Hyperdesmo PB 2

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.
Hyperdesmo PB 2K provides root-resistant protection

Waterproofing and protection:

On asbestos-cement sheets and metal sheets.
On gypsum boards and cement boards.
On bituminous membranes (also for repairs).
In bathrooms, verandas, and balconies (under tiles).
In planters/flower beds – green roofs and terraces (protected).
In non-potable water tanks.
In basements and foundations.

It polymerizes (dries) quickly.
Suitable also for high-thickness membranes; no bubbles are formed.
Due to its low modulus of elasticity, it bridges substrate micro-cracks very effectively.
Excellent adhesion to various types of surfaces, with or without the use of a primer.
Resistant to high temperatures without the membrane softening.
Maximum operating temperature: 80°C.
High resistance to cold: the membrane remains elastic down to –40°C.
Excellent mechanical properties, high tensile strength and elasticity.
Excellent chemical resistance.
Vapor barrier.
Can also be used as a joint sealant.
