It has interlayer adhesion of composite materials, reducing asphalt adhesion to tires!
"High Tack AS" is an emulsion developed for tack coats with the aim of significantly reducing adhesion to tires. Compared to conventional PK-4 and PKR-T, it reduces asphalt adhesion to tires. It is less likely to adhere to tires and does not dirty the surrounding pavement. Additionally, it has superior interlayer adhesion compared to PKR-T. 【Features】 ■ Compatible with PKM-T ■ Significantly reduces adhesion to tires ■ Has excellent interlayer adhesion *For more details, please refer to the PDF document or feel free to contact us.

Company information
Showa Asphalt Industry Co., Ltd. is a company engaged in various asphalt-related businesses, including asphalt emulsions, modified asphalt, asphalt mixtures, and straight asphalt. Showa Asphalt Industry takes the concerns of our customers, the local community, and our employees seriously, striving to become a unique company that brings joy to our customers by utilizing our unique technological capabilities to propose and improve solutions. We aim for business development and social contribution. For example, after opening our Okinawa branch in 1972, we found that customers in the Sakishima Islands were performing a very dangerous task of opening the top of each drum of asphalt to dissolve the asphalt liquid for use. In response to customer requests for improvement, we developed the 10-ton container asphalt distribution system. This system significantly contributed to safety and improved work efficiency by eliminating direct contact between workers and high-temperature asphalt. Showa Asphalt Industry Co., Ltd. values the voices of our customers and will actively challenge ourselves to do what only SHOREKI can do.
