Hyperdesmo-PB-2K is a fast-curing, two-component, bitumen-extended polyurethane fluid. It produces a highly elastic membrane with strong adhesion to many types of surfaces and excellent mechanical and chemical resistance properties.
It is based on a pure elastomeric hydrophobic polyurethane resin extended with chemicals polymerized virgin bitumen. Apply with brush, roller, spatula or airless spraying. Minimum consumption: 1.0-1.5 lt/m².
Features and Benefits
Components easily mixed, 1:1 by volume.
Thick, bubble free, membrane possible.
Being a two component product means that the quantities not mixed can be stored for later use.
Its low modulus gives it excellent substrate crack-bridging properties.
Excellent adhesion on almost any surface, with or without the use of special primers.
No thinning is required but SOLVENT-01 may be used.
Excellent thermal resistance, the product never turns soft. Max temperature 80ᴼc, max shock temperature 200ᴼc.
Resistance in the cold: The film remains elastic even down to -40ᴼc.
Excellent mechanical properties, high elongation, tensile and tear strength, high abrasion resistance.
Good water vapor barrier properties.
Can also be used as a joint sealant.
