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.
• Fast curing.
• 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.
