Primer, also known as primer (primer), is used for pre-treatment of pavement before hot-melt marking. It is the binder between hot-melt marking and pavement. The organic solvent in the primer is easy to wet the road surface. While wetting the road surface, the resin in the primer covers the coated road surface and forms a film It is conducive to the combination of the coating and the formed film at high temperature. Enhance the adhesion between markings and pavement.

The standardized application of bottom oil can avoid the appearance of film peeling and film cracking in the construction of hot-melt marking.
