upper matrix of the structure. Ti-intro CME pollution-reducing penetrant uniformly distributes TiO₂ throughout the pavement’s upper matrix area in a process known as distributive embedding. Once delivered by the selective penetrant, the TiO₂ catalytic material creates an electrochemical reaction that reduces atmospheric vehicle exhaust gas by removing nitrogen oxides (NOx), volatile organic compounds (VOCs), and other pollutants generated by automotive, bus and truck traffic.

Ti-intro CME penetrant is the ideal solution for DOTs, municipalities, or counties, gated communities or parking lots, and airports or bridges where the government or private agency managing them is interested in removing NOx, VOCs and other pollutants from the surrounding atmosphere.

The “Laboratory Investigation of the Effect of TiO2 Topical Treatments on Concrete and Asphalt Samples,” conducted by Texas A&M Transportation Institute, examines the effectiveness of PTI’s titanium-oxide-enhanced chemistries and is now complete. This study offers a general overview of the application of titanium dioxide (TiO2) to concrete and asphalt surfaces to impart air pollution remediation properties. It is available upon request.
