Alchimica HYPERDESMO - 300

HYPERDESMO®-300 is a single-component, highly chemical-resistant polyurethane/polyurea liquid membrane designed for demanding waterproofing applications. This product boasts excellent chemical and mechanical properties, as well as very high abrasion resistance, making it ideal for tough and demanding waterproofing tasks. HYPERDESMO®-300 displays crack-bridging properties over a wide range of extremely high or low temperatures. The product's thixotropic rheology allows for easy application on sloped and vertical substrates without sagging. It contains a very low amount of solvent, is non-flammable, and is classified as “non-IMO” or ADR during transportation.

Key Features

• Excellent crack-bridging properties.
• Low solvent content, non-flammable.
• Superior chemical resistance. Can withstand petrochemicals, salts, and chlorine that commonly attack bridge decks or might be present in swimming pools and water tanks.
• Thixotropic, can be applied on any complex structure, ensuring complete seamless and homogeneous coverage of uneven concrete surfaces usually encountered on bridge decks or vertical surfaces found in swimming pools and tanks.
• Excellent mechanical properties, high elasticity, tensile, and tear strength. Can withstand stresses from heavy asphalt application machinery.
• Exceptional compatibility with asphalt overlays without needing an adhesion layer.
• Highly hydrophobic.
• Compatible with ALCHIMICA’s standard primers and topcoats.

Typical Usage

• Waterproofing of swimming pools (under tiles)
• Waterproofing of chemically treated tanks
• Waterproofing of high-traffic roofs
• Waterproofing of bridge decks
