Paintable, rapid, high modulus polyurethane sealant
and adhesive
Mapeflex PU 45 FT hardens following its reaction with atmospheric humidity and its special characteristics offers a
guarantee of long service life. It may be used on both horizontal and vertical surfaces.
The product is ready to use and is available in both metal cartridges and soft cartridges equipped with a special extrusion
gun, which makes the product particularly easy to apply.
The consistency of the product is ideal for quick application and its rapid-hardening characteristics allows the surface to
be put into service quickly with resulting economic advantages.
Before painting over Mapeflex PU 45 FT make sure it is completely polymerised.
We recommend using elastomeric paint such as Elastocolor Paint after treating the surface of the sealant with Colorite
Performance. Always carry out preliminary tests to make sure the sealant and paint are compatible.
