"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.

"High-Brown SA" is a heat-welded modified asphalt emulsion for waterproofing construction, made from highly rigid modified asphalt. By applying it in large quantities (over 0.8 liters/m²) using a dedicated distributor on the base layer, a thick tack coat film is formed. When a porous mixture is laid on the surface, the asphalt film fills the voids beneath the porous mixture through heat welding, creating a waterproof layer that protects the base layer. After decomposition, it adheres poorly to tires, making it less likely for the tack coat to be disturbed even if construction vehicles enter, ensuring waterproofing while promoting the integration of the layered structure and preventing dirt on surrounding roads. 【Features】 ○ NETIS registration number: SK-140004-VE ○ By applying over 0.8 liters/m², it can achieve high waterproofing functionality → The permeability coefficient becomes 10⁻¹ to 10⁻² cm/s smaller compared to when not applied ○ By laying a heated mixture on the surface, it exhibits strong adhesion due to heat welding → It suppresses slipping between materials and inhibits aggregate dispersion ○ It fills cracks in existing pavement surfaces and suppresses reflection cracks For more details, please contact us or download the catalog.
