ABSTRACT:
The polyurethane-resin layer and adhesive layer marking strip composition is conformant to the roadway without tearing, has a high elongation, a high permanent deformation, and a low elastic return due to high molecular weight and high sterical impediment.
One example of a high molecular weight and high sterical impediment is a sterically-impeded high-volume aromatic ring which reduces crystallization.
