DESCRIPTION

Technical Information:

Mapeflex PU 65 is an elastomeric polyurethane based sealant. It is composed of two pre-dosed components: part A is a resin, part B is a hardener. After mixing the two components, the product becomes a cohesive pourable mixture. When large voids have to be filled, Mapeflex PU 65 can be mixed with Quartz 0.5, a mixture with controlled granulometry of alluvium spherical quartz of light grey colour with maximum aggregate size of 0.5 mm, up to a maximum ratio of 1:1 by weight. The addition of an aggregate enhances the mechanical characteristics of friction resistance and the thixotropy of the product, but the sealant deformability is decreased. Mapeflex PU 65 is solvent free and the slight smell, that can be noticed, is only due to the resin. Mapeflex PU 65 cross-links because of the reaction between resin and hardener. The substrate temperature and the environment can influence anyway the cross-linking time of the sealant: high temperatures reduce the workability time of the mixture and accelerate the setting time. Low temperatures make the reaction time longer. The curing time of the sealant may be reduced if required by adding the specific accelerator Mapeflex PU 65 Catalyst. After crosslinking, Mapeflex PU 65 becomes an elastomeric substance characterized by a high surface hardness which can deform under compressive, tensile and shear loads. Mapeflex PU 65 is suitable to support vehicular traffic, on roads, freeways and highways. Mapeflex PU 65 is the ideal product to carry out sealing substrates subject to limited movements and heavy loads.

Where To Use:

Mapeflex PU 65 is 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 between adjacent decks and between deck and abutments of road substructures, such as roads, railways, airports. Due to its physical and mechanical properties, Mapeflex PU 65 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 friction. Mapeflex PU 65 is resistant to bad weather conditions and deformability due to compression, with good tensile and shear strength. Mapeflex PU 65 can be used for surface sealing of the anchoring bolts in pre-formed rubber sections. Mapeflex PU 65, after mixing the two components A+B, can be added to specific mineral fillers which allow it to obtain different mechanical and deformation properties depending on the different foreseen stresses.
