AplicaPROOF PUA P EXP
Expandable, pure polyurea membrane with thermal insulation capabilities
• Pure polyurea that expands 5 to 7 times its initial thickness
• Ideal for metal and fibre cement substrates
• Thermal insulatio
AplicaPROOF PUA P EXP is a dual-component sprayable aromatic coating, suitable for waterproofing, thermal insulation, protection and sealing. It is composed of two highly reactive liquid components, isocyanates and amines, which are mixed using our specific spraying equipment) or similar, to form a solid, continuous, seamless, watertight and waterproof pure polyurea membrane, specially designed for application on elements with structural movements. This polyurea is capable of final expansion of 5 to 7 times its initial thickness.
AplicaPROOF PUA P EXP
For the waterproofing and protection of concrete and roofs on metal substrates:
• Fibre cement and metal roofs.
• Pitched roofs, terraces, balconies and roofs.
• Concrete slabs, retaining walls and foundations.
Metal drums of 225 kg each (Component A: isocyanates and Component B: amines).
These safety recommendations during handling are necessary during the execution process, as well as in the processes before and after the execution in situations of exposure to machinery under load.
• Respiratory protection: When handling in aerosol form, an approved air-purifying respirator must be worn.
• Skin Protection: Wear rubber gloves. Remove immediately after contamination. Wear clean clothes that cover the whole body. Wash thoroughly with soap and water after work and before eating, drinking or smoking. Contaminated clothing should be washed and/or dry cleaned.
• Eye/face protection: Wear safety goggles to avoid splashing and exposure to spray mist.
• Waste: Waste generation shall be avoided or minimised. Incinerate under controlled conditions in accordance with local and national laws and regulations.
• In any case, please refer to the existing product safety data sheets, which are publicly available.
For formation, it is necessary to mix the two initial liquid components, isocyanates and amines/polyols, by means of the dosing equipment.
The most general parameters of this equipment shall be the following:
• Isocyanate heater temperature: 78-80ºC
• Amine heater temperature: 65-70ºC
• Hose temperature: ±70ºC
• Operating pressure: 2,500-3,000 psi
• Recommended mixing chamber: use mechanical purge chamber.
These temperature and pressure parameters must be assessed, ratified or slightly varied by the application agent, depending on the conditions of each climatic zone, climatic situation or according to the specifications of the spraying equipment.
The recommendations for use are based on our knowledge and experience. The technical data have been obtained under normal laboratory conditions and may vary depending on the conditions of installation. As the conditions of application are beyond our control, the information in this sheet does not imply any liability on the part of the company.
