NanoTac

NanoTac is a high-performance tack coat additive that improves bond strength between asphalt layers, enhances emulsion performance, and reduces tracking. NanoTac-enhanced emulsions form a durable chemical bond between the bitumen and the underlying surface. The permanent anchoring of the bitumen ensures complete and homogeneous load transfer between the various layers of the pavement, while significantly reducing the potential for the bitumen to track and be prone to moisture damage. Due to the permanent chemical bond formed between the bitumen and underlying surface, emulsions that contain NanoTac achieve very high bond strengths, even at lower residual bitumen contents. This enables a significant cost saving on both milled and unmilled surfaces. NanoTac-containing emulsions can be diluted to the extent of 20% residual bitumen content, while still maintaining very high bond strengths.
