Technical Information

Mapeflex PB25 is a two-component thixotropic sealant composed of a polyurethane polymer devoid of free isocyanates and a special hardener which contains tar of petroliferous origin, according to a formula developed in the Mapei research laboratories. Mixing Part A with Part B, Mapeflex PB25 becomes a black thixotropic paste, easy to apply even on vertical surfaces with a flat trowel.

Once hardened, which occurs after 24-36 hours by chemical reaction alone and without shrinkage, Mapeflex PB25 becomes flexible, resistant to hydrocarbons and water.

Where To Use:

• Sealing of joints in concrete vertical elements subject to weak chemical attacks.

• Sealing of joints in concrete flooring subject for accidental reasons to contact with hydrocarbons.
