Mapeflex PU65


A two component polyurethane elastomeric sealant specifically developed for highway construction joints and for filling/ sealing anchoring heads made from pre-formed rubber, reinforced rubber and steel road joints carried between adjacent decks and between decks and abutments of road substructures, such as roads, railways and airports.

Can be used as a connection sealant between prefabricated road joints and the adjacent bituminous conglomerate, creating a seal between the two elements while guaranteeing considerable surface hardness and mechanical resistance to rolling and sliding friction.

Mapeflex PU65 is resistant to bad weather and deformability due to compression, with good tensile and shear strength. It can be used for surface sealing of the anchoring heads of the pre-formed rubber slabs.
