PU Resin - 2-component Polyurethane Resin

PU resin 2-component polyurethane resin

Elastic injection resin and coating resin - solvent-free

Product description:
MAFA PU resin is a solvent-free, unfilled and transparent, 2-component polyurethane resin. In the mixture, it is a milky cloudy liquid with relatively low viscosity.

Application areas:

• Used for elastic sealing of cracks, imperfections, voids, expansion joints and working joints in civil engineering.
• It is used in all types of structures and building structures.
• Suitable for filling in the casting or low pressure process as well as for crack injection in the medium to high pressure process.
• Seals properly against pressurized water.
• Is also used as an elastic, wear-resistant coating material.

Mode of action / properties:

• Hardens after processing to a shrink-free, permanently elastic polymer.
• Maintains its elasticity even at minus degrees.
• All polyurethanes have a fantastic flank adhesion and can be applied to dry, damp or wet flanks.
• Is absolutely weather-resistant and offers excellent resistance to chemicals.
• Tilts like all PU materials to yellowing and is not UV stable.
• Is physiologically and ecologically harmless when cured.
