DEMCO POLYUREA /HB

Description

DEMCO POLYUREA / HB is a fast curing, 100% solid (solvent-free), aromatic, flexible, pure polyurea hybrid system that can be applied as a two-component spray on metal, concrete, wood and other recommended surfaces. It can be applied up to -30 ° C ambient temperature thanks to its gel speed. Care should be taken that the applied surface is moisture free (max. 4%). For a healthy application, it is recommended that the applied surface moisture ratio be below 5%. DEMCO POLYUREA / HB is fast curing and touch drying time is less than 30 seconds, elongation is 435% and has a flexible structure, Shore 45 – 50 D hardness. With these features, it adheres firmly to the surface, prevents its contact with the external environment, prevents water and air permeability, and is resistant to abrasion, shaking and impacts
